Secondary research is the analysis, summary or synthesis of already existing published research. Instead of collecting original data, as in primary research , secondary research involves data or the results of data analyses already collected.

It is generally published in books, handbooks, textbooks, articles, encyclopedias, websites, magazines, literature reviews and meta-analyses. These are usually referred to as secondary sources .

Secondary research is a good place to start when wanting to acquire a broad view of a research area. It is usually easier to understand and may not require advanced training in research design and statistics.

Secondary Research Examples

1. literature review.

A literature review summarizes, reviews, and critiques the existing published literature on a topic.

Literature reviews are considered secondary research because it is a collection and analysis of the existing literature rather than generating new data for the study.

They hold value for academic studies because they enable us to take stock of the existing knowledge in a field, evaluate it, and identify flaws or gaps in the existing literature. As a result, they’re almost universally used by academics prior to conducting primary research.

Example 1: Workplace stress in nursing: a literature review

Citation: McVicar, A. (2003). Workplace stress in nursing: a literature review.  Journal of advanced nursing ,  44 (6), 633-642. Source: https://doi.org/10.1046/j.0309-2402.2003.02853.x

Summary: This study conducted a systematic analysis of literature on the causes of stress for nurses in the workplace. The study explored the literature published between 2000 and 2014. The authors found that the literature identifies several main causes of stress for nurses: professional relationships with doctors and staff, communication difficulties with patients and their families, the stress of emergency cases, overwork, lack of staff, and lack of support from the institutions. They conclude that understanding these stress factors can help improve the healthcare system and make it better for both nurses and patients.

Example 2: The impact of shiftwork on health: a literature review

Citation: Matheson, A., O’Brien, L., & Reid, J. A. (2014). The impact of shiftwork on health: a literature review.  Journal of Clinical Nursing ,  23 (23-24), 3309-3320. Source: https://doi.org/10.1111/jocn.12524

In this literature review, 118 studies were analyzed to examine the impact of shift work on nurses’ health. The findings were organized into three main themes: physical health, psychosocial health, and sleep. The majority of shift work research has primarily focused on these themes, but there is a lack of studies that explore the personal experiences of shift workers and how they navigate the effects of shift work on their daily lives. Consequently, it remains challenging to determine how individuals manage their shift work schedules. They found that, while shift work is an inevitable aspect of the nursing profession, there is limited research specifically targeting nurses and the implications for their self-care.

Example 3: Social media and entrepreneurship research: A literature review

Citation: Olanrewaju, A. S. T., Hossain, M. A., Whiteside, N., & Mercieca, P. (2020). Social media and entrepreneurship research: A literature review.  International Journal of Information Management ,  50 , 90-110. Source: https://doi.org/10.1016/j.ijinfomgt.2019.05.011

In this literature review, 118 studies were analyzed to examine the impact of shift work on nurses’ health. The findings were organized into three main themes: physical health, social health , and sleep. The majority of shift work research has primarily focused on these themes, but there is a lack of studies that explore the personal experiences of shift workers and how they navigate the effects of shift work on their daily lives. Consequently, it remains challenging to determine how individuals manage their shift work schedules. They found that, while shift work is an inevitable aspect of the nursing profession, there is limited research specifically targeting nurses and the implications for their self-care.

Example 4: Adoption of electric vehicle: A literature review and prospects for sustainability

Citation: Kumar, R. R., & Alok, K. (2020). Adoption of electric vehicle: A literature review and prospects for sustainability.  Journal of Cleaner Production ,  253 , 119911. Source: https://doi.org/10.1016/j.jclepro.2019.119911

This study is a literature review that aims to synthesize and integrate findings from existing research on electric vehicles. By reviewing 239 articles from top journals, the study identifies key factors that influence electric vehicle adoption. Themes identified included: availability of charging infrastructure and total cost of ownership. The authors propose that this analysis can provide valuable insights for future improvements in electric mobility.

Example 5: Towards an understanding of social media use in the classroom: a literature review

Citation: Van Den Beemt, A., Thurlings, M., & Willems, M. (2020). Towards an understanding of social media use in the classroom: a literature review.  Technology, Pedagogy and Education ,  29 (1), 35-55. Source: https://doi.org/10.1080/1475939X.2019.1695657

This study examines how social media can be used in education and the challenges teachers face in balancing its potential benefits with potential distractions. The review analyzes 271 research papers. They find that ambiguous results and poor study quality plague the literature. However, they identify several factors affecting the success of social media in the classroom, including: school culture, attitudes towards social media, and learning goals. The study’s value is that it organizes findings from a large corpus of existing research to help understand the topic more comprehensively.

2. Meta-Analyses

Meta-analyses are similar to literature reviews, but are at a larger scale and tend to involve the quantitative synthesis of data from multiple studies to identify trends and derive estimates of overall effect sizes.

For example, while a literature review might be a qualitative assessment of trends in the literature, a meta analysis would be a quantitative assessment, using statistical methods, of studies that meet specific inclusion criteria that can be directly compared and contrasted.

Often, meta-analysis aim to identify whether the existing data can provide an authoritative account for a hypothesis and whether it’s confirmed across the body of literature.

Example 6: Cholesterol and Alzheimer’s Disease Risk: A Meta-Meta-Analysis

Citation: Sáiz-Vazquez, O., Puente-Martínez, A., Ubillos-Landa, S., Pacheco-Bonrostro, J., & Santabárbara, J. (2020). Cholesterol and Alzheimer’s disease risk: a meta-meta-analysis.  Brain sciences ,  10 (6), 386. Source: https://doi.org/10.3390/brainsci10060386

This study examines the relationship between cholesterol and Alzheimer’s disease (AD). Researchers conducted a systematic search of meta-analyses and reviewed several databases, collecting 100 primary studies and five meta-analyses to analyze the connection between cholesterol and Alzheimer’s disease. They find that the literature compellingly demonstrates that low-density lipoprotein cholesterol (LDL-C) levels significantly influence the development of Alzheimer’s disease, but high-density lipoprotein cholesterol (HDL-C), total cholesterol (TC), and triglycerides (TG) levels do not show significant effects. This is an example of secondary research because it compiles and analyzes data from multiple existing studies and meta-analyses rather than collecting new, original data.

Example 7: The power of feedback revisited: A meta-analysis of educational feedback research

Citation: Wisniewski, B., Zierer, K., & Hattie, J. (2020). The power of feedback revisited: A meta-analysis of educational feedback research.  Frontiers in Psychology ,  10 , 3087. Source: https://doi.org/10.3389/fpsyg.2019.03087

This meta-analysis examines 435 empirical studies research on the effects of feedback on student learning. They use a random-effects model to ascertain whether there is a clear effect size across the literature. The authors find that feedback tends to impact cognitive and motor skill outcomes but has less of an effect on motivational and behavioral outcomes. A key (albeit somewhat obvious) finding was that the manner in which the feedback is provided is a key factor in whether the feedback is effective.

Example 8: How Much Does Education Improve Intelligence? A Meta-Analysis

Citation: Ritchie, S. J., & Tucker-Drob, E. M. (2018). How much does education improve intelligence? A meta-analysis.  Psychological science ,  29 (8), 1358-1369. Source: https://doi.org/10.1177/0956797618774253

This study investigates the relationship between years of education and intelligence test scores. The researchers analyzed three types of quasiexperimental studies involving over 600,000 participants to understand if longer education increases intelligence or if more intelligent students simply complete more education. They found that an additional year of education consistently increased cognitive abilities by 1 to 5 IQ points across all broad categories of cognitive ability. The effects persisted throughout the participants’ lives, suggesting that education is an effective way to raise intelligence. This study is an example of secondary research because it compiles and analyzes data from multiple existing studies rather than gathering new, original data.

Example 9: A meta-analysis of factors related to recycling

Citation: Geiger, J. L., Steg, L., Van Der Werff, E., & Ünal, A. B. (2019). A meta-analysis of factors related to recycling.  Journal of environmental psychology ,  64 , 78-97. Source: https://doi.org/10.1016/j.jenvp.2019.05.004

This study aims to identify key factors influencing recycling behavior across different studies. The researchers conducted a random-effects meta-analysis on 91 studies focusing on individual and household recycling. They found that both individual factors (such as recycling self-identity and personal norms) and contextual factors (like having a bin at home and owning a house) impacted recycling behavior. The analysis also revealed that individual and contextual factors better predicted the intention to recycle rather than the actual recycling behavior. The study offers theoretical and practical implications and suggests that future research should examine the effects of contextual factors and the interplay between individual and contextual factors.

Example 10: Stress management interventions for police officers and recruits

Citation: Patterson, G. T., Chung, I. W., & Swan, P. W. (2014). Stress management interventions for police officers and recruits: A meta-analysis.  Journal of experimental criminology ,  10 , 487-513. Source: https://doi.org/10.1007/s11292-014-9214-7

The meta-analysis systematically reviews randomized controlled trials and quasi-experimental studies that explore the effects of stress management interventions on outcomes among police officers. It looked at 12 primary studies published between 1984 and 2008. Across the studies, there were a total of 906 participants. Interestingly, it found that the interventions were not effective. Here, we can see how secondary research is valuable sometimes for showing there is no clear trend or consensus in existing literature. The conclusions suggest a need for further research to develop and implement more effective interventions addressing specific stressors and using randomized controlled trials.

3. Textbooks

Academic textbooks tend not to present new research. Rather, they present key academic information in ways that are accessible to university students and academics.

As a result, we can consider textbooks to be secondary rather than primary research. They’re collections of information and research produced by other people, then re-packaged for a specific audience.

Textbooks tend to be written by experts in a topic. However, unlike literature reviews and meta-analyses, they are not necessarily systematic in nature and are not designed to progress current knowledge through identifying gaps, weaknesses, and strengths in the existing literature.

Example 11: Psychology for the Third Millennium: Integrating Cultural and Neuroscience Perspectives

This textbook aims to bridge the gap between two distinct domains in psychology: Qualitative and Cultural Psychology , which focuses on managing meaning and norms, and Neuropsychology and Neuroscience, which studies brain processes. The authors believe that by combining these areas, a more comprehensive general psychology can be achieved, which unites the biological and cultural aspects of human life. This textbook is considered a secondary source because it synthesizes and integrates information from various primary research studies, theories, and perspectives in the field of psychology.

Example 12: Cultural Sociology: An Introduction

Citation: Bennett, A., Back, L., Edles, L. D., Gibson, M., Inglis, D., Jacobs, R., & Woodward, I. (2012).  Cultural sociology: an introduction . New York: John Wiley & Sons.

This student textbook introduces cultural sociology and proposes that it is a valid model for sociological thinking and research. It gathers together existing knowledge within the field to prevent an overview of major sociological themes and empirical approaches utilized within cultural sociological research. It does not present new research, but rather packages existing knowledge in sociology and makes it understandable for undergraduate students.

Example 13: A Textbook of Community Nursing

Citation: Chilton, S., & Bain, H. (Eds.). (2017).  A textbook of community nursing . New York: Routledge.

This textbook presents an evidence-based introduction to professional topics in nursing. In other words, it gathers evidence from other research and presents it to students. It covers areas such as care approaches, public health, eHealth, therapeutic relationships, and mental health. Like many textbooks, it brings together its own secondary research with user-friendly elements like exercises, activities, and hypothetical case studies in each chapter.

4. White Papers

White papers are typically produced within businesses and government departments rather than academic research environments.

Generally, a white paper will focus on a specific topic of concern to the institution in order to present a state of the current situation as well as opportunities that could be pursued for change, improvement, or profit generation in the future.

Unlike a literature review, a white paper generally doesn’t follow standards of academic rigor and may be presented with a bias toward, or focus on, a company or institution’s mission and values.

Example 14: Future of Mobility White Paper

Citation: Shaheen, S., Totte, H., & Stocker, A. (2018). Future of Mobility White Paper.  UC Berkeley: Institute of Transportation Studies at UC Berkeley Source: https://doi.org/10.7922/G2WH2N5D

This white paper explores the how transportation is changing due to concerns over climate change, equity of access to transit, and rapid technological advances (such as shared mobility and automation). The authors aggregate current information and research on key trends, emerging technologies/services, impacts on California’s transportation ecosystem, and future growth projections by reviewing state agency publications, peer-reviewed articles, and forecast reports from various sources. This white paper is an example of secondary research because it synthesizes and integrates information from multiple primary research sources, expert interviews, and input from an advisory committee of local and state transportation agencies.

Example 15: White Paper Concerning Philosophy of Education and Environment

Citation: Humphreys, C., Blenkinsop, S. White Paper Concerning Philosophy of Education and Environment.  Stud Philos Educ   36 (1): 243–264. Source: https://doi.org/10.1007/s11217-017-9567-2

This white paper acknowledges the increasing significance of climate change, environmental degradation, and our relationship with nature, and the need for philosophers of education and global citizens to respond. The paper examines five key journals in the philosophy of education to identify the scope and content of current environmental discussions. By organizing and summarizing the located articles, it assesses the possibilities and limitations of these discussions within the philosophy of education community. This white paper is an example of secondary research because it synthesizes and integrates information from multiple primary research sources, specifically articles from the key journals in the field, to analyze the current state of environmental discussions.

5. Academic Essays

Students’ academic essays tend to present secondary rather than primary research. The student is expected to study current literature on a topic and use it to present a thesis statement.

Academic essays tend to require rigorous standards of analysis, critique, and evaluation, but do not require systematic investigation of a topic like you would expect in a literature review.

In an essay, a student may identify the most relevant or important data from a field of research in order to demonstrate their knowledge of a field of study. They may also, after demonstrating sufficient knowledge and understanding, present a thesis statement about the issue.

Secondary research involves data that has already been collected. The published research might be reviewed, included in a meta-analysis, or subjected to a re-analysis.

These findings might be published in a peer-reviewed journal or handbook, become the foundation of a book for public consumption, or presented in a more narrative form for a popular website or magazine.

Sources for secondary research can range from scientific journals to government databases and archived data accumulated by research institutes.

University students might engage in secondary research to become familiar with an area of research. That might help spark an intriguing hypothesis for a research project of master’s thesis.

Secondary research can yield new insights into human behavior , or confirm existing conceptualizations of psychological constructs.

In the social sciences, a secondary source is usually a scholar book, journal article, or digital or print document that was created by someone who did not directly experience or participate in the events or conditions under investigation. Secondary sources are not evidence per se, but rather, provide an interpretation, analysis, or commentary derived from the content of primary source materials and/or other secondary sources.

Value of Secondary Sources

To do research, you must cite research. Primary sources do not represent research per se, but only the artifacts from which most research is derived. Therefore, the majority of sources in a literature review are secondary sources that present research findings, analysis, and the evaluation of other researcher's works.

Reviewing secondary source material can be of valu e in improving your overall research paper because secondary sources facilitate the communication of what is known about a topic. This literature also helps you understand the level of uncertainty about what is currently known and what additional information is needed from further research. It is important to note, however, that secondary sources are not the subject of your analysis. Instead, they represent various opinions, interpretations, and arguments about the research problem you are investigating--opinions, interpretations, and arguments with which you may either agree or disagree with as part of your own analysis of the literature.

Examples of secondary sources you could review as part of your overall study include:     * Bibliographies [also considered tertiary]     * Biographical works     * Books, other than fiction and autobiography     * Commentaries, criticisms     * Dictionaries, Encyclopedias [also considered tertiary]     * Histories     * Journal articles [depending on the discipline, they can be primary]     * Magazine and newspaper articles [this distinction varies by discipline]     * Textbooks [also considered tertiary]     * Web site [also considered primary]

Types of Secondary Research Methods with Examples

Secondary research methods offer a range of approaches for leveraging existing data, each providing value in extracting insights relevant to various business and academic needs. Understanding the unique advantages of each method can guide researchers in choosing the most appropriate approach for their specific objectives.

Literature Reviews

Literature reviews synthesize existing research and publications to identify trends, gaps, and consensus within a field of study. This method provides a comprehensive overview of what is already known about a topic, saving time and resources by building on existing knowledge rather than starting from scratch.

Real-World Example : A marketing firm conducting a literature review on consumer behavior in the digital age might uncover a trend towards increased mobile shopping. This insight leads to a strategic recommendation for a retail client to prioritize mobile app development and optimize their online store for mobile users, directly impacting the client's digital marketing strategy.

Data Mining

Data mining involves analyzing large sets of data to discover patterns, correlations, or trends that are not immediately apparent. This method can uncover hidden insights from the data that businesses can use to inform decision-making, such as identifying new market opportunities or optimizing operational efficiencies.

Real-World Example : Through data mining of customer purchase histories and online behavior data, a retail company identifies a previously unnoticed correlation between the purchase of certain products and the time of year. Utilizing this insight, the company adjusts its inventory levels and marketing campaigns seasonally, significantly boosting sales and customer satisfaction.

Meta-Analysis

Meta-analysis aggregates and systematically analyzes results from multiple studies to draw general conclusions about a research question. This method provides a high level of evidence by combining findings, offering a powerful tool for making informed decisions based on a broader range of data than any single study could provide.

Real-World Example : A pharmaceutical company uses meta-analysis to combine findings from various clinical trials of a new drug. The meta-analysis reveals a statistically significant benefit of the drug that was not conclusive in individual studies. This insight supports the company's application for regulatory approval and guides the development of marketing strategies targeting specific patient demographics.

Data Analysis

Secondary data analysis applies statistical techniques to analyze existing datasets, offering a cost-effective way to gain insights without the need for new data collection. This method can identify trends, patterns, and relationships that inform strategic planning and decision-making.

Real-World Example : An investment firm analyzes historical economic data and stock market trends using secondary data analysis. They identify a recurring pattern preceding market downturns. By applying this insight to their investment strategy, the firm successfully mitigates risk and enhances portfolio performance for their clients.

Content Analysis

Content analysis systematically examines the content of communication mediums to understand messages, themes, or biases . This qualitative method can reveal insights into public opinion, media representation, and communication strategies, offering valuable information for marketing, public relations, and media strategies.

Real-World Example : A technology company employs content analysis to review online customer reviews and social media mentions of its products. The analysis uncovers a common concern among customers about the usability of a product feature. Responding to this insight, the company revises its product design and launches a targeted communication campaign to address the concerns, improving customer satisfaction and brand perception.

Historical Research

Historical research examines past records and documents to understand historical contexts and trends, offering insights that can inform future predictions, strategy development, and understanding of long-term changes. This method is particularly valuable for understanding the evolution of markets, industries, or consumer behaviors over time.

Real-World Example : A consultancy specializing in sustainable business practices conducts historical research into the adoption of green technologies in the automotive industry. The research identifies key drivers and barriers to adoption over the decades. Leveraging these insights, the consultancy advises new green tech startups on strategies to overcome market resistance and capitalize on drivers of adoption, significantly impacting their market entry strategy.

Each of these secondary research methods provides distinct advantages and can yield valuable insights for businesses and researchers. By carefully selecting and applying the most suitable method(s), organizations can enhance their understanding of complex issues, inform strategic decisions, and achieve competitive advantage.

Disadvantages of Secondary Research

• Relevance and Specificity : Existing data may not perfectly align with the current research objectives, leading to potential mismatches in relevance and specificity.
• Data Quality and Accuracy : The quality and accuracy of secondary data can vary, depending on the source. Researchers must critically assess the credibility of their sources to ensure the reliability of their findings.
• Timeliness : Data may be outdated, especially in fast-moving sectors where recent information is crucial for making informed decisions.
• Limited Control Over Data : Researchers have no control over how data was collected and processed, which may affect its suitability for their specific research needs.

Secondary research, when approached with an understanding of its strengths and weaknesses, has the potential be a powerful tool. By effectively navigating its advantages and limitations, businesses can lay a solid foundation for informed decision-making and strategic planning.

Primary vs. Secondary Research: A Comparative Analysis

When undertaking a research project, understanding the distinction between primary and secondary research is pivotal. Both forms of research serve their own purposes and can complement each other in providing a comprehensive overview of a given topic.

What is Primary Research?

Primary research involves the collection of original data directly from sources. This method is firsthand and is specific to the researcher's questions or hypotheses.

The main advantage of primary research is its specificity and relevancy to the particular issue or question at hand. It offers up-to-date and highly relevant data that is directly applicable to the research objectives.

Example : A company planning to launch a new beverage product conducts focus groups and survey research to understand consumer preferences. Through this process, they gather firsthand insights on flavors, packaging, and pricing preferences specific to their target market.

What is Secondary Research?

Secondary research involves the analysis of existing information compiled and collected by others. It includes studies, reports, and data from government agencies, trade associations, and other organizations.

Secondary research provides a broad understanding of the topic at hand, offering insights that can help frame primary research. It is cost-effective and time-saving, as it leverages already available data.

Example : The same company explores industry reports, academic research, and market analyses to understand broader market trends, competitor strategies, and consumer behavior within the beverage industry.

Comparative Analysis

Synergistic Use in Research

The most effective research strategies often involve a blend of both primary and secondary research. Secondary research can serve as a foundation, helping to inform the development of primary research by identifying gaps in existing knowledge and refining research questions.

Understanding the distinct roles and benefits of primary and secondary research is crucial for any successful research project. By effectively leveraging both types of research, researchers can gain a deeper, more nuanced understanding of their subject matter, leading to more informed decisions and strategies. Remember, the choice between primary and secondary research should be guided by your research objectives, resources, and the specificity of information required.

Secondary research: definition, methods, & examples.

19 min read This ultimate guide to secondary research helps you understand changes in market trends, customers buying patterns and your competition using existing data sources.

In situations where you’re not involved in the data gathering process ( primary research ), you have to rely on existing information and data to arrive at specific research conclusions or outcomes. This approach is known as secondary research.

In this article, we’re going to explain what secondary research is, how it works, and share some examples of it in practice.

Free eBook: The ultimate guide to conducting market research

What is secondary research?

Secondary research, also known as desk research, is a research method that involves compiling existing data sourced from a variety of channels . This includes internal sources (e.g.in-house research) or, more commonly, external sources (such as government statistics, organizational bodies, and the internet).

Secondary research comes in several formats, such as published datasets, reports, and survey responses , and can also be sourced from websites, libraries, and museums.

The information is usually free — or available at a limited access cost — and gathered using surveys , telephone interviews, observation, face-to-face interviews, and more.

When using secondary research, researchers collect, verify, analyze and incorporate it to help them confirm research goals for the research period.

As well as the above, it can be used to review previous research into an area of interest. Researchers can look for patterns across data spanning several years and identify trends — or use it to verify early hypothesis statements and establish whether it’s worth continuing research into a prospective area.

How to conduct secondary research

There are five key steps to conducting secondary research effectively and efficiently:

1.    Identify and define the research topic

First, understand what you will be researching and define the topic by thinking about the research questions you want to be answered.

Ask yourself: What is the point of conducting this research? Then, ask: What do we want to achieve?

This may indicate an exploratory reason (why something happened) or confirm a hypothesis. The answers may indicate ideas that need primary or secondary research (or a combination) to investigate them.

2.    Find research and existing data sources

If secondary research is needed, think about where you might find the information. This helps you narrow down your secondary sources to those that help you answer your questions. What keywords do you need to use?

Which organizations are closely working on this topic already? Are there any competitors that you need to be aware of?

Create a list of the data sources, information, and people that could help you with your work.

3.    Begin searching and collecting the existing data

Now that you have the list of data sources, start accessing the data and collect the information into an organized system. This may mean you start setting up research journal accounts or making telephone calls to book meetings with third-party research teams to verify the details around data results.

As you search and access information, remember to check the data’s date, the credibility of the source, the relevance of the material to your research topic, and the methodology used by the third-party researchers. Start small and as you gain results, investigate further in the areas that help your research’s aims.

4.    Combine the data and compare the results

When you have your data in one place, you need to understand, filter, order, and combine it intelligently. Data may come in different formats where some data could be unusable, while other information may need to be deleted.

After this, you can start to look at different data sets to see what they tell you. You may find that you need to compare the same datasets over different periods for changes over time or compare different datasets to notice overlaps or trends. Ask yourself: What does this data mean to my research? Does it help or hinder my research?

5.    Analyze your data and explore further

In this last stage of the process, look at the information you have and ask yourself if this answers your original questions for your research. Are there any gaps? Do you understand the information you’ve found? If you feel there is more to cover, repeat the steps and delve deeper into the topic so that you can get all the information you need.

If secondary research can’t provide these answers, consider supplementing your results with data gained from primary research. As you explore further, add to your knowledge and update your findings. This will help you present clear, credible information.

Primary vs secondary research

Unlike secondary research, primary research involves creating data first-hand by directly working with interviewees, target users, or a target market. Primary research focuses on the method for carrying out research, asking questions, and collecting data using approaches such as:

• Interviews (panel, face-to-face or over the phone)
• Questionnaires or surveys
• Focus groups

Using these methods, researchers can get in-depth, targeted responses to questions, making results more accurate and specific to their research goals. However, it does take time to do and administer.

Unlike primary research, secondary research uses existing data, which also includes published results from primary research. Researchers summarize the existing research and use the results to support their research goals.

Both primary and secondary research have their places. Primary research can support the findings found through secondary research (and fill knowledge gaps), while secondary research can be a starting point for further primary research. Because of this, these research methods are often combined for optimal research results that are accurate at both the micro and macro level.

Sources of Secondary Research

There are two types of secondary research sources: internal and external. Internal data refers to in-house data that can be gathered from the researcher’s organization. External data refers to data published outside of and not owned by the researcher’s organization.

Internal data

Internal data is a good first port of call for insights and knowledge, as you may already have relevant information stored in your systems. Because you own this information — and it won’t be available to other researchers — it can give you a competitive edge . Examples of internal data include:

• Database information on sales history and business goal conversions
• Information from website applications and mobile site data
• Customer-generated data on product and service efficiency and use
• Previous research results or supplemental research areas
• Previous campaign results

External data

External data is useful when you: 1) need information on a new topic, 2) want to fill in gaps in your knowledge, or 3) want data that breaks down a population or market for trend and pattern analysis. Examples of external data include:

• Government, non-government agencies, and trade body statistics
• Company reports and research
• Competitor research
• Public library collections
• Textbooks and research journals
• Media stories in newspapers
• Online journals and research sites

Three examples of secondary research methods in action

How and why might you conduct secondary research? Let’s look at a few examples:

1.    Collecting factual information from the internet on a specific topic or market

There are plenty of sites that hold data for people to view and use in their research. For example, Google Scholar, ResearchGate, or Wiley Online Library all provide previous research on a particular topic. Researchers can create free accounts and use the search facilities to look into a topic by keyword, before following the instructions to download or export results for further analysis.

This can be useful for exploring a new market that your organization wants to consider entering. For instance, by viewing the U.S Census Bureau demographic data for that area, you can see what the demographics of your target audience are , and create compelling marketing campaigns accordingly.

2.    Finding out the views of your target audience on a particular topic

If you’re interested in seeing the historical views on a particular topic, for example, attitudes to women’s rights in the US, you can turn to secondary sources.

Textbooks, news articles, reviews, and journal entries can all provide qualitative reports and interviews covering how people discussed women’s rights. There may be multimedia elements like video or documented posters of propaganda showing biased language usage.

By gathering this information, synthesizing it, and evaluating the language, who created it and when it was shared, you can create a timeline of how a topic was discussed over time.

3.    When you want to know the latest thinking on a topic

Educational institutions, such as schools and colleges, create a lot of research-based reports on younger audiences or their academic specialisms. Dissertations from students also can be submitted to research journals, making these places useful places to see the latest insights from a new generation of academics.

Information can be requested — and sometimes academic institutions may want to collaborate and conduct research on your behalf. This can provide key primary data in areas that you want to research, as well as secondary data sources for your research.

Advantages of secondary research

There are several benefits of using secondary research, which we’ve outlined below:

• Easily and readily available data – There is an abundance of readily accessible data sources that have been pre-collected for use, in person at local libraries and online using the internet. This data is usually sorted by filters or can be exported into spreadsheet format, meaning that little technical expertise is needed to access and use the data.
• Faster research speeds – Since the data is already published and in the public arena, you don’t need to collect this information through primary research. This can make the research easier to do and faster, as you can get started with the data quickly.
• Low financial and time costs – Most secondary data sources can be accessed for free or at a small cost to the researcher, so the overall research costs are kept low. In addition, by saving on preliminary research, the time costs for the researcher are kept down as well.
• Secondary data can drive additional research actions – The insights gained can support future research activities (like conducting a follow-up survey or specifying future detailed research topics) or help add value to these activities.
• Secondary data can be useful pre-research insights – Secondary source data can provide pre-research insights and information on effects that can help resolve whether research should be conducted. It can also help highlight knowledge gaps, so subsequent research can consider this.
• Ability to scale up results – Secondary sources can include large datasets (like Census data results across several states) so research results can be scaled up quickly using large secondary data sources.

Disadvantages of secondary research

The disadvantages of secondary research are worth considering in advance of conducting research :

• Secondary research data can be out of date – Secondary sources can be updated regularly, but if you’re exploring the data between two updates, the data can be out of date. Researchers will need to consider whether the data available provides the right research coverage dates, so that insights are accurate and timely, or if the data needs to be updated. Also, fast-moving markets may find secondary data expires very quickly.
• Secondary research needs to be verified and interpreted – Where there’s a lot of data from one source, a researcher needs to review and analyze it. The data may need to be verified against other data sets or your hypotheses for accuracy and to ensure you’re using the right data for your research.
• The researcher has had no control over the secondary research – As the researcher has not been involved in the secondary research, invalid data can affect the results. It’s therefore vital that the methodology and controls are closely reviewed so that the data is collected in a systematic and error-free way.
• Secondary research data is not exclusive – As data sets are commonly available, there is no exclusivity and many researchers can use the same data. This can be problematic where researchers want to have exclusive rights over the research results and risk duplication of research in the future.

When do we conduct secondary research?

Now that you know the basics of secondary research, when do researchers normally conduct secondary research?

It’s often used at the beginning of research, when the researcher is trying to understand the current landscape . In addition, if the research area is new to the researcher, it can form crucial background context to help them understand what information exists already. This can plug knowledge gaps, supplement the researcher’s own learning or add to the research.

Secondary research can also be used in conjunction with primary research. Secondary research can become the formative research that helps pinpoint where further primary research is needed to find out specific information. It can also support or verify the findings from primary research.

You can use secondary research where high levels of control aren’t needed by the researcher, but a lot of knowledge on a topic is required from different angles.

Secondary research should not be used in place of primary research as both are very different and are used for various circumstances.

Questions to ask before conducting secondary research

Before you start your secondary research, ask yourself these questions:

• Is there similar internal data that we have created for a similar area in the past?

If your organization has past research, it’s best to review this work before starting a new project. The older work may provide you with the answers, and give you a starting dataset and context of how your organization approached the research before. However, be mindful that the work is probably out of date and view it with that note in mind. Read through and look for where this helps your research goals or where more work is needed.

• What am I trying to achieve with this research?

When you have clear goals, and understand what you need to achieve, you can look for the perfect type of secondary or primary research to support the aims. Different secondary research data will provide you with different information – for example, looking at news stories to tell you a breakdown of your market’s buying patterns won’t be as useful as internal or external data e-commerce and sales data sources.

• How credible will my research be?

If you are looking for credibility, you want to consider how accurate the research results will need to be, and if you can sacrifice credibility for speed by using secondary sources to get you started. Bear in mind which sources you choose — low-credibility data sites, like political party websites that are highly biased to favor their own party, would skew your results.

• What is the date of the secondary research?

When you’re looking to conduct research, you want the results to be as useful as possible , so using data that is 10 years old won’t be as accurate as using data that was created a year ago. Since a lot can change in a few years, note the date of your research and look for earlier data sets that can tell you a more recent picture of results. One caveat to this is using data collected over a long-term period for comparisons with earlier periods, which can tell you about the rate and direction of change.

• Can the data sources be verified? Does the information you have check out?

If you can’t verify the data by looking at the research methodology, speaking to the original team or cross-checking the facts with other research, it could be hard to be sure that the data is accurate. Think about whether you can use another source, or if it’s worth doing some supplementary primary research to replicate and verify results to help with this issue.

Secondary Research: Definition, Methods and Examples.

In the world of research, there are two main types of data sources: primary and secondary. While primary research involves collecting new data directly from individuals or sources, secondary research involves analyzing existing data already collected by someone else. Today we’ll discuss secondary research.

One common source of this research is published research reports and other documents. These materials can often be found in public libraries, on websites, or even as data extracted from previously conducted surveys. In addition, many government and non-government agencies maintain extensive data repositories that can be accessed for research purposes.

LEARN ABOUT: Research Process Steps

While secondary research may not offer the same level of control as primary research, it can be a highly valuable tool for gaining insights and identifying trends. Researchers can save time and resources by leveraging existing data sources while still uncovering important information.

What is Secondary Research: Definition

Secondary research is a research method that involves using already existing data. Existing data is summarized and collated to increase the overall effectiveness of the research.

One of the key advantages of secondary research is that it allows us to gain insights and draw conclusions without having to collect new data ourselves. This can save time and resources and also allow us to build upon existing knowledge and expertise.

When conducting secondary research, it’s important to be thorough and thoughtful in our approach. This means carefully selecting the sources and ensuring that the data we’re analyzing is reliable and relevant to the research question . It also means being critical and analytical in the analysis and recognizing any potential biases or limitations in the data.

LEARN ABOUT: Level of Analysis

Secondary research is much more cost-effective than primary research , as it uses already existing data, unlike primary research, where data is collected firsthand by organizations or businesses or they can employ a third party to collect data on their behalf.

LEARN ABOUT: Data Analytics Projects

Secondary Research Methods with Examples

Secondary research is cost-effective, one of the reasons it is a popular choice among many businesses and organizations. Not every organization is able to pay a huge sum of money to conduct research and gather data. So, rightly secondary research is also termed “ desk research ”, as data can be retrieved from sitting behind a desk.

The following are popularly used secondary research methods and examples:

1. Data Available on The Internet

One of the most popular ways to collect secondary data is the internet. Data is readily available on the internet and can be downloaded at the click of a button.

This data is practically free of cost, or one may have to pay a negligible amount to download the already existing data. Websites have a lot of information that businesses or organizations can use to suit their research needs. However, organizations need to consider only authentic and trusted website to collect information.

2. Government and Non-Government Agencies

Data for secondary research can also be collected from some government and non-government agencies. For example, US Government Printing Office, US Census Bureau, and Small Business Development Centers have valuable and relevant data that businesses or organizations can use.

There is a certain cost applicable to download or use data available with these agencies. Data obtained from these agencies are authentic and trustworthy.

3. Public Libraries

Public libraries are another good source to search for data for this research. Public libraries have copies of important research that were conducted earlier. They are a storehouse of important information and documents from which information can be extracted.

The services provided in these public libraries vary from one library to another. More often, libraries have a huge collection of government publications with market statistics, large collection of business directories and newsletters.

4. Educational Institutions

Importance of collecting data from educational institutions for secondary research is often overlooked. However, more research is conducted in colleges and universities than any other business sector.

The data that is collected by universities is mainly for primary research. However, businesses or organizations can approach educational institutions and request for data from them.

5. Commercial Information Sources

Local newspapers, journals, magazines, radio and TV stations are a great source to obtain data for secondary research. These commercial information sources have first-hand information on economic developments, political agenda, market research, demographic segmentation and similar subjects.

Businesses or organizations can request to obtain data that is most relevant to their study. Businesses not only have the opportunity to identify their prospective clients but can also know about the avenues to promote their products or services through these sources as they have a wider reach.

Key Differences between Primary Research and Secondary Research

Understanding the distinction between primary research and secondary research is essential in determining which research method is best for your project. These are the two main types of research methods, each with advantages and disadvantages. In this section, we will explore the critical differences between the two and when it is appropriate to use them.

How to Conduct Secondary Research?

We have already learned about the differences between primary and secondary research. Now, let’s take a closer look at how to conduct it.

Secondary research is an important tool for gathering information already collected and analyzed by others. It can help us save time and money and allow us to gain insights into the subject we are researching. So, in this section, we will discuss some common methods and tips for conducting it effectively.

Here are the steps involved in conducting secondary research:

1. Identify the topic of research: Before beginning secondary research, identify the topic that needs research. Once that’s done, list down the research attributes and its purpose.

2. Identify research sources: Next, narrow down on the information sources that will provide most relevant data and information applicable to your research.

3. Collect existing data: Once the data collection sources are narrowed down, check for any previous data that is available which is closely related to the topic. Data related to research can be obtained from various sources like newspapers, public libraries, government and non-government agencies etc.

4. Combine and compare: Once data is collected, combine and compare the data for any duplication and assemble data into a usable format. Make sure to collect data from authentic sources. Incorrect data can hamper research severely.

4. Analyze data: Analyze collected data and identify if all questions are answered. If not, repeat the process if there is a need to dwell further into actionable insights.

Advantages of Secondary Research

Secondary research offers a number of advantages to researchers, including efficiency, the ability to build upon existing knowledge, and the ability to conduct research in situations where primary research may not be possible or ethical. By carefully selecting their sources and being thoughtful in their approach, researchers can leverage secondary research to drive impact and advance the field. Some key advantages are the following:

1. Most information in this research is readily available. There are many sources from which relevant data can be collected and used, unlike primary research, where data needs to collect from scratch.

2. This is a less expensive and less time-consuming process as data required is easily available and doesn’t cost much if extracted from authentic sources. A minimum expenditure is associated to obtain data.

3. The data that is collected through secondary research gives organizations or businesses an idea about the effectiveness of primary research. Hence, organizations or businesses can form a hypothesis and evaluate cost of conducting primary research.

4. Secondary research is quicker to conduct because of the availability of data. It can be completed within a few weeks depending on the objective of businesses or scale of data needed.

As we can see, this research is the process of analyzing data already collected by someone else, and it can offer a number of benefits to researchers.

Disadvantages of Secondary Research

On the other hand, we have some disadvantages that come with doing secondary research. Some of the most notorious are the following:

1. Although data is readily available, credibility evaluation must be performed to understand the authenticity of the information available.

2. Not all secondary data resources offer the latest reports and statistics. Even when the data is accurate, it may not be updated enough to accommodate recent timelines.

3. Secondary research derives its conclusion from collective primary research data. The success of your research will depend, to a greater extent, on the quality of research already conducted by primary research.

LEARN ABOUT: 12 Best Tools for Researchers

In conclusion, secondary research is an important tool for researchers exploring various topics. By leveraging existing data sources, researchers can save time and resources, build upon existing knowledge, and conduct research in situations where primary research may not be feasible.

There are a variety of methods and examples of secondary research, from analyzing public data sets to reviewing previously published research papers. As students and aspiring researchers, it’s important to understand the benefits and limitations of this research and to approach it thoughtfully and critically. By doing so, we can continue to advance our understanding of the world around us and contribute to meaningful research that positively impacts society.

Secondary Research Guide: Definition, Methods, Examples

Apr 3, 2024

8 min. read

The internet has vastly expanded our access to information, allowing us to learn almost anything about everything. But not all market research is created equal , and this secondary research guide explains why.

There are two key ways to do research. One is to test your own ideas, make your own observations, and collect your own data to derive conclusions. The other is to use secondary research — where someone else has done most of the heavy lifting for you. 

Here’s an overview of secondary research and the value it brings to data-driven businesses.

Secondary Research Definition: What Is Secondary Research?

Primary vs Secondary Market Research

What Are Secondary Research Methods?

Advantages of secondary research, disadvantages of secondary research, best practices for secondary research, how to conduct secondary research with meltwater.

Secondary research definition: The process of collecting information from existing sources and data that have already been analyzed by others.

Secondary research (aka desk research or complementary research ) provides a foundation to help you understand a topic, with the goal of building on existing knowledge. They often cover the same information as primary sources, but they add a layer of analysis and explanation to them.

Users can choose from several secondary research types and sources, including:

• Journal articles
• Research papers

With secondary sources, users can draw insights, detect trends , and validate findings to jumpstart their research efforts.

Primary vs. Secondary Market Research

We’ve touched a little on primary research , but it’s essential to understand exactly how primary and secondary research are unique.

Think of primary research as the “thing” itself, and secondary research as the analysis of the “thing,” like these primary and secondary research examples:

• An expert gives an interview (primary research) and a marketer uses that interview to write an article (secondary research).
• A company conducts a consumer satisfaction survey (primary research) and a business analyst uses the survey data to write a market trend report (secondary research).
• A marketing team launches a new advertising campaign across various platforms (primary research) and a marketing research firm, like Meltwater for market research , compiles the campaign performance data to benchmark against industry standards (secondary research).

In other words, primary sources make original contributions to a topic or issue, while secondary sources analyze, synthesize, or interpret primary sources.

Both are necessary when optimizing a business, gaining a competitive edge , improving marketing, or understanding consumer trends that may impact your business.

Secondary research methods focus on analyzing existing data rather than collecting primary data . Common examples of secondary research methods include:

• Literature review . Researchers analyze and synthesize existing literature (e.g., white papers, research papers, articles) to find knowledge gaps and build on current findings.
• Content analysis . Researchers review media sources and published content to find meaningful patterns and trends.
• AI-powered secondary research . Platforms like Meltwater for market research analyze vast amounts of complex data and use AI technologies like natural language processing and machine learning to turn data into contextual insights.

Researchers today have access to more secondary research companies and market research tools and technology than ever before, allowing them to streamline their efforts and improve their findings.

Want to see how Meltwater can complement your secondary market research efforts? Simply fill out the form at the bottom of this post, and we'll be in touch.

Conducting secondary research offers benefits in every job function and use case, from marketing to the C-suite. Here are a few advantages you can expect.

Cost and time efficiency

Using existing research saves you time and money compared to conducting primary research. Secondary data is readily available and easily accessible via libraries, free publications, or the Internet. This is particularly advantageous when you face time constraints or when a project requires a large amount of data and research.

Access to large datasets

Secondary data gives you access to larger data sets and sample sizes compared to what primary methods may produce. Larger sample sizes can improve the statistical power of the study and add more credibility to your findings.

Ability to analyze trends and patterns

Using larger sample sizes, researchers have more opportunities to find and analyze trends and patterns. The more data that supports a trend or pattern, the more trustworthy the trend becomes and the more useful for making decisions. 

Historical context

Using a combination of older and recent data allows researchers to gain historical context about patterns and trends. Learning what’s happened before can help decision-makers gain a better current understanding and improve how they approach a problem or project.

Basis for further research

Ideally, you’ll use secondary research to further other efforts . Secondary sources help to identify knowledge gaps, highlight areas for improvement, or conduct deeper investigations.

Tip: Learn how to use Meltwater as a research tool and how Meltwater uses AI.

Secondary research comes with a few drawbacks, though these aren’t necessarily deal breakers when deciding to use secondary sources.

Reliability concerns

Researchers don’t always know where the data comes from or how it’s collected, which can lead to reliability concerns. They don’t control the initial process, nor do they always know the original purpose for collecting the data, both of which can lead to skewed results.

Potential bias

The original data collectors may have a specific agenda when doing their primary research, which may lead to biased findings. Evaluating the credibility and integrity of secondary data sources can prove difficult.

Outdated information

Secondary sources may contain outdated information, especially when dealing with rapidly evolving trends or fields. Using outdated information can lead to inaccurate conclusions and widen knowledge gaps.

Limitations in customization

Relying on secondary data means being at the mercy of what’s already published. It doesn’t consider your specific use cases, which limits you as to how you can customize and use the data.

A lack of relevance

Secondary research rarely holds all the answers you need, at least from a single source. You typically need multiple secondary sources to piece together a narrative, and even then you might not find the specific information you need.

To make secondary market research your new best friend, you’ll need to think critically about its strengths and find ways to overcome its weaknesses. Let’s review some best practices to use secondary research to its fullest potential.

Identify credible sources for secondary research

To overcome the challenges of bias, accuracy, and reliability, choose secondary sources that have a demonstrated history of excellence . For example, an article published in a medical journal naturally has more credibility than a blog post on a little-known website.

Assess credibility based on peer reviews, author expertise, sampling techniques, publication reputation, and data collection methodologies. Cross-reference the data with other sources to gain a general consensus of truth.

The more credibility “factors” a source has, the more confidently you can rely on it. 

Evaluate the quality and relevance of secondary data

You can gauge the quality of the data by asking simple questions:

• How complete is the data? 
• How old is the data? 
• Is this data relevant to my needs?
• Does the data come from a known, trustworthy source?

It’s best to focus on data that aligns with your research objectives. Knowing the questions you want to answer and the outcomes you want to achieve ahead of time helps you focus only on data that offers meaningful insights.

Document your sources 

If you’re sharing secondary data with others, it’s essential to document your sources to gain others’ trust. They don’t have the benefit of being “in the trenches” with you during your research, and sharing your sources can add credibility to your findings and gain instant buy-in.

Secondary market research offers an efficient, cost-effective way to learn more about a topic or trend, providing a comprehensive understanding of the customer journey .

What is Secondary Research? | Definition, Types, & Examples

Published on 20 January 2023 by Tegan George .

Secondary research is a research method that uses data that was collected by someone else. In other words, whenever you conduct research using data that already exists, you are conducting secondary research. On the other hand, any type of research that you undertake yourself is called primary research .

Secondary research can be qualitative or quantitative in nature. It often uses data gathered from published peer-reviewed papers, meta-analyses, or government or private sector databases and datasets.

Table of contents

When to use secondary research, types of secondary research, examples of secondary research, advantages and disadvantages of secondary research, frequently asked questions.

Secondary research is a very common research method, used in lieu of collecting your own primary data. It is often used in research designs or as a way to start your research process if you plan to conduct primary research later on.

Since it is often inexpensive or free to access, secondary research is a low-stakes way to determine if further primary research is needed, as gaps in secondary research are a strong indication that primary research is necessary. For this reason, while secondary research can theoretically be exploratory or explanatory in nature, it is usually explanatory: aiming to explain the causes and consequences of a well-defined problem.

Prevent plagiarism, run a free check.

Secondary research can take many forms, but the most common types are:

Statistical analysis

Literature reviews, case studies, content analysis.

There is ample data available online from a variety of sources, often in the form of datasets. These datasets are often open-source or downloadable at a low cost, and are ideal for conducting statistical analyses such as hypothesis testing or regression analysis .

Credible sources for existing data include:

• The government
• Government agencies
• Non-governmental organizations
• Educational institutions
• Businesses or consultancies
• Libraries or archives
• Newspapers, academic journals, or magazines

A literature review is a survey of preexisting scholarly sources on your topic. It provides an overview of current knowledge, allowing you to identify relevant themes, debates, and gaps in the research you analyse. You can later apply these to your own work, or use them as a jumping-off point to conduct primary research of your own.

Structured much like a regular academic paper (with a clear introduction, body, and conclusion), a literature review is a great way to evaluate the current state of research and demonstrate your knowledge of the scholarly debates around your topic.

A case study is a detailed study of a specific subject. It is usually qualitative in nature and can focus on  a person, group, place, event, organisation, or phenomenon. A case study is a great way to utilise existing research to gain concrete, contextual, and in-depth knowledge about your real-world subject.

You can choose to focus on just one complex case, exploring a single subject in great detail, or examine multiple cases if you’d prefer to compare different aspects of your topic. Preexisting interviews , observational studies , or other sources of primary data make for great case studies.

Content analysis is a research method that studies patterns in recorded communication by utilizing existing texts. It can be either quantitative or qualitative in nature, depending on whether you choose to analyse countable or measurable patterns, or more interpretive ones. Content analysis is popular in communication studies, but it is also widely used in historical analysis, anthropology, and psychology to make more semantic qualitative inferences.

Secondary research is a broad research approach that can be pursued any way you’d like. Here are a few examples of different ways you can use secondary research to explore your research topic .

Secondary research is a very common research approach, but has distinct advantages and disadvantages.

Advantages of secondary research

Advantages include:

• Secondary data is very easy to source and readily available .
• It is also often free or accessible through your educational institution’s library or network, making it much cheaper to conduct than primary research .
• As you are relying on research that already exists, conducting secondary research is much less time consuming than primary research. Since your timeline is so much shorter, your research can be ready to publish sooner.
• Using data from others allows you to show reproducibility and replicability , bolstering prior research and situating your own work within your field.

Disadvantages of secondary research

Disadvantages include:

• Ease of access does not signify credibility . It’s important to be aware that secondary research is not always reliable , and can often be out of date. It’s critical to analyse any data you’re thinking of using prior to getting started, using a method like the CRAAP test .
• Secondary research often relies on primary research already conducted. If this original research is biased in any way, those research biases could creep into the secondary results.

Many researchers using the same secondary research to form similar conclusions can also take away from the uniqueness and reliability of your research. Many datasets become ‘kitchen-sink’ models, where too many variables are added in an attempt to draw increasingly niche conclusions from overused data . Data cleansing may be necessary to test the quality of the research.

A systematic review is secondary research because it uses existing research. You don’t collect new data yourself.

The research methods you use depend on the type of data you need to answer your research question .

• If you want to measure something or test a hypothesis , use quantitative methods . If you want to explore ideas, thoughts, and meanings, use qualitative methods .
• If you want to analyse a large amount of readily available data, use secondary data. If you want data specific to your purposes with control over how they are generated, collect primary data.
• If you want to establish cause-and-effect relationships between variables , use experimental methods. If you want to understand the characteristics of a research subject, use descriptive methods.

Quantitative research deals with numbers and statistics, while qualitative research deals with words and meanings.

Quantitative methods allow you to test a hypothesis by systematically collecting and analysing data, while qualitative methods allow you to explore ideas and experiences in depth.

• Reduced Bias: As data is collected by others, there's often less inherent bias than in conducting primary research, where biases might affect data collection.
• Support for Primary Research: Secondary research can lay the foundation for primary research by providing context and insights into gaps in existing knowledge.
• Comparative Analysis : By integrating data from multiple sources, you can conduct robust comparative analyses for more accurate conclusions.
• Benchmarking and Validation: Secondary research aids in benchmarking performance against industry standards and validating hypotheses.

Primary Research vs. Secondary Research

When it comes to research methodologies, primary and secondary research each have their distinct characteristics and advantages. Here's a brief comparison to help you understand the differences.

Primary Research

• Data Source: Involves collecting new data directly from original sources.
• Data Collection: Researchers design and conduct surveys, interviews, experiments, or observations.
• Time and Resources: Typically requires more time, effort, and resources due to data collection.
• Fresh Insights: Provides firsthand, up-to-date information tailored to specific research questions.
• Control: Researchers control the data collection process and can shape methodologies.

Secondary Research

• Data Source: Involves utilizing existing data and information collected by others.
• Data Collection: Researchers search, select, and analyze data from published sources, reports, and databases.
• Time and Resources: Generally more time-efficient and cost-effective as data is already available.
• Existing Knowledge: Utilizes data that has been previously compiled, often providing broader context.
• Less Control: Researchers have limited control over how data was collected originally, if any.

Choosing between primary and secondary research depends on your research objectives, available resources, and the depth of insights you require.

Types of Secondary Research

Secondary research encompasses various types of existing data sources that can provide valuable insights for your research endeavors. Understanding these types can help you choose the most relevant sources for your objectives.

Here are the primary types of secondary research:

Internal Sources

Internal sources consist of data generated within your organization or entity. These sources provide valuable insights into your own operations and performance.

• Company Records and Data: Internal reports, documents, and databases that house information about sales, operations, and customer interactions.
• Sales Reports and Customer Data: Analysis of past sales trends, customer demographics, and purchasing behavior.
• Financial Statements and Annual Reports: Financial data, such as balance sheets and income statements, offer insights into the organization's financial health.

External Sources

External sources encompass data collected and published by entities outside your organization.

These sources offer a broader perspective on various subjects.

• Published Literature and Journals: Scholarly articles, research papers, and academic studies available in journals or online databases.
• Market Research Reports: Reports from market research firms that provide insights into industry trends, consumer behavior, and market forecasts.
• Government and NGO Databases: Data collected and maintained by government agencies and non-governmental organizations, offering demographic, economic, and social information.
• Online Media and News Articles: News outlets and online publications that cover current events, trends, and societal developments.

Each type of secondary research source holds its value and relevance, depending on the nature of your research objectives. Combining these sources lets you understand the subject matter and make informed decisions.

How to Conduct Secondary Research?

Effective secondary research involves a thoughtful and systematic approach that enables you to extract valuable insights from existing data sources. Here's a step-by-step guide on how to navigate the process:

1. Define Your Research Objectives

Before delving into secondary research, clearly define what you aim to achieve. Identify the specific questions you want to answer, the insights you're seeking, and the scope of your research.

2. Identify Relevant Sources

Begin by identifying the most appropriate sources for your research. Consider the nature of your research objectives and the data type you require. Seek out sources such as academic journals, market research reports, official government databases, and reputable news outlets.

3. Evaluate Source Credibility

Ensuring the credibility of your sources is crucial. Evaluate the reliability of each source by assessing factors such as the author's expertise, the publication's reputation, and the objectivity of the information provided. Choose sources that align with your research goals and are free from bias.

4. Extract and Analyze Information

Once you've gathered your sources, carefully extract the relevant information. Take thorough notes, capturing key data points, insights, and any supporting evidence. As you accumulate information, start identifying patterns, trends, and connections across different sources.

5. Synthesize Findings

As you analyze the data, synthesize your findings to draw meaningful conclusions. Compare and contrast information from various sources to identify common themes and discrepancies. This synthesis process allows you to construct a coherent narrative that addresses your research objectives.

6. Address Limitations and Gaps

Acknowledge the limitations and potential gaps in your secondary research. Recognize that secondary data might have inherent biases or be outdated. Where necessary, address these limitations by cross-referencing information or finding additional sources to fill in gaps.

7. Contextualize Your Findings

Contextualization is crucial in deriving actionable insights from your secondary research. Consider the broader context within which the data was collected. How does the information relate to current trends, societal changes, or industry shifts? This contextual understanding enhances the relevance and applicability of your findings.

8. Cite Your Sources

Maintain academic integrity by properly citing the sources you've used for your secondary research. Accurate citations not only give credit to the original authors but also provide a clear trail for readers to access the information themselves.

9. Integrate Secondary and Primary Research (If Applicable)

In some cases, combining secondary and primary research can yield more robust insights. If you've also conducted primary research, consider integrating your secondary findings with your primary data to provide a well-rounded perspective on your research topic.

You can use a market research platform like Appinio to conduct primary research with real-time insights in minutes!

10. Communicate Your Findings

Finally, communicate your findings effectively. Whether it's in an academic paper, a business report, or any other format, present your insights clearly and concisely. Provide context for your conclusions and use visual aids like charts and graphs to enhance understanding.

Remember that conducting secondary research is not just about gathering information—it's about critically analyzing, interpreting, and deriving valuable insights from existing data. By following these steps, you'll navigate the process successfully and contribute to the body of knowledge in your field.

Secondary Research Examples

To better understand how secondary research is applied in various contexts, let's explore a few real-world examples that showcase its versatility and value.

Defining Secondary Sources

• Secondary sources interpret, analyze, and discuss the evidence provided by primary sources. Examples of secondary sources include scholarly books and articles.
• Secondary sources are generally a second-hand account or observation at least one step removed from the event, i.e., accounts written after the fact by people not present when an event took place. Such sources are second-hand interpretations of what occurred.
• Secondary sources, however, can be considered to be primary sources depending on the context of their use. For example, Ken Burns' documentary of the Civil War is a secondary source for Civil War researchers (because it consists of Burns' interpretation of primary source materials from the Civil War), but a primary source for those studying documentary filmmaking.
• Secondary sources benefit from the filter of time and differing cultural contexts and perspectives which may assist (or interfere with) scholarly analysis.

Secondary sources can include:

• biographical works;
• commentaries and critical reviews;
• books other than fiction or autobiographies
• journal, newspaper, and magazine articles written well after an event takes place

Secondary research, also known as a literature review , preliminary research , historical research , background research , desk research , or library research , is research that analyzes or describes prior research. Rather than generating and analyzing new data, secondary research analyzes existing research results to establish the boundaries of knowledge on a topic, to identify trends or new practices, to test mathematical models or train machine learning systems, or to verify facts and figures. Secondary research is also used to justify the need for primary research as well as to justify and support other activities. For example, secondary research may be used to support a proposal to modernize a manufacturing plant, to justify the use of newly a developed treatment for cancer, to strengthen a business proposal, or to validate points made in a speech.

Because secondary research is used for so many purposes in so many settings, all professionals will be required to perform it at some point in their careers. For managers and entrepreneurs, regardless of the industry or profession, secondary research is a regular part of worklife, although parts of the research, such as finding the supporting documents, are often delegated to juniors in the organization. For all these reasons, it is essential to learn how to conduct secondary research, even if you are unlikely to ever conduct primary research.

Secondary research is also essential if your main goal is primary research. Research funding is obtained only by using secondary research to show the need for the primary research you want to conduct. In fact, primary research depends on secondary research to prove that it is indeed new and original research and not just a rehash or replication of somebody else’s work.

Secondary Sources: ALRs, Encyclopedias, Law Reviews, Restatements, & Treatises

Legal encyclopedias, law review articles, american law reports, restatement drafts, getting help, introduction.

Secondary sources are a great place to begin your research . Although the primary sources of law--case law, statutes, and regulations--establish the law on a given topic, it is often difficult to quickly locate answers in them. Secondary sources often explain legal principles more thoroughly than a single case or statute, so using them can help you save time . Secondary sources also help you avoid unnecessary research, since you're tapping into work that someone else has already done on an issue.

Secondary sources include:

• Legal encyclopedias
• American Law Reports (ALR)
• Law review articles

Restatements

Secondary sources are particularly useful for:

• Learning the basics of a particular area of law
• Understanding key terms of art in an area
• Identifying essential cases and statutes

This guide provides a basic overview of each source, including their strengths and why you might use them, as well as tips on finding, using, and citing them.

This guide is based on material written by Deanna Barmakian.

Intro to Legal Encyclopedias

Legal encyclopedias contain brief, broad summaries of legal topics, providing introductions to legal topics and explaining relevant terms of art.They also provide citations to relevant primary law and sometimes give citations to relevant major law review articles.

There are two main legal encyclopedias in the United States that are national in scope. They are useful, but not well-suited for jurisdiction specific research.

State legal encyclopedias provide background and explanations of state legal topics. Not every state has a legal encyclopedia. Depth of coverage and quality vary. State encyclopedia articles are updated irregularly.

Electronic versions of the encyclopedias are updated directly. If using a print encyclopedia, always remember to check the pocket parts for any updates.

National Legal Encyclopedias

• American Jurisprudence 2d (AmJur) Reading Room KF 154.A42 Am Jur 2d articles summarize broad principles of U.S. law and provide citations to cases, statutes, rules, forms, and A.L.R. annotations. A six-volume general index is located at KF 154.A42. Topical indexes are located in the last volume of every topic.
• American Jurisprudence Available on Lexis
• American Jurisprudence on Westlaw
• Corpus Juris Secundum (CJS) Reading Room KF 154.C56 This 152-volume set is arranged into approximately 400 topics. Articles within topics begin with a general rule of law and are followed by the exceptions and qualifications to that general rule. A four-volume general index is located at KF 154.C56. There are also individual indexes for each major topic.
• Corpus Juris Secundum on Westlaw CJS is not available on Lexis.

State Legal Encyclopedias

Legal encyclopedias are listed alphabetically by state. Electronic versions are included only if they are comprehensive in scope.

For a few states, Westlaw offers a practice series that contains selective coverage of state law, usually covering a few major topics and information useful to litigators. To find them, browse the Westlaw directory by U.S. State Materials > Other U.S. States > State name >  Forms, Treatises, CLEs, and Other Practice Materials, then browse the page for "practice series."

Intro to Treatises

Treatises , not to be confused with treaties , are book-length expositions on the law as it pertains to a particular subject. Treatises may be scholarly in nature, such as Blackstone’s Commentaries on the Law , or they may be geared toward a legal practitioner, such as a manual or handbook.

A legal treatise may be a short, single volume or a large, multivolume set. Many are available electronically as well as in print. Different kinds of treatises have different purposes:

Legal hornbooks are designed as teaching tools for law students. Hornbooks provide more detailed treatments of particular areas of law than an encyclopedia or ALR entry. They generally contain summaries of landmark cases and other useful details.

Nutshells provide an overview of a legal topic without the detailed analysis or extensive case referencing found in other treatises.

Some treatises are designed to serve as practitioners’ tools. These works tend to address realistic legal problems and often provide useful features for practicing lawyers, such as forms and tables.

Looseleaf services are an example of treatises designed to serve as tools for practitioners. Such works address realistic legal problems and often provide useful features for practicing lawyers, such as forms and tables. Looseleaf services are frequently supplemented treatises--hence the looseleaf binder format that enables single pages to be easily updated without republishing the entire volume--that often contain primary legal sources and finding aids in addition to secondary analytical material, making them an invaluable resource if one exists for your topic.

Still other treatises are designed to serve as self-help publications for the public, such as those published by Nolo Press .

Finding treatises

There are several ways to locate legal treatises:

• Use the HLS Library Guide to Legal Treatises by Subject for librarian-recommended treatises in many areas of law
• Do a keyword or subject search in Hollis , Hollis Classic , or another library catalog . Use the expanded search or facets to limit your search to the law school library.
• Ask a research librarian to help you locate treatises on your topic
• Consult reference sources that review treatises by subject such as:

The Legal Information Buyer's Guide and Reference Manual by Ken Svengalis Legal Information: How to Find It, How to Use It by Kent C. Olson (note: this guide does not include single volume works) Legal Looseleafs in Print by Arlene Eis

Using treatises

Using legal treatises is like using any non-law book with a few special advisories.

First, as with any book, use the table of contents and the index to quickly locate relevant sections .

Second, remember that for a publication to provide reliable coverage of contemporary issues, it must be updated regularly and accurately to reflect any changes in the law . Updating may happen through the addition of pocket parts (which are usually tucked in a pocket in the back cover of a volume), by updated pages in a looseleaf, or periodic republication or an entire volume. Researchers should always make sure they are working with the most current edition of the treatise and be sure to consult pocket parts.

Third, while many treatises are still only available in print, more treatises are becoming available online . For example, major treatises on insurance law are available in both Lexis and Westlaw. Electronic versions of treatises allow for full text searching, which can be valuable for research. For more focused search results, consider narrowing your search to relevant sections, if possible. In many cases, you can still access the tables of contents and indexes to help locate chapters or sections of interest.

Remember that you can (and should!) check to see how current the electronic text is by clicking the I link next to the title of the treatise to see how regularly it is updated and when the last update took place.

Intro to Law Review Articles

Law review or journal articles are another great secondary source for legal research, valuable for the depth in which they analyze and critique legal topics, as well as their extensive references to other sources, including primary sources.

Law reviews are scholarly publications, usually edited by law students in conjunction with faculty members. They contain both lengthy articles and shorter essays by professors and lawyers, as well as comments, notes, or developments in the law written by students. Law review articles often focus on new or emerging areas of law and they can offer more critical commentary than a legal encyclopedia or ALR entry .

Some law reviews are dedicated to a particular topic, such as gender and the law or environmental law, and will include in their contents the proceedings of a wide range of panels and symposia on timely legal issues.

Sources of full text law review articles

These resources all provide comprehensive coverage of United States law reviews, and allow you to search the full text of the articles that they index.

• Bloomberg Law Bloomberg Law is available to all HLS students, faculty, and staff. Register with your HLS email address. Law reviews are included in Bloomberg Law's selection of secondary sources.
• HeinOnline Law Journal Library Database of full text, PDF law review articles; use advanced search to search by topic or search specific titles. HeinOnline is the most comprehensive law review articles database, as coverage begins with the first issue of each journal.
• LexisNexis U.S. Law Reviews and Journals, Combined Combined full text database of United States Law Reviews and Bar Journals. Coverage begins in 1982; regular updates as received from publishers. Lexis also contains databases for Canadian law reviews articles and law review articles by jurisdiction and topic.
• Westlaw Journals & Law Reviews Journals and Law Reviews contains full text documents from law reviews and CLE materials from U.S. and Canadian based publications. Coverage varies by publication with most going back to the 1980s or 1990s.

Indexes to law reviews and journals

These resources only index articles, usually by author, title, keywords, and subject; you will have to find the full text separately. However, they provide additional ways of searching, including taking advantage of subject indexing by expert librarians, and they enable finding material that may not be found in full text databases. In most cases, there will be a link to find the article you desire at Harvard. If we do not own the journal in question, you may request the article via interlibrary loan .

• Current Index to Legal Periodicals A weekly publication by the University of Washington Library, CILP indexes the most recent law review and journal publications by subject as well as provides the tables of contents of the journals indexed. Also available on Westlaw and in print in the reference room at K 33 .C86.
• Index to Foreign Legal Periodicals IFLP indexes legal literature worldwide, covering all forms of foreign law, including comparative law and legal systems, such as Islamic law; socialist law; public and private international law; and transnational commercial law.

Also available in print in the reference room at KD 59 .L44.

Working Paper Repositories

Working papers are an additional source of secondary analysis. They are frequently draft or pre-publication versions of law review articles, though you will also find published versions of articles in these databases. When citing or relying on a draft paper, be sure to carefully check its citations and request the author's permission before citing.

• SSRN Legal Scholarship Network Contains both published and working papers by law faculty, as well as scholars working in the fields of accounting, economics, financial economics, and management. Search by author and by title and abstract keywords. Most papers are available for download in pdf format.

Intro to ALR

American Law Reports (frequently abbreviated and referred to as ALR) contains in-depth articles on narrow topics of the law. ALR articles, called annotations, provide background, analysis, and citations to relevant cases, statutes, law review articles, and other annotations .

ALR is published in series:

• two series under its original title Lawyers Reports Annotated
• eight ALR series, one through six
• two federal series

ALR annotations are not jurisdiction specific. Each annotation contains a Table of Jurisdictions to help you find relevant cases within specific states. In the federal series, the Table of Jurisdictions directs you to cases by circuit.

All ALR series continue to be updated, though not on a regular schedule. When using the set in print, always check the pocket parts for updates. ALR is also available in both Lexis and Westlaw, and the electronic versions incorporate updates into the text. ALR annotations can also be completely superceded by more recent annotations. Electronic versions will provide referrals to the superceding annotations, but in print, you should check the History Table at the end of the ALR Index to verify that your annotation has not been superceded.

Find relevant annotations by using the print indices or searching the ALR databases in Lexis or Westlaw. When using ALR electronically, it is most efficient to look for your terms in the titles of the annotations, since their titles are specific, and reflect their contents.

Finding ALR in print and online

• ALR on Westlaw Contains the full text of the annotations included in the First, Second, Third, Fourth, Fifth, Sixth, Federal, and Federal Second series of American Law Reports (ALR) and the Index to Annotations covering these series. Because West publishes ALR, this is the most comprehensive electronic version.

• The ALR Index is located in the Reading Room at KF 132.2.I53. It covers annotations written since 1948.
• The ALR Quick Index is located in the Reading Room at KF 132.6.A543. It covers major annotations from the ALR 3d series to the present.

How to Cite ALR Annotations

See Bluebook Rule 16.6.6

Intro to Restatements

Restatements are highly regarded distillations of common law . They are prepared by the American Law Institute (ALI), a prestigious organization comprising judges, professors, and lawyers. The ALI's aim is to distill the "black letter law" from cases to indicate trends in common law, and occasionally to recommend what a rule of law should be. In essence, they restate existing common law into a series of principles or rules.

Restatements cover broad topics, such as Contracts or Property. They are organized into chapters, titles, and sections. Sections contain a concisely stated rule of law, comments to clarify the rule, hypothetical examples, explanation of purpose, as well as exceptions to the rule.

Restatements are not primary law. Due to the prestige of the ALI and its painstaking drafting process, however, they are considered persuasive authority by many courts. The most heavily cited Restatements are the Restatement of Torts and the Restatement of Contracts.

The ALI web site contains information regarding Restatement projects, ALI membership, history and institutional processes.

Finding Cases Discussing Restatements

Annotations of cases citing a Restatement section can be found in the Appendix volumes the Restatements in print. There may be one or many Appendix volumes. They are organized by Restatement series, (i.e. citations to the first Restatement, then second, etc.), then by section number. Appendices are not cumulative. The spines indicate sections and years covered. They are updated with pocket parts, cumulative annual supplements, and semiannual pamphlets called Interim Case Citations. The same case annotations are available when using the Restatements on LexisNexis or Westlaw.

You can Shepardize a Restatement section on LexisNexis using the following formats. Note that Bluebook citation format for Restatements, or permutations thereof, will not work.

• torts second sec. 46
• property second (donative transfers) sec 25.9
• conflict of laws second sec. 6
• contracts second sec. 35 cmt. d illus. 7

You can also KeyCite a Restatement section on Westlaw using the following formats. Note that KeyCite finds significantly more citing material than Shepard's for Restatements. (See the KeyCite Publications List for additional help with citation format.)

• rest agen s 1
• rest 2d contr s 3
• rest 2d prop-lt s 1.1
• rest 3d trusts-pir s 170

Current Restatements

Listed below are print editions of the Restatements and their locations in the library. Restatements are also available on both Lexis and Westlaw:

Restatements on LexisNexis Rules (along with comments, illustrations, and notes) are searchable in separate sources from case citations. This makes searching for relevant rules very efficient on LexisNexis. Case citations are linked from individual rules. Browse tables of contents or search by keyword. Restatement drafts are in separate sources from final versions of Restatements. The first series of Restatements is not available on LexisNexis.

Retreiving Restatement sections using Get a Document is not intuitive. Search for restatement in the Get a Document Citation Formats list to determine the proper format.

Restatements on Westlaw All series of Restatements are available on Westlaw. Browse tables of contents or search by keyword. Searching the Restatements on Westlaw can be problematic, because multiple series as well as selected drafts are combined into one database along with case citations to all of them, e.g. Torts first, second, and the topic-specialized Torts third series along with citations to all series are in one database. This can make keyword searching inefficient unless you use a fielded search or use the Table of Contents mode to search within a particular Restatement. Examine your search results carefully to ensure you are looking at the current version of a rule. If a rule has been superceded, there will be note above the rule text indicating this.

Retrieving Restatement sections using Find is somewhat intuitive. The format mimics the database ID. See the listed format for KeyCite below; they will also work for Find. For a complete list of Restatement retrieval formats, search the Find Publications List for restatement.

The Drafting Process

For a short overview of the drafting process for a Restatement, see How the ALI Works .

Parties Involved

• ALI Officers: a group of approximately ten, including the Chair of the Council, President, Vice Presidents, Treasurer, Director, and Deputy Directors
• ALI Council: an elected, standing group of approximately sixty judges, professors, and lawyers
• Reporter: Head of the Restatement project appointed by the ALI Officers and Council, responsible for drafting the language of the Restatement
• Advisers: Group of professors and lawyers (usually 12-30 for a Restatement) with subject expertise appointed to advise the Reporter
• Members Consultative Group: Groups of ALI members (usually 50-75 for a Restatement) interested in the topic of a Restatement who wish to offer input
• ALI Membership: a approximately 3000 ALI members who discuss and ocasionally vote on Restatement language at annual meetings; membership gives input only near the end stages of the drafting process

Drafting Process

The following process typically takes between 9 and 21 years:

• A Reporter is appointed by the Council
• The Reporter divides the project into parts that go through the following process separately:
• The Reporter writes a preliminary draft
• The Preliminary draft is sent to the Advisers and the Members Consultative Group
• The Advisers and Members Consultative Group recommend revisions
• The Reporter, at his/her discretion, makes the revisions
• The draft goes back and forth between the Advisers and the Reporter and a series of revised preliminary drafts are made
• The Reporter and Advisers send a council draft to the Council of the Institute
• The Council suggests revisions
• The Reporter is somewhat obliged to make the suggested revisions
• The draft goes back and forth between the Advisors and the Council and a series of council drafts are made
• The Council presents a tentative draft to the ALI membership
• The draft goes back and forth between the Council and the Membership and a series of tentative drafts are made
• Issues surrounding the draft settle and a proposed final draft is usually created
• The proposed final draft (or last tentative draft) is submitted to the ALI Membership at the annual meeting
• The Membership and the Council approve the proposed final draft
• The Restatement is adopted and promulgated and the official text of the Restatement is published

Other ALI-authored works, such as Uniform Commercial Code articles, are created in a similar process. If you want assistance locating materials relating to non-Restatement ALI projects, please ask a research librarian .

TRACING THE HISTORY AND DEVELOPMENT OF RESTATEMENT SECTIONS

Legal researchers sometimes need to trace the historical development of a Restatement section, the impetus for its inclusion, which section of a prior Restatement it derived from, or how it came to be worded a certain way.

For many sections, Reporter's notes explain the development of a section, often explaining earlier versions and citations to cases that were used as the basis for the rule. Reporters notes can be found in the Appendix volumes of individual Restatements.

To trace how the text changed during the drafting process, you can compare various drafts: the tentative drafts, council drafts, preliminary drafts and proposed final drafts. Each draft has its own record in the library catalog. Use the Title Keywords search in  Hollis Classic --for example, search  restatement torts --to locate them. Drafts are also available in the microform set Archive Publications described below.

Some Restatement volumes contain conversion tables. These tables indicate where sections of drafts or sections from earlier series were included in the final, adopted version of a Restatement.

Although some Restatements are designated 2d or 3d, there are not always antecedents. For instance, the Restatement of the Law Governing Lawyers is a Restatement of the Law Third, but there has never been a first or second Restatement of the Law Governing Lawyers.

• The Proceedings of the Annual Meeting of the American Law Institute Available online from 1997 Available on Westlaw from 2000 For additional and older material, see: Reading Room KF 294 .A5 A3 Microform Room Drawer 812 An excellent research tool for those tracing the development of a Restatement section. The ALI has published the Proceedings annually since 1923, except for 1945-1955. The Proceedings contain reports to ALI members, Reporter presentations, transcripts of discussions of drafts, the text of proposed amendments, and include an index of sections discussed. For the years 1945-1955, the Proceedings are only available in the Archive Publications set described below.
• The ALI Reporter Available online from 1999 Reading Room KF 200 .A455 The ALI's quarterly newsletter contains the latest information about ALI projects, meetings, and members, including reports on actions taken on drafts and the full text of chapters approved for discussion at the annual meeting with revisions explained.
• Archive Publications Microfilm Room KF 294.A5 A43, Drawers 963-965 A microfiche set containing the text of of Restatements, all drafts, and ALI Proceedings from annual meetings for the years that were not officially published, 1945-55. It also contains drafts of four Restatement projects that were terminated before completion. The set is arranged by Restatement, by section, and chronologically. Coverage starts with the founding of the ALI in 1923. All drafts produced for ALI projects are added to this set a few years after the project is completed or terminated. There is a print guide to this microfiche collection in the Microform Room at KF 294 .A5 A43.
• American Law Institute Archives Finally, there is a well-indexed, comprehensive collection of the American Law Institute Archives at the Biddle Law Library of the University of Pennsylvania. The archive contains drafts, comments, and correspondence related to ALI projects.

Determining the Current Status of Restatement Drafts

The American Law Institute is continually working on Restatements and other projects. Researchers are often interested in determining whether a Restatement has become final, or what stage the drafting process has reached. The following tools can help answer those questions, as well as provide a history of the development of ALI projects.

• ALI Catalog of Publications The catalog contains information about draft content and authorship. It mentions which portions of Restatements are superceded or in development.
• Annual Report of the ALI Director The Annual Report summarizes work contemplated, underway, and completed during the year on various Restatements. Available online from 1999. Reports 1988-1998, are available in the Reading Room KF 294 .A5 A14 .
• Proceedings of ALI Annual Meetings The Proceedings contain proposed amendments, an index of sections discussed, and records of discussions. Meetings take place in May and the Proceedings are usually available by March or April of the following year. Available online from 1997 Available on Westlaw from 2000 For additional and older material, see: Reading Room KF 294 .A5 A3 Microform Room Drawer 812

Examples of Primary and Secondary Sources in Research

Julia McCoy

Imagine you’re a detective, piecing together clues from a mysterious event. Your leads? These are examples of primary and secondary sources .

In one hand, you hold an original letter penned by the suspect — that’s your primary source. It offers first-hand insights but also bears the author’s biases.

Then you have a newspaper article about the event – this is your secondary source. While it interprets information for you, it may not present every perspective.

Understanding these differences is key to effective research and writing.

This guide will help you decipher between these two types of sources, using practical examples along with tips on when and how best to use them in writing.

Table of Contents:

Primary sources vs. secondary sources, diaries and personal journals, letters and correspondence, official documents, original research reports, oral history interviews, photographs, creative works, autobiographies, eyewitness accounts, a range of secondary sources, the newspaper dilemma, books about events, academic critiques, documentary films, scholarly articles, a direct connection to the past, unfiltered, original content, drawing personal connections, promotes authenticity, fosters critical thinking, rewards curiosity with authenticity, serves multiple purposes in research, depth and diversity, provides context, evidence and support, wide range of sources, critical analysis, avoiding plagiarism, cross-referencing, legal and ethical considerations, documentaries, reviews and essays, newspaper articles, identify your research question or topic, locate relevant primary sources, evaluate authenticity and reliability, contextualize your sources, extract relevant information, analyze and interpret, integrate primary sources seamlessly, use quotations sparingly, create a bibliography or works cited page, provide proper attribution, cite properly, balance with secondary sources, locate relevant secondary sources, evaluate the quality of secondary sources, read and summarize, analyze and synthesize, maintain a critical stance, provide context and analysis, avoid plagiarism.

If you’re investigating an unfamiliar subject or doing research, it’s essential to use both primary and secondary sources. But what’s the difference? And why does it matter?

A primary source, to start with, gives first-hand information about an event, person, object, or work of art. It is typically created during the time under study by those who experienced the events being documented.

Primary sources include diaries recounting personal experiences in war zones or recordings of live concerts — raw data that hasn’t been processed yet.

Meanwhile, secondary sources provide interpretations and analyses based on primary sources. They are one step removed from these original accounts.

An example would be a biography about Beethoven which uses his letters (primary source) as references for insights into his life and work.

In essence, if we were detectives investigating a case, our primary source would be direct evidence like DNA samples, while secondary sources might include crime scene analysis reports. Both are vital but serve different purposes.

While this might seem straightforward at first glance, using them effectively requires skillful balance and understanding.

Examples of primary and secondary sources

Primary Source Examples

If you’re delving into research, primary sources are your first stop. They offer an unfiltered look at the subject matter, be it historical events or scientific discoveries. Here’s a glimpse of some types of primary sources.

A person’s intimate thoughts about their experiences can provide unparalleled insights.

For example, Anne Frank’s diary is a primary source documenting her life in hiding during the Nazi occupation in World War II.

The National Archives Catalog is filled with these types of firsthand accounts from different eras.

Personal letters, emails, or postcards exchanged between individuals can provide insight into historical events or personal relationships.

The words straight from the horse’s mouth — speeches by politicians or interviews with key figures — give us direct access to their views and opinions on matters they were part of.

Transcripts or recordings of speeches given by famous individuals are primary sources for understanding their ideas and influence.

Government documents, such as birth certificates, marriage licenses, passports, and treaties, are primary sources. 

For instance, the U.S. Declaration of Independence is an official document.

PubMed Central (PMC) houses millions of full-text biomedical literature articles, which are excellent examples of original research reports in medicine and life sciences.

Recorded interviews with individuals who lived through particular events or periods serve as primary sources. These can include eyewitness accounts.

Physical objects like clothing, tools, weapons, and archaeological findings are primary sources when studying cultures or historical periods.

Original photographs taken during a specific period can be primary sources. For example, photographs from the American Civil Rights Movement are primary sources that capture historical moments.

Poems, plays, novels, music pieces – these creative works reflect the author’s own imagination but also often draw upon their real-life experiences, making them valuable as primary sources, too.

Personal autobiographies and memoirs provide firsthand accounts of a person’s life and experiences.

In a digital age where everyone has a smartphone camera ready to capture happenings around them, live events or videos posted online serve as eyewitness accounts that are invaluable when investigating contemporary issues.

Now we’ve looked at various forms of primary sources, let me share an example of how an author might use primary sources to write a book on 20th-century pop culture. 

Imagine our author is writing a book about The Beatles. They might use transcripts from John Lennon’s interviews as a primary source. This would allow them to capture Lennon’s perspective on the band’s journey, their creative process, and what they stood for. These transcripts would be more than just information, but rather a peek into John’s mind during those times — raw, unfiltered insights that no secondary source could provide with such authenticity. 

So when you’re embarking on your next research project or simply want to learn more about a particular topic, start by looking at the primary sources available. They’re not just resources; they’re time capsules giving us an undiluted view of past events and people’s experiences.

Secondary Source Examples

Understanding secondary sources is essential for any research. Let’s use a classic scenario as an example: the tale of Little Red Riding Hood.

If you read the original Grimm Brothers’ story, that would be a primary source. But if you picked up a book discussing themes in fairy tales, that would be considered a secondary source.

Different fields have their own unique types of secondary sources. For instance:

• In history and literature studies, books providing analysis or interpretation are common secondary sources.
• In science and medicine, review articles summarizing multiple primary studies fall into this category.
• In law and political sciences, legal commentaries that offer interpretations of statutes or cases serve as examples of secondary resources.

Sometimes classifying documents can get tricky. Take newspapers, for example — they might seem like primary materials because they’re published immediately after events occur. But journalists usually aren’t direct witnesses to every event they cover; instead, they gather information from others.

Newspaper and online news articles that provide information and analysis of current events are considered secondary sources.

We often think all books are prime examples of secondary sources since most authors don’t directly experience what they’re writing about — especially when we talk about historical or scientific topics.

For instance, a history book discussing the causes of World War I is a secondary source.

Biographies, dictionaries , encyclopedias , and textbooks also count as secondary sources since they’re based on other original documents or firsthand accounts.

A critique of a novel, a movie review, or an article analyzing a research study are more examples of secondary sources. They provide analysis but aren’t the primary material themselves. Next time you read your favorite critic’s take on that latest blockbuster film, remember it’s another instance of a secondary source.

While they may include primary source footage, documentary films typically present an edited and interpreted view of historical events or issues.

Peer-reviewed academic journals that summarize, critique, or build upon existing research are secondary sources. Researchers use these to stay up-to-date with current scholarship.

A scholarly article, also known as a research or academic article, is a publication written by experts in a particular field. Journal articles typically present original research findings or analyses from studies conducted by the authors themselves.

In contrast to raw data collected for scientific experiments (which are primary sources), scholarly journal articles serve to interpret this information.

Here’s how you can easily identify examples of primary and secondary sources :

Benefits of Using Primary Sources

If you’ve ever had a burning question and decided to dig deeper for the answer, then you have likely encountered primary sources. But what makes these resources so valuable?

Primary sources offer a first-hand account or direct evidence about an event, object, person, or work of art. They are usually created by witnesses who experienced the events themselves. This provides an unparalleled perspective on historical events that secondary sources simply can’t match.

Primary sources allow writers to dig into the heart of events. They offer unfiltered access to information from its origin point — like reading an original letter by Abraham Lincoln , for instance. This rawness gives readers insight into the context that secondary sources may overlook.

An original letter written by Abraham Lincoln is considered a primary source .

A personal diary entry from World War II has more emotional impact than a textbook summarizing those years does. Primary data helps establish deeper connections between past experiences and current realities because they engage us on a more personal, emotional level.

Another advantage is credibility: when writers base their claims on direct evidence instead of relying on interpretations made by other authors through secondary source material, this makes them appear more authentic and reliable.

Using primary sources encourages critical thinking skills. It requires readers to analyze information from multiple viewpoints, interpret meanings, and make connections with other knowledge they possess. It essentially turns them into mini-historians.

In contrast to textbooks or summarized articles, primary sources present raw data as it was initially recorded — be it letters from soldiers during the American Civil War, photographs capturing key moments from the Great Depression, or audio recordings of Martin Luther King’s famous speeches. Their authenticity sparks curiosity while offering rich detail.

Beyond just providing factual details about an event, primary documents give insight into how people thought and felt at that time — helping researchers understand the cultural context better than any secondary source could do.

Remember: using such powerful tools responsibly is crucial; we must always approach them with an open mind, acknowledging their limitations and biases. But when used effectively, primary sources can be a treasure trove of knowledge that opens doors to new understanding and sparks deeper connections with the past.

Benefits of Using Secondary Sources

There are many advantages of citing secondary sources in your writing.

Secondary sources give your writing depth. They help you present a more rounded view by incorporating different perspectives on the topic. You can also get insights from experts, which add credibility to your arguments.

Some topics require a wide range of data or historical context that may not be feasible to collect firsthand. Secondary sources often provide this breadth of coverage.

Secondary sources can provide valuable context and background information on a topic. This helps your readers better understand the subject matter, especially if it’s complex or unfamiliar to them.

The use of secondary sources allows you to back up claims or ideas with evidence. This is especially useful when dealing with controversial subjects that require support for clarity and persuasiveness.

Well-established secondary sources such as peer-reviewed articles, books, and reputable websites often have a higher level of credibility compared to personal anecdotes or unsupported claims. This can enhance the reliability of your writing.

A biography — such as a book about Lincoln’s life — is a good example of a secondary source.

You can also use secondary sources to support and strengthen your arguments. By citing expert opinions, statistics, or relevant studies, you add weight to your claims and make your writing more persuasive.

Secondary sources encompass various formats such as academic journals, books, essays, documentaries, and news articles — each one offering a unique angle on a subject matter. This diversity enables you to draw information from different mediums to enrich your writing and provide readers with an engaging mix that keeps them hooked while learning.

Conducting primary research, such as surveys or interviews, can be time-consuming. Secondary sources allow you to access data and information that others have already gathered, saving you time and resources.

By cutting down long hours spent on data collection and interpretation, you can focus more on presenting compelling narratives in your writing.

Secondary sources often undergo rigorous review and scrutiny, which means they have been evaluated for their quality and validity. This allows you to engage in critical analysis and evaluation of the information you’re using.

Including expert commentary via secondary sources lets readers see various interpretations or criticisms about the topic at hand, making them think critically too.

Sometimes primary resources may leave gaps; there might be missing information or unexplained events. Secondary sources fill in these blanks and provide a fuller understanding.

Proper in-text citations of secondary sources serve as plagiarism checkers. By giving credit to the original authors of your data, you demonstrate academic integrity.

Secondary sources can lead you to other relevant sources. When you’re reading one secondary source, you may discover citations or references to additional materials that deepen your understanding of the subject.

In some cases, using secondary sources can help you navigate legal and ethical considerations, especially when dealing with sensitive topics or proprietary information.

However, it’s important to use secondary sources judiciously. Always evaluate the quality and reliability of the sources you choose, and be aware of potential biases.

Remember: a good mix of primary and secondary sources makes for well-rounded, compelling content. Balance secondary sources with primary research when appropriate, as primary sources can offer unique insights and original data that secondary sources may lack.

Examples of Primary and Secondary Sources in Different Contexts

The categorization of a source as primary or secondary can sometimes depend on the context of its use. For instance, a personal letter might be a primary source for a historian studying a specific individual but a secondary source for someone researching the historical context of the time. The distinction is not always rigid and can vary depending on the research question and purpose.

A secondary source can become a primary source based on your research question. If the individual, context, or method that created the source is the primary focus of your research, it becomes a primary source.

Here are examples of sources that can be primary or secondary.

If you are researching the causes of World War II, a recent documentary about it would be considered as a secondary source. However, if your focus shifts to filmmaking techniques used in historical documentaries instead, that same documentary becomes a primary source.

Another example involves literary studies. If your paper revolves around the work of Virginia Woolf, then any magazine review critiquing her work is categorized as a secondary resource. But suppose you’re studying critical reception towards her works; in that case, the review transforms into a primary resource.

A newspaper article discussing new economic policy falls under secondary resources when analyzing government policies. However, if we analyze how media covers economic issues, the same article becomes a primary resource.

As you can see, context is everything when it comes to classifying sources as primary or secondary. It all boils down to your research question and what you are trying to investigate.

When to use primary sources and secondary sources

How to Use Primary Sources in Writing

The use of primary sources can elevate your writing, giving it a level of authenticity and depth that secondary sources might not be able to provide. When you directly quote or reference firsthand documents, interviews, experiments, or original artworks, you are making sure your work is rooted in reality.

Here are a few tips on how to effectively use primary sources.

Before diving into primary sources, clearly define your research question or topic. What specific aspect are you investigating, and what information are you seeking?

Determine where and how to find primary sources related to your topic. These sources can include letters, diaries, photographs, official documents, interview transcripts, artifacts, and more.

• Libraries, archives, museums, historical societies, and digital repositories are common places to find primary sources. 
• Online databases and collections can also be valuable resources.

Assess the authenticity and reliability of your chosen primary sources. Consider the source’s origin, creator, date, and purpose. Ensure that the source is credible and relevant to your research.

Understand the historical or cultural context in which the primary sources were created. This background knowledge will help you interpret and analyze the sources accurately.

Extract the pertinent information or data from your primary sources. This may involve transcribing handwritten documents, summarizing interviews, or digitizing materials as needed.

Analyze the primary sources critically. Look for patterns, themes, contradictions, or significant details within the sources. Consider the biases or perspectives of the creators.

Connect the information from your primary sources to your research papers or thesis statement. How does each source contribute to your understanding of the topic?

Incorporate primary sources into your writing smoothly. Avoid merely dropping them into your text without explanation. Provide context and analysis to help your readers understand their relevance.

Use direct quotations from primary sources sparingly. It’s often more effective to paraphrase or summarize the content of the source in your own words, with appropriate citations.

Include a bibliography or works cited page at the end of your writing to list all the primary sources you used. Follow guidelines for appropriate citation formats.

Acknowledge the sources of your primary materials and give credit to their creators or owners. This demonstrates academic integrity and respects intellectual property rights.

When citing sources in your writing, follow the appropriate citation style. Popular citation styles include APA style, MLA style, or CMOS style. Include all necessary information, such as the source’s title, creator, date, and location.

Provide context within your text to explain the significance of the primary source and how it supports your argument or narrative.

Always check with your editor, teacher, or professor about what  citation style  to use

While primary sources provide valuable firsthand information, balance them with secondary sources to provide context, analysis, and expert opinions that support and complement your argument.

Remember that using primary sources effectively requires careful research, analysis, and citation. When done well, they can make your writing more compelling, original, and authoritative.

How to Use Secondary Sources in Writing

When it comes to writing, secondary sources are essential for adding depth and credibility. They offer an interpretation or analysis of primary source data and give your work depth and credibility. But how can you effectively use these resources?

Identify secondary sources that are relevant to your research. These can include books, scholarly articles, reports, reviews, and reputable websites. 

Use academic databases, library catalogs, and search engines to find these sources.

Assess the credibility and reliability of your chosen secondary sources. Consider the author’s qualifications, the publication source, peer-review status (for academic articles), and the date of publication. 

Aim to include sources from respected and authoritative authors or institutions.

Always cross-reference different secondary sources to avoid bias or misinterpretation.

Carefully read the secondary sources and summarize their main points, arguments, evidence, and conclusions. Note any key quotes or data that you may want to reference in your writing.

Analyze the secondary sources critically. Evaluate the author’s methodology, evidence, and arguments. Consider any biases or limitations in the source.

Synthesize the information from multiple secondary sources to identify common themes, conflicting viewpoints, or gaps in the existing literature. This will help you form a well-rounded understanding of your topic.

While secondary sources provide valuable insights, maintain a critical stance and be prepared to engage with differing viewpoints or critiques of the sources you reference.

When introducing secondary sources, provide context for your readers. Explain the significance of each source and how it relates to your research question or thesis.

Offer critical analysis of the secondary sources you reference. Discuss their strengths, weaknesses, and contributions to the overall understanding of your topic.

Properly attribute all ideas, information, and quotations from secondary sources. Plagiarism is a serious academic offense, so be sure to use quotation marks and cite sources accurately.

Use citations to attribute information, ideas, or quotes to the original sources.

Choose an appropriate citation style (e.g., APA, MLA, Chicago) to cite secondary sources in your writing.

Secondary sources can enhance the depth and credibility of your writing, as they provide context, analysis, and expert perspectives.

Always remember: they serve primarily as interpretive guides rather than factual accounts themselves.

These examples of primary and secondary sources are your detective tools in research. They help you piece together the full story.

Primary sources give you raw, first-hand data but may come with their author’s biases.

Secondary sources offer interpretation but may not cover all perspectives.

In writing or research, both have their place and benefits. The key is knowing when to use each for maximum impact.

To become a master researcher or writer, practice using these resources effectively — just like any skilled detective would do!

Frequently asked questions

What are some examples of secondary sources.

Common examples of secondary sources include academic books, journal articles , reviews, essays , and textbooks.

Anything that summarizes, evaluates or interprets primary sources can be a secondary source. If a source gives you an overview of background information or presents another researcher’s ideas on your topic, it is probably a secondary source.

Frequently asked questions: Citing sources

A scientific citation style is a system of source citation that is used in scientific disciplines. Some commonly used scientific citation styles are:

• Chicago author-date , CSE , and Harvard , used across various sciences
• ACS , used in chemistry
• AMA , NLM , and Vancouver , used in medicine and related disciplines
• AAA , APA , and ASA , commonly used in the social sciences

There are many different citation styles used across different academic disciplines, but they fall into three basic approaches to citation:

• Parenthetical citations : Including identifying details of the source in parentheses —usually the author’s last name and the publication date, plus a page number if available ( author-date ). The publication date is occasionally omitted ( author-page ).
• Numerical citations: Including a number in brackets or superscript, corresponding to an entry in your numbered reference list.
• Note citations: Including a full citation in a footnote or endnote , which is indicated in the text with a superscript number or symbol.

A source annotation in an annotated bibliography fulfills a similar purpose to an abstract : they’re both intended to summarize the approach and key points of a source.

However, an annotation may also evaluate the source , discussing the validity and effectiveness of its arguments. Even if your annotation is purely descriptive , you may have a different perspective on the source from the author and highlight different key points.

You should never just copy text from the abstract for your annotation, as doing so constitutes plagiarism .

Most academics agree that you shouldn’t cite Wikipedia as a source in your academic writing , and universities often have rules against doing so.

This is partly because of concerns about its reliability, and partly because it’s a tertiary source. Tertiary sources are things like encyclopedias and databases that collect information from other sources rather than presenting their own evidence or analysis. Usually, only primary and secondary sources are cited in academic papers.

A Wikipedia citation usually includes the title of the article, “Wikipedia” and/or “Wikimedia Foundation,” the date the article was last updated, and the URL.

In APA Style , you’ll give the URL of the current revision of the article so that you’re sure the reader accesses the same version as you.

There’s some disagreement about whether Wikipedia can be considered a reliable source . Because it can be edited by anyone, many people argue that it’s easy for misleading information to be added to an article without the reader knowing.

Others argue that because Wikipedia articles cite their sources , and because they are worked on by so many editors, misinformation is generally removed quickly.

However, most universities state that you shouldn’t cite Wikipedia in your writing.

Hanging indents are used in reference lists in various citation styles to allow the reader to easily distinguish between entries.

You should apply a hanging indent to your reference entries in APA , MLA , and Chicago style.

A hanging indent is used to indent all lines of a paragraph except the first.

When you create a hanging indent, the first line of the paragraph starts at the border. Each subsequent line is indented 0.5 inches (1.27 cm).

APA and MLA style both use parenthetical in-text citations to cite sources and include a full list of references at the end, but they differ in other ways:

• APA in-text citations include the author name, date, and page number (Taylor, 2018, p. 23), while MLA in-text citations include only the author name and page number (Taylor 23).
• The APA reference list is titled “References,” while MLA’s version is called “ Works Cited .”
• The reference entries differ in terms of formatting and order of information.
• APA requires a title page , while MLA requires a header instead.

A parenthetical citation in Chicago author-date style includes the author’s last name, the publication date, and, if applicable, the relevant page number or page range in parentheses . Include a comma after the year, but not after the author’s name.

For example: (Swan 2003, 6)

To automatically generate accurate Chicago references, you can use Scribbr’s free Chicago reference generator .

APA Style distinguishes between parenthetical and narrative citations.

In parenthetical citations , you include all relevant source information in parentheses at the end of the sentence or clause: “Parts of the human body reflect the principles of tensegrity (Levin, 2002).”

In narrative citations , you include the author’s name in the text itself, followed by the publication date in parentheses: “Levin (2002) argues that parts of the human body reflect the principles of tensegrity.”

In a parenthetical citation in MLA style , include the author’s last name and the relevant page number or range in parentheses .

For example: (Eliot 21)

A parenthetical citation gives credit in parentheses to a source that you’re quoting or paraphrasing . It provides relevant information such as the author’s name, the publication date, and the page number(s) cited.

How you use parenthetical citations will depend on your chosen citation style . It will also depend on the type of source you are citing and the number of authors.

APA does not permit the use of ibid. This is because APA in-text citations are parenthetical and there’s no need to shorten them further.

Ibid. may be used in Chicago footnotes or endnotes .

Write “Ibid.” alone when you are citing the same page number and source as the previous citation.

When you are citing the same source, but a different page number, use ibid. followed by a comma and the relevant page number(s). For example:

• Ibid., 40–42.

Only use ibid . if you are directing the reader to a previous full citation of a source .

Ibid. only refers to the previous citation. Therefore, you should only use ibid. directly after a citation that you want to repeat.

Ibid. is an abbreviation of the Latin “ibidem,” meaning “in the same place.” Ibid. is used in citations to direct the reader to the previous source.

Signal phrases can be used in various ways and can be placed at the beginning, middle, or end of a sentence.

To use signal phrases effectively, include:

• The name of the scholar(s) or study you’re referencing
• An attributive tag such as “according to” or “argues that”
• The quote or idea you want to include

Different citation styles require you to use specific verb tenses when using signal phrases.

• APA Style requires you to use the past or present perfect tense when using signal phrases.
• MLA and Chicago requires you to use the present tense when using signal phrases.

Signal phrases allow you to give credit for an idea or quote to its author or originator. This helps you to:

• Establish the credentials of your sources
• Display your depth of reading and understanding of the field
• Position your own work in relation to other scholars
• Avoid plagiarism

A signal phrase is a group of words that ascribes a quote or idea to an outside source.

Signal phrases distinguish the cited idea or argument from your own writing and introduce important information including the source of the material that you are quoting , paraphrasing , or summarizing . For example:

“ Cognitive psychologist Steven Pinker (1994) insists that humans possess an innate faculty for comprehending grammar.”

If you’re quoting from a text that paraphrases or summarizes other sources and cites them in parentheses , APA and Chicago both recommend retaining the citations as part of the quote. However, MLA recommends omitting citations within a quote:

• APA: Smith states that “the literature on this topic (Jones, 2015; Sill, 2019; Paulson, 2020) shows no clear consensus” (Smith, 2019, p. 4).
• MLA: Smith states that “the literature on this topic shows no clear consensus” (Smith, 2019, p. 4).

Footnote or endnote numbers that appear within quoted text should be omitted in all styles.

If you want to cite an indirect source (one you’ve only seen quoted in another source), either locate the original source or use the phrase “as cited in” in your citation.

In scientific subjects, the information itself is more important than how it was expressed, so quoting should generally be kept to a minimum. In the arts and humanities, however, well-chosen quotes are often essential to a good paper.

In social sciences, it varies. If your research is mainly quantitative , you won’t include many quotes, but if it’s more qualitative , you may need to quote from the data you collected .

As a general guideline, quotes should take up no more than 5–10% of your paper. If in doubt, check with your instructor or supervisor how much quoting is appropriate in your field.

To present information from other sources in academic writing , it’s best to paraphrase in most cases. This shows that you’ve understood the ideas you’re discussing and incorporates them into your text smoothly.

It’s appropriate to quote when:

• Changing the phrasing would distort the meaning of the original text
• You want to discuss the author’s language choices (e.g., in literary analysis )
• You’re presenting a precise definition
• You’re looking in depth at a specific claim

To paraphrase effectively, don’t just take the original sentence and swap out some of the words for synonyms. Instead, try:

• Reformulating the sentence (e.g., change active to passive , or start from a different point)
• Combining information from multiple sentences into one
• Leaving out information from the original that isn’t relevant to your point
• Using synonyms where they don’t distort the meaning

The main point is to ensure you don’t just copy the structure of the original text, but instead reformulate the idea in your own words.

“ Et al. ” is an abbreviation of the Latin term “et alia,” which means “and others.” It’s used in source citations to save space when there are too many authors to name them all.

Guidelines for using “et al.” differ depending on the citation style you’re following:

To insert endnotes in Microsoft Word, follow the steps below:

• Click on the spot in the text where you want the endnote to show up.
• In the “References” tab at the top, select “Insert Endnote.”
• Type whatever text you want into the endnote.

If you need to change the type of notes used in a Word document from footnotes to endnotes , or the other way around, follow these steps:

• Open the “References” tab, and click the arrow in the bottom-right corner of the “Footnotes” section.
• In the pop-up window, click on “Convert…”
• Choose the option you need, and click “OK.”

To insert a footnote automatically in a Word document:

• Click on the point in the text where the footnote should appear
• Select the “References” tab at the top and then click on “Insert Footnote”
• Type the text you want into the footnote that appears at the bottom of the page

Footnotes are notes indicated in your text with numbers and placed at the bottom of the page. They’re used to provide:

• Citations (e.g., in Chicago notes and bibliography )
• Additional information that would disrupt the flow of the main text

Be sparing in your use of footnotes (other than citation footnotes), and consider whether the information you’re adding is relevant for the reader.

Footnotes appear at the bottom of the page they refer to. This is convenient for the reader but may cause your text to look cluttered if there are a lot of footnotes.

Endnotes appear all together at the end of the whole text. This may be less convenient for the reader but reduces clutter.

Both footnotes and endnotes are used in the same way: to cite sources or add extra information. You should usually choose one or the other to use in your text, not both.

An in-text citation is an acknowledgement you include in your text whenever you quote or paraphrase a source. It usually gives the author’s last name, the year of publication, and the page number of the relevant text. In-text citations allow the reader to look up the full source information in your reference list and see your sources for themselves.

If you are reusing content or data you used in a previous assignment, make sure to cite yourself. You can cite yourself just as you would cite any other source: simply follow the directions for that source type in the citation style you are using.

Keep in mind that reusing your previous work can be considered self-plagiarism , so make sure you ask your professor or consult your university’s handbook before doing so.

A credible source should pass the CRAAP test  and follow these guidelines:

• The information should be up to date and current.
• The author and publication should be a trusted authority on the subject you are researching.
• The sources the author cited should be easy to find, clear, and unbiased.
• For a web source, the URL and layout should signify that it is trustworthy.

Peer review is a process of evaluating submissions to an academic journal. Utilizing rigorous criteria, a panel of reviewers in the same subject area decide whether to accept each submission for publication. For this reason, academic journals are often considered among the most credible sources you can use in a research project– provided that the journal itself is trustworthy and well-regarded.

Academic dishonesty can be intentional or unintentional, ranging from something as simple as claiming to have read something you didn’t to copying your neighbor’s answers on an exam.

You can commit academic dishonesty with the best of intentions, such as helping a friend cheat on a paper. Severe academic dishonesty can include buying a pre-written essay or the answers to a multiple-choice test, or falsifying a medical emergency to avoid taking a final exam.

Academic dishonesty refers to deceitful or misleading behavior in an academic setting. Academic dishonesty can occur intentionally or unintentionally, and varies in severity.

It can encompass paying for a pre-written essay, cheating on an exam, or committing plagiarism . It can also include helping others cheat, copying a friend’s homework answers, or even pretending to be sick to miss an exam.

Academic dishonesty doesn’t just occur in a classroom setting, but also in research and other academic-adjacent fields.

To apply a hanging indent to your reference list or Works Cited list in Word or Google Docs, follow the steps below.

Microsoft Word:

• Highlight the whole list and right click to open the Paragraph options.
• Under Indentation > Special , choose Hanging from the dropdown menu.
• Set the indent to 0.5 inches or 1.27cm.

Google Docs:

• Highlight the whole list and click on Format >  Align and indent >  Indentation options .
• Under  Special indent , choose Hanging from the dropdown menu.

When the hanging indent is applied, for each reference, every line except the first is indented. This helps the reader see where one entry ends and the next begins.

For a published interview (whether in video , audio, or print form ), you should always include a citation , just as you would for any other source.

For an interview you conducted yourself , formally or informally, you often don’t need a citation and can just refer to it in the text or in a footnote , since the reader won’t be able to look them up anyway. MLA , however, still recommends including citations for your own interviews.

The main elements included in a newspaper interview citation across APA , MLA , and Chicago style are the names of the interviewer and interviewee, the interview title, the publication date, the name of the newspaper, and a URL (for online sources).

The information is presented differently in different citation styles. One key difference is that APA advises listing the interviewer in the author position, while MLA and Chicago advise listing the interviewee first.

The elements included in a newspaper article citation across APA , MLA , and Chicago style are the author name, the article title, the publication date, the newspaper name, and the URL if the article was accessed online .

In APA and MLA, the page numbers of the article appear in place of the URL if the article was accessed in print. No page numbers are used in Chicago newspaper citations.

Untitled sources (e.g. some images ) are usually cited using a short descriptive text in place of the title. In APA Style , this description appears in brackets: [Chair of stained oak]. In MLA and Chicago styles, no brackets are used: Chair of stained oak.

For social media posts, which are usually untitled, quote the initial words of the post in place of the title: the first 160 characters in Chicago , or the first 20 words in APA . E.g. Biden, J. [@JoeBiden]. “The American Rescue Plan means a $7,000 check for a single mom of four. It means more support to safely.”

MLA recommends quoting the full post for something short like a tweet, and just describing the post if it’s longer.

The main elements included in image citations across APA , MLA , and Chicago style are the name of the image’s creator, the image title, the year (or more precise date) of publication, and details of the container in which the image was found (e.g. a museum, book , website ).

In APA and Chicago style, it’s standard to also include a description of the image’s format (e.g. “Photograph” or “Oil on canvas”). This sort of information may be included in MLA too, but is not mandatory.

The main elements included in a lecture citation across APA , MLA , and Chicago style are the name of the speaker, the lecture title, the date it took place, the course or event it was part of, and the institution it took place at.

For transcripts or recordings of lectures/speeches, other details like the URL, the name of the book or website , and the length of the recording may be included instead of information about the event and institution.

The main elements included in a YouTube video citation across APA , MLA , and Chicago style are the name of the author/uploader, the title of the video, the publication date, and the URL.

The format in which this information appears is different for each style.

All styles also recommend using timestamps as a locator in the in-text citation or Chicago footnote .

Each annotation in an annotated bibliography is usually between 50 and 200 words long. Longer annotations may be divided into paragraphs .

The content of the annotation varies according to your assignment. An annotation can be descriptive, meaning it just describes the source objectively; evaluative, meaning it assesses its usefulness; or reflective, meaning it explains how the source will be used in your own research .

Any credible sources on your topic can be included in an annotated bibliography . The exact sources you cover will vary depending on the assignment, but you should usually focus on collecting journal articles and scholarly books . When in doubt, utilize the CRAAP test !

An annotated bibliography is an assignment where you collect sources on a specific topic and write an annotation for each source. An annotation is a short text that describes and sometimes evaluates the source.

The elements included in journal article citations across APA , MLA , and Chicago style are the name(s) of the author(s), the title of the article, the year of publication, the name of the journal, the volume and issue numbers, the page range of the article, and, when accessed online, the DOI or URL.

In MLA and Chicago style, you also include the specific month or season of publication alongside the year, when this information is available.

In APA , MLA , and Chicago style citations for sources that don’t list a specific author (e.g. many websites ), you can usually list the organization responsible for the source as the author.

If the organization is the same as the website or publisher, you shouldn’t repeat it twice in your reference:

• In APA and Chicago, omit the website or publisher name later in the reference.
• In MLA, omit the author element at the start of the reference, and cite the source title instead.

If there’s no appropriate organization to list as author, you will usually have to begin the citation and reference entry with the title of the source instead.

The main elements included in website citations across APA , MLA , and Chicago style are the author, the date of publication, the page title, the website name, and the URL. The information is presented differently in each style.

When you want to cite a specific passage in a source without page numbers (e.g. an e-book or website ), all the main citation styles recommend using an alternate locator in your in-text citation . You might use a heading or chapter number, e.g. (Smith, 2016, ch. 1)

In APA Style , you can count the paragraph numbers in a text to identify a location by paragraph number. MLA and Chicago recommend that you only use paragraph numbers if they’re explicitly marked in the text.

For audiovisual sources (e.g. videos ), all styles recommend using a timestamp to show a specific point in the video when relevant.

The abbreviation “ et al. ” (Latin for “and others”) is used to shorten citations of sources with multiple authors.

“Et al.” is used in APA in-text citations of sources with 3+ authors, e.g. (Smith et al., 2019). It is not used in APA reference entries .

Use “et al.” for 3+ authors in MLA in-text citations and Works Cited entries.

Use “et al.” for 4+ authors in a Chicago in-text citation , and for 10+ authors in a Chicago bibliography entry.

Check if your university or course guidelines specify which citation style to use. If the choice is left up to you, consider which style is most commonly used in your field.

• APA Style is the most popular citation style, widely used in the social and behavioral sciences.
• MLA style is the second most popular, used mainly in the humanities.
• Chicago notes and bibliography style is also popular in the humanities, especially history.
• Chicago author-date style tends to be used in the sciences.

Other more specialized styles exist for certain fields, such as Bluebook and OSCOLA for law.

The most important thing is to choose one style and use it consistently throughout your text.

The main elements included in all book citations across APA , MLA , and Chicago style are the author, the title, the year of publication, and the name of the publisher. A page number is also included in in-text citations to highlight the specific passage cited.

In Chicago style and in the 6th edition of APA Style , the location of the publisher is also included, e.g. London: Penguin.

A block quote is a long quote formatted as a separate “block” of text. Instead of using quotation marks , you place the quote on a new line, and indent the entire quote to mark it apart from your own words.

The rules for when to apply block quote formatting depend on the citation style:

• APA block quotes are 40 words or longer.
• MLA block quotes are more than 4 lines of prose or 3 lines of poetry.
• Chicago block quotes are longer than 100 words.

In academic writing , there are three main situations where quoting is the best choice:

• To analyze the author’s language (e.g., in a literary analysis essay )
• To give evidence from primary sources
• To accurately present a precise definition or argument

Don’t overuse quotes; your own voice should be dominant. If you just want to provide information from a source, it’s usually better to paraphrase or summarize .

Every time you quote a source , you must include a correctly formatted in-text citation . This looks slightly different depending on the citation style .

For example, a direct quote in APA is cited like this: “This is a quote” (Streefkerk, 2020, p. 5).

Every in-text citation should also correspond to a full reference at the end of your paper.

A quote is an exact copy of someone else’s words, usually enclosed in quotation marks and credited to the original author or speaker.

The DOI is usually clearly visible when you open a journal article on an academic database. It is often listed near the publication date, and includes “doi.org” or “DOI:”. If the database has a “cite this article” button, this should also produce a citation with the DOI included.

If you can’t find the DOI, you can search on Crossref using information like the author, the article title, and the journal name.

A DOI is a unique identifier for a digital document. DOIs are important in academic citation because they are more permanent than URLs, ensuring that your reader can reliably locate the source.

Journal articles and ebooks can often be found on multiple different websites and databases. The URL of the page where an article is hosted can be changed or removed over time, but a DOI is linked to the specific document and never changes.

When a book’s chapters are written by different authors, you should cite the specific chapter you are referring to.

When all the chapters are written by the same author (or group of authors), you should usually cite the entire book, but some styles include exceptions to this.

• In APA Style , single-author books should always be cited as a whole, even if you only quote or paraphrase from one chapter.
• In MLA Style , if a single-author book is a collection of stand-alone works (e.g. short stories ), you should cite the individual work.
• In Chicago Style , you may choose to cite a single chapter of a single-author book if you feel it is more appropriate than citing the whole book.

Articles in newspapers and magazines can be primary or secondary depending on the focus of your research.

In historical studies, old articles are used as primary sources that give direct evidence about the time period. In social and communication studies, articles are used as primary sources to analyze language and social relations (for example, by conducting content analysis or discourse analysis ).

If you are not analyzing the article itself, but only using it for background information or facts about your topic, then the article is a secondary source.

A fictional movie is usually a primary source. A documentary can be either primary or secondary depending on the context.

If you are directly analyzing some aspect of the movie itself – for example, the cinematography, narrative techniques, or social context – the movie is a primary source.

If you use the movie for background information or analysis about your topic – for example, to learn about a historical event or a scientific discovery – the movie is a secondary source.

Whether it’s primary or secondary, always properly cite the movie in the citation style you are using. Learn how to create an MLA movie citation or an APA movie citation .

To determine if a source is primary or secondary, ask yourself:

• Was the source created by someone directly involved in the events you’re studying (primary), or by another researcher (secondary)?
• Does the source provide original information (primary), or does it summarize information from other sources (secondary)?
• Are you directly analyzing the source itself (primary), or only using it for background information (secondary)?

Some types of source are nearly always primary: works of art and literature, raw statistical data, official documents and records, and personal communications (e.g. letters, interviews ). If you use one of these in your research, it is probably a primary source.

Primary sources are often considered the most credible in terms of providing evidence for your argument, as they give you direct evidence of what you are researching. However, it’s up to you to ensure the information they provide is reliable and accurate.

Always make sure to properly cite your sources to avoid plagiarism .

Common examples of primary sources include interview transcripts , photographs, novels, paintings, films, historical documents, and official statistics.

Anything you directly analyze or use as first-hand evidence can be a primary source, including qualitative or quantitative data that you collected yourself.

Secondary Sources in Research

Other Academics' Observations on Primary Sources

In contrast to primary sources in  research  activities, secondary sources consist of information that has been gathered and often interpreted by other researchers and recorded in books, articles, and other publications. 

In her "Handbook of Research Methods , "  Natalie L. Sproull points out that secondary sources "are not necessarily worse than primary sources and can be quite valuable. A secondary source may include more information about more aspects of the event than did a primary source ."

Most often though, secondary sources act as a way to keep up with or discuss progress in a field of study, wherein a writer may use another's observations on a topic to summarize his or her own viewpoints on the matter to progress the discourse further.

The Difference Between Primary and Secondary Data

In the hierarchy of the relevance of the evidence to an argument, primary sources like original documents and first-hand accounts of events provide the strongest support to any given claim. By contrast, secondary sources provide a type of back-up to their primary counterparts.

To help explain this difference, Ruth Finnegan distinguishes primary sources as forming the "basic and original material for providing the researcher's raw evidence" in her 2006 article "Using Documents." Secondary sources, while still highly useful, are written by someone else after an event or about a document and can therefore only serve the purpose of furthering an argument if the source has credibility in the field.

Some, therefore, argue that secondary data is neither better nor worse than primary sources—it's simply different. Scot Ober discusses this concept in "Fundamentals of Contemporary Business Communication," saying "the source of the data is not as important as its quality and its relevance for your particular purpose."

Advantages and Disadvantages of Secondary Data

Secondary sources also provide advantages unique from primary sources, but Ober posits that the major ones are economic saying that "using secondary data is less costly and time-consuming than collecting primary data."

Still, secondary sources can also provide hindsight to historical events, providing the context and missing pieces of narratives by relating each event to others happening nearby at the same time. In terms of evaluations of documents and texts, secondary sources offer unique perspectives like historians have on the impact of bills such as the Magna Carta and the Bill of Rights in the U.S. Constitution.

However, Ober warns researchers that secondary sources also come with their fair share of disadvantages including quality and scarcity of sufficient secondary data, going so far as to say "never use any data before you have evaluated its appropriateness for the intended purpose."

A researcher must, therefore, vet the qualifications of the secondary source as it relates to the topic—for instance, a plumber writing an article about grammar may not be the most credible resource, whereas an English teacher would be more qualified to comment on the subject.

What Are Primary and Secondary Sources?

A primary source is a source that you are analyzing as the writer. In other words, there is no mediary between you and the text; you are the one doing the analysis.

Some examples of primary sources:

A secondary source , then, is a source that has also done analysis of the same (or a similar) topic. You will then use this source to discuss how it relates to your argument about the primary source. A secondary source is a mediary between you and the primary source. Secondary sources can also help your credibility as a writer; when you use them in your writing, it shows that you have done research on the topic, and can enter into the conversation on the topic with other writers.

Some examples of secondary sources:

Summary: When and How Do I Use It?

  One of the important distinctions to make when coming to terms with a text is knowing when to summarize it, when to paraphrase it, and when to quote it. Here’s what Joseph Harris, author of the textbook Rewriting: How to Do Things with Texts ,  has to say:

  “Summarize when what you have to say about a text is routine and quote when it is more contentious” (21).

In other words, quote when you need to rely on the voice of the writer, when you need the language of the text to help you make a point. Otherwise, try to use paraphrase or summary, so that your ideas are still the main focus.

 Summarizing a text can distract your reader from your argument, especially if you rely on lengthy summaries to capture a source in a nutshell. However, it can also prove an effective rhetorical tool: you just need to know when to use it.

You can use summary in the following ways:  

         - When the source offers important background about your ideas

       - When you need to provide your readers with an overview of a source’s entire argument before analyzing certain ideas from it

       - When the source either supports your thesis, or when it offers a position you want to argue against or analyze more in-depth

Here is a sample summary. What do you notice about it?

Ryuko Kubota argues in “Ideologies of English in Japan” that the debate over English’s place in the Japanese language disappeared with the militaristic rule of the 1930s and 1940s, when Japan rejected and/or suppressed the learning of English and other languages in favor of heavy nationalism. However, he adds that the debate returned during America’s occupation of Japan and has periodically been a topic for debate since.  Japanese politicians have always seen English as an important tool for Japan’s success as an industrial nation on a global scale. However, instead of molding itself to the English of the Western world, Japan has integrated English to fit its ideologies, to serve its own needs; indeed, to become part of the Japanese language.

1. This is a succinct summary; the entire summary is only three sentences.

2. The final sentence of the paragraph is the writer's attempt to make a connection between the article and her own ideas for her paper. This is an important step in using summary; it's important to always show the reader how/why the summary is important/relevant.

Paraphrasing: When/How/Why Should I Do It?

Paraphrasing gives you the room to condense a text’s ideas into your own words.  You can use this, for example, to rewrite a definition, to emphasize important points, or to clarify ideas that might be hard for the reader to understand if you quote the original text.

When you paraphrase, remember that you still need to cite the source in-text!

Depending on your field and the style guide your field follows, you may be required to paraphrase more than quote or summarize. Make sure you are familiar with the writing conventions for your field. APA, for example, draws much more on paraphrase than MLA.

Example of a Paraphrase

Let’s look at an example of a paraphrase.  Note that here the author of this paraphrase has used the author’s name first as an attributive tag – she is letting the reader know who wrote this.  She then goes on to put the writer’s ideas into her own words, but acknowledges directly where the ideas came from by using the in-text citation at the end of the second sentence.

    - This is a paraphrase for MLA; in APA, the year would come after Honna's name in parentheses.

In source-based or synthesis writing, we try to not only express our ideas using our own voice, but to also express our ideas through the voices of those we are citing. In their book Wriiting Analytically , Rosenwasser and Stephen offer six strategies to use in researched writing to make our sources speak, to make them come alive.

Here are some typical problems we encounter when using primary and secondary sources:

     - Leaving quotations and paraphrases to speak for themselves

     - Not differentiating your own voice from the voices of your sources (ventriloquizing)

     - Resorting to overly agreeing and disagreeing as your only means of responding to a source (other than summary)

Primary and secondary sources are nothing to fear. Many times we either leave sources to speak for themselves or ignore them altogether because we are afraid of losing our own voices. These strategies, listed below, are designed to help us know when and how to use quotes, and how not to become lost in the process.

Strategy 1: Make Your Sources Speak

v Quote, paraphrase, or summarize in order to analyze , as opposed to in place of analyzing.  Don’t assume that the meaning of your source material is self-evident.  Instead, explain to your readers what the quote, paraphrase, or summary means.  For example, what aspects do you find interesting or strange?  And relate these aspects to your overall thesis.   Your focus here in analysis should be on how the source leads you to your conclusion – beware of generalizing or putting two quotes next to each other without explaining the connection.

Using Strategy #1 : How are you using your sources?  Are you taking the time to develop points from your sources, or are you just using evidence – and is it clear why you are using it?  Highlight/bracket analysis, mark in a different color where analysis is not present immediately following source.  

Strategy 2: Use Your Sources to Ask Questions, Not Just to Provide Answers

v Use your selections from your sources as a means to raise issues and questions; avoid the temptation to use selections that provide answers without any commentary or further elaboration.  If you feel stuck with this, consider the source alongside other contexts (other sources, for example) and compare and contrast them to see if there are aspects of your topic that your source does not adequately address.

Using Strategy #2: Again, ask: how are you using your sources as question generators?  What how/why questions do your sources generate?  Look over the evidence you’ve used, and jot down the how/why questions you think your evidence creates.  Next, go through your paper.  Do you see yourself addressing these questions?  Mark your analysis appropriately so you can see how you’re addressing these questions (or not).  

Strategy 3: Put Your Sources in Conversation with One Another

v This is an extension of strategy 2.  Rather than limiting yourself to the only conversationalist with each source, aim for conversation among them.  Although it is not wrong to agree or disagree with your sources, it is wrong to see these as your only possible moves.  You should also understand that although it is sometimes useful and perhaps even necessary to agree or disagree, these judgments should 1) always be qualified and 2) occur only in certain contexts .  Instead of looking just at how you agree or disagree, try to imagine what these critics might say to one another.  Looking at sources in this way may prove useful as you explore your topics further in depth.

Using Strategy #3:

    This is a way for your sources to address one another directly, while also giving you more room to expand on your ideas through a slightly different form of analysis.  For example: what might the person you interviewed think about the secondary sources you found?  Would they agree with the claims you see your sources making, or would they disagree?  Why – what about their interview suggests this?  Make a list of possible dialogues your sources could have with one another.  

Strategy 4: Find Your Own Role in the Conversation

v Even though it’s important to not be the only person in the essay agreeing and disagreeing with the texts, it is important that you establish what you think and feel about each source.  After all, something compelled you to choose it, right?  In general, you have two options when you are in agreement with a source.  You can apply it in another context to qualify or expand its implications, or you can seek out other perspectives in order to break the hold it has on you.  In the first option, to do this, instead of focusing on the most important point, choose a lesser yet equally interesting point and work on developing that idea to see if it holds relevance to your topic.  The second option can also hold new perspectives if you allow yourself to be open to the possibilities of other perspectives that may or may not agree with your original source.

Using Strategy #4: While it’s important that you create a distinct voice for all the different kinds of sources you’ve used (interview, fieldwork, scholarly journals/books, etc.), it’s perhaps even more important that you have a clear role in this conversation that is your research essay.  Look over your paper: is it clear what you think?  Is it clear what is your voice, and what are the ideas/opinions of your sources? (Hint: your voice should still be clear in the midst of your sources, if you are taking the time to analyze them and develop your analysis as fully as possible.)  Highlight places where you voice – what you think – is clear.  Highlight in a different color places where your voice is unclear, or needs to be expressed more fully.

Strategy 5: Supply Ongoing Analysis of Sources (Don’t Wait Until the End)

v Instead of summarizing everything first and then leaving your analysis until the end, analyze as you quote or paraphrase a source .  This will help yield good conversation, by integrating your analysis of your sources into your presentation of them.

Using Strateg y #5:

Are your sources presented throughout the paper with careful analysis attending to each one?  Or are you presenting all your sources first, and analyzing them later?  Look through your paper, and mark places where you see yourself not analyzing your sources as you go.  Also: are there places where you see too much analysis, and not enough evidence?  Be sure to mark those places as well.  

Strategy 6: Attend Carefully to the Language of Your Sources by Quoting or Paraphrasing Them

v Rather than generalizing broadly about the ideas in your sources, you should spell out what you think is significant about their key words.  Quote sources if the actual language they use is important to your point; this practice will help you to present the view of your source fairly and accurately.  Your analysis will also benefit from the way the source represents its position (which may or may not be your position) with carefully chosen words and phrases.  Take advantage of this, and use the exact language to discuss the relevance (or not) of the quote to the issue you’re using it for.

Using Strategy #6: When paraphrasing or quoting a source, it’s important that you use the language of the source to help explain it – it keeps the reader in the moment with you, and helps him/her understand the key terms of that source – why you chose, why these words are so important, etc.  Look over your evidence, both quoted and paraphrased: are you using the language of the quote to help explain it?  Or is your analysis removed from the “moment of the source” (i.e. the language which the source uses to illustrate its point)?  Mark places where you think it’s important to use the language of the source to help analyze and develop the evidence more completely.

Strategies for Using Quotations In-Text

Acknowledge sources in your text, not just in citations:  

      “According to Lewis” or “Whitney argues.”

Use a set-up phrase, and splice the most important part of quotations in with your own words:

     According to Paul McCartney, “All you need is love.”

  Or phrase it with a set-up:

     Patrick Henry’s famous phrase is one of the first American schoolchildren memorize:

     “Give me liberty, or give me death.”

Anytime you use a quote, cite your source after the quotation:  

     Maxine Greene might attribute this resistance to “vaguely perceived expectations; they

     allow themselves to be programmed by organizations and official schedules or forms” (43).

Use ellipses to shorten quotations:

      “The album ‘OK Computer’ …pictured the onslaught of the information age and a young

        person’s panicky embrace of it” (Ross 85) .

Use square brackets to alter or add information within a quotation:  

      Popular music has always “[challenged] the mores of the older generation,” according to

      Nick Hornby.

Acc ording to Janet Gardner in her book Writing About Literature , there are three ways that we tend to use quotes:

Gardner advocates that we stay away from “floating quotations,” use at least an “attributed quotation,” and use “integrated quotations” as much as possible.

You will recognize a floating quotation when it looks as though the writer has simply lifted the passage from the original text, put quotations around it, and (maybe) identified the source.

Doing this can create confusion for the reader, who is left to guess the context and the reason for the quote.

This type of quoting reads awkward and choppy because there is no transition between your words and the language of the text you are quoting.

Example of a Floating Quotation; text taken from All She was Worth , by Miyuki Miyabe    

  Both Honma and Kyoko were rejected and looked down upon by Jun and Chizuko’s family when entering into marriage with their respective partners. “About her cousin – Jun’s father – and his family: what snobs they were, with fixed ideas on education and jobs” ( Miyabe 17).This passage shows that Honma and Kyoko were both being judged by their future in-laws by superficial stipulations.

What Is a Secondary Source

A secondary source is a type of source that acts as the instrument of the researcher’s understanding of the data set provided by the primary source. Not only that but the secondary source is also used to help code and explain the data obtained through the primary source.

How To Research and Obtain Secondary Sources

Secondary sources are readily available and can be sourced through various methods and actions. If you want to have a reference of how a secondary source looks you may read the articles named Working Primary and Secondary Sources , Practice Identifying Primary and Secondary Sources , and Teaching Primary and Secondary Sources on the links above, which will help with your overall understanding of both a primary and a secondary source .

Step 1: Select A Subject or Scientific Niche You Are Investigating

If you have not selected a subject or research question that you are tackling for your research paper, then you must first choose, create, or select the research topic you are going to write about. Be sure to write about something that you are wholly interested in as the writing process for the research topic is very arduous and time-consuming.

Step 2: Search Through an Online Catalog

One of the easiest ways to research and obtain secondary sources is via the act of searching and sifting through an online database or catalog. An example of an online catalog you can use is Google Scholar, which allows you to quickly search research topics to obtain any adjacent related literature.

Step 3: Use References Stated in the Reference or Bibliography of Other Research Articles

Another way you can obtain more references is through the utilization of the reference or bibliography section of any research paper you are citing and referencing. This will allow you to also glean information and data past researchers obtain throughout their research.

Step 4: Consult Experts Related to The Chosen Subject

You may also consult experts who are well-versed in the specific subject or niche you are choosing to tackle for your research paper. Not only will they be able to give you reliable data, but the experts can also be used to help out in the coding of the data obtained from the primary source.

What is the difference between a primary and a secondary source?

A primary source is a type of data source used in a research paper or scientific report that comes from first-hand experience and reliable gathered statistical data. Examples of this type of data source include survey questions or surveys , interview transcripts, and case studies. A secondary source, on the other hand, is a data source that the researcher uses to explain and interpret the dataset provided by the primary source. These types of sources come in the form of related literature, books, and other scholarly works used in the research process. Therefore the relationship between a primary and a secondary source is a very important concept to learn.

How do you identify secondary sources?

People can easily differentiate and identify primary and secondary sources from each other. This is mainly because the dataset the primary source provides originates from the research they are writing, whilst the secondary source comes from a source outside of the research article or paper. Not only that but the dataset from the secondary source also comes from the literature that the author will cite in the body of the research paper or article.

Why are secondary sources important?

Secondary sources allow the author, scholar, and writer to synthesize and extrapolate the information obtained and gathered from the primary source. This means that the secondary source is the instrument the researcher will use to code and analyze all the datasets and statistics from the primary source .

A secondary source is a type of reference and data source that the researchers use to explain and extrapolate the data obtained from the primary source. These often manifest themselves in the research paper as related literature, books, and other scholarly sources adjacent to the overall subject matter of the research. A well-researched scientific article will need the researcher, scholar, or author to obtain reliable and valid secondary sources to succinctly explain and support their data.
