• Citing Sources & Organizing Research

Primary sources provide first-hand testimony or direct evidence concerning a topic under investigation. They are created by witnesses or recorders who experienced the events or conditions being documented.

Often these sources are created at the time when the events or conditions are occurring, but primary sources can also include autobiographies, memoirs, and oral histories recorded later.

Primary sources are characterized by their content, regardless of the format available. (Handwritten notes could be published; the published book might be digitized or put on microfilm, but those notes are still primary sources in any format).

Some types of primary sources:

• Original documents (excerpts or translations acceptable): Diaries, speeches, manuscripts, letters, interviews, news film footage, contemporary newspaper articles, autobiographies, official records, pamphlets, meeting notes, photographs, contemporary sketches
• Creative works : Poetry, drama, novels, music, art 
• Relics or artifacts : Furniture, clothing, buildings

Examples of primary sources include:

• A poster from the Brotherhood of Sleeping Car Porters' 1962 strike
• The papers of William James
• A 1970 U.S. State Dept document updating Nixon on U.S.-Soviet space cooperation activities (Harvard login)
• A British pamphlet: "Electric Lighting for Country Houses," 1898
• Phineas Gage's skull
• The text of J. Robert Oppenheimer's "Atomic Weapons" presentation to the American Philosophical Society

Outline of Primary Sources for History

Archives and Manuscripts

Archives and manuscripts are the unpublished records of persons (letters, notes, diaries, etc.) and organizations. What are Archives?   Usually each archival collection has a (short) catalog record and a detailed finding aid (which is often available online).

• "Catalog record” refers to the kind of record found in library online catalogs, similar to those for books, although often a bit longer. Example of an Archive record .
• “Finding aid” (sometimes called an inventory) generally refers to a list of the folder labels for the collection, accompanied by a brief collection overview (scope and contents note) and a biographical (or institutional) note on the creator of the collection.  Finding aids may be as long as needed given the size of the collection.  They vary considerably according to the practices of individual repositories. Example of a Finding aid .

To find  Archives and manuscripts  at Harvard, go to  HOLLIS Advanced search .  Search your keywords or Subject terms (see the  HOLLIS page of this guide ) in the Library Catalog, limiting to Resource Type: Archives/Manuscripts.  You can choose the library at the right (Search Scope).  Countway  Medicine has abundant medical archives, and Schlesinger has many archives of women activists, many in health and reproductive rights fields.    Sample search on Subject: Women health .

How to find resources by format

Why use primary resources.

Primary sources provide first-hand testimony or direct evidence concerning a topic under investigation. They present original thinking, report a discovery, or share new information. Use primary sources in historical research, or researching precedent or context on a particular topic. 

Primary sources are created by witnesses or recorders who experienced the events or conditions being documented. They are from the time period involved and have not been filtered through subsequent interpretation or evaluation.

Determining what is a primary source can be tricky and depends on the topic, subject, and discipline you are researching. The types of information that can be considered primary sources may vary depending on the subject or discipline. Also how you are using the material in your paper or project can effect this determination. For some papers or projects it may be important to view the original object but for others a primary source that has been scanned and is online is acceptable.

The types of information that can be considered primary sources may vary depending on the subject or discipline, and also on how you are using the material. For example:

• A magazine article reporting on recent studies linking the reduction of energy consumption to the compact fluorescent light bulb would be a secondary source.
• A research article or study proving this would be a primary source.
• However, if you were studying how compact fluorescent light bulbs are presented in the popular media, the magazine article could be considered a primary source.

Tip:  If you are unsure if a source you have found is primary, talk to your instructor, librarian, or archivist.

Definitions

Primary sources  are original records created at the time historical events occurred or well after events in the form of memoirs and oral histories. Primary sources are distinguished from secondary sources, which are produced some time after an event, and serve to analyze or interpret primary sources.

Archives and Manuscripts  consist of original unpublished, historical and contemporary material. 

Primary sources in reproduction  For some levels of research it is acceptable and appropriate to use primary sources that have been reproduced and published. A few examples include microfilmed newspaper articles, published diaries, and scanned images of original documents published in book form. 

Search strategies

When beginning your research, searching for primary sources is similar to other kinds of research:

• Brainstorm the kinds of sources you might need. News sources? Journals from the time period? Government documents? Have a date range in mind to narrow your search.
• Diaries, letters, and other personal papers are often unique items held in archives or special collections. One trick is to google the name of the person you're researching and the word "papers." If they are being held at another institution, you might find out if they've been digitized or not. 
• Brainstorm and track your keywords and subject terms. Use a thesaurus to think of more keywords or older terms you may not be familiar with, but may have been commonly used during the time period you are researching. Are the records likely to be in another language or another alphabet? Do you have expertise in this language? Knowing ahead of time might help with your search.
• Think about where records might be held. Because of historical colonialism and imperialism, some communities may not have control over their own records and materials. They may be held in another country entirely. 
• Arrange a visit to our Archives and Special Collections if your topic is related to the University or Minnesota history. 
• Browse our collections of online primary source databases . 

Searching in the Libraries collections

The catalog provides many types of primary sources: original archival materials, print materials with the original texts, printed facsimiles, and online resources that link to digital facsimiles. You can recognize such an item if the word "sources" appears in the subject. That word and certain others, especially when searched as a subject keyword, will help narrow your search results to primary sources.

Archival materials on campus are searchable in more depth via this  their description of their collections .

When searching our collection, use the  Libraries' Advanced Search  and enter your keywords, plus the subject term source to your search. For example, this is an Advanced search with two subject contains filters set as "Holocaust’ and ‘sources." The date range is set to start "1937" and end "1950."

Start with a broad search; you can always narrow it further after you begin searching. 

For some topics, try a more specific subject keyword instead, for example:

• personal narratives
• autobiography

Depending on the focus of your research, there are other formats that may serve as primary source material. Here are some examples:

• advertisements
• archaeological artifacts
• birth certificates
• census material
• congressional/parliamentary hearings and reports
• correspondence
• county records
• documentary photographs
• government documents
• inscriptions
• manuscripts
• news sources
• oral histories
• organizational minutes
• records of organizations
• voting records

Subject Guides

Look for subject guides in the arts, humanities, social sciences and professional programs. Each list varies and may include recommended primary source databases or other resources in that field. Even though a list may not include a primary source section, the librarian for that subject area can suggest resources and/or strategies for your topic. Consult the complete list of  subject librarians  if you need assistance in other areas of research.

History, Humanities, Social Sciences

Primary sources in these disciplines are original records created at the time historical events occurred or well after events in the form of memoirs and oral histories.

Examples include:  Letters, manuscripts, diaries, rare books, historical photographs, first-hand accounts, or documentary sources on a subject, person, event or issue; newspapers written at the time of an event, song, or film from time period, historical maps, government reports or data, and more.

Primary Sources in Arts, Humanities, and Social Sciences

South Asia Primary Sources

Health Sciences, Sciences, Engineering

Primary sources in the sciences are original materials or information on which other research is based. Primary sources are also sets of data, such as health statistics, which have been tabulated, but not interpreted.

Examples include:  Journal articles of original research (written by person who did the research), patents, conference papers, dissertations, technical reports, or something personal like Einstein’s diary).

Primary sources are materials that were either created during the time period being studied or were created at a later date by a participant in the events being studied, such as, a childhood memoir. They are original documents [i.e., they are not about another document or account] and reflect the individual viewpoint of a participant or observer. Primary sources represent direct, uninterpreted records of the subject of your research study.

NOTE: Information about identifying and using primary resources materials, particularly those held in the USC Libraries, can be found in the Libraries Primary Sources Research Guide .

Value of Using Primary Sources

Primary sources enable you to get as close as possible to understanding the lived experiences of others and discovering what actually happened during an event. They can expose you to multiple perspectives concerning significant issues about the past and its relationship to the present. Integrating primary sources into your paper facilitates interpretations of events and issues that have not been filtered through the lens of others. In this way, primary sources represent the raw materials of doing research.

Keep in mind, however, that what constitutes a primary or secondary source depends on the context in which it is being used. For example, David McCullough’s biography of John Adams would be a secondary source for a paper about John Adams, but a primary source for a paper about how various historians have interpreted the presidency of John Adams. When in doubt about the source status of an item, ask a librarian for assistance!

Reviewing primary source material can be of value in improving your overall research paper because they :

• Are original materials,
• Were created from the time period involved,
• Have not been filtered through interpretation or evaluation by others, and
• Represent original thinking or experiences, reporting of a discovery, or the sharing of new information.

Examples of primary documents you could review as part of your overall study include :

• Artifacts [e.g. furniture or clothing, all from the time under study]
• Audio recordings [e.g. radio programs]
• Internet communications on email, listservs, blogs, Twitter, Facebook, and other social media platforms
• Interviews [e.g., oral histories, telephone, e-mail]
• Newspaper articles written at the time
• Original official documents [e.g., birth certificate, will, marriage license, trial transcript]
• Personal correspondence [e.g., letters]
• Photographs
• Proceedings of meetings, conferences and symposia
• Records of organizations, government agencies [e.g. annual report, treaty, constitution, government document]
• Survey Research [e.g., market surveys, public opinion polls]
• Transcripts of radio and television programs
• Video recordings
• Works of art, architecture, literature, and music [e.g., paintings, sculptures, musical scores, buildings, novels, poems]

NOTE: Primary source materials are often viewed as historical resources or objects that generally reside in archives or special collections and, thus, symbolize the past in some way. However, all of the examples of primary sources listed above are constantly being generated by governments, organizations, companies, individuals, and other entities and, therefore, can be used in papers that discuss or examine very recent and contemporary research problems [e.g., using a map to show the impact of an on-going natural disaster; a speech given yesterday by the U.S. Secretary of State]. Primary sources can represent and bring attention to anything in your paper regardless of when they were produced or made accessible.
