It has been emphasised that good referencing is an important academic skill ( , 2015).
Information from (2015) emphasises that good referencing is an important academic skill.
You use secondary referencing when you want to refer to a source that is mentioned or quoted in the work you are reading. To do this, you add the phrase ‘quoted in’ or ‘cited in’ (depending on whether the author of the secondary source is directly quoting or summarising from the primary source) to your intext citation, along with the details of the source that you are reading.
West (2007, quoted in Birch, 2017, p. 17) state that… You would then include full references to Birch and The Open University in your reference list as these are the sources that you have read. There is no change to the structure of the full reference for these sources. |
You should include page numbers in your citation if you are quoting directly from or using ideas from a specific page or set of pages. Add the abbreviation p. (or pp. if more than one page) before the page number(s).
Harris (2015, p. 5) argues that… In the drying process "polyphenol oxidizing reactions" form new flavour compounds (Toker 2020, pp. 585–586)... |
Add a lower case letter to the date in the in-text citation and in the matching full reference to distinguish between the sources. : Snow is formed in part because the temperature drops enough that rain freezes (The Open University, 2022a), however the freezing temperature of water is often below 0°C under certain conditions (The Open University, 2022b).

Note: this only applies when you are using multiple different sources with the same author and year – if you are referring to the same source more than once then you do not need to add a letter to the date. The citation will be the same each time and you only need to include the source once in your reference list. |

If you're wondering how to write an academic essay with references, look no further. In this article, we'll discuss how to use in-text citations and references, including how to cite a website, how to cite a book, and how to cite a Tweet, according to various style guides.
You might need to cite sources when writing a paper that references other sources. For example, when writing an essay, you may use information from other works, such as books, articles, or websites. You must then inform readers where this information came from. Failure to do so, even accidentally, is plagiarism—passing off another person's work as your own.
You can avoid plagiarism and show readers where to find information by using citations and references.
Citations tell readers where a piece of information came from. They take the form of footnotes, endnotes, or parenthetical elements, depending on your style guide. In-text citations are usually placed at the end of a sentence containing the relevant information.
A reference list , bibliography, or works cited list at the end of a text provides additional details about these cited sources. This list includes enough publication information allowing readers to look up these sources themselves.
Referencing is important for more than simply avoiding plagiarism. Referring to a trustworthy source shows that the information is reliable. Referring to reliable information can also support your major points and back up your argument.
Learning how to write an academic essay with references and how to use in-text citations will allow you to cite authors who have made similar arguments. This helps show that your argument is objective and not entirely based on personal biases.
Often, a professor will assign a style guide. The purpose of a style guide is to provide writers with formatting instructions. If your professor has not assigned a style guide, they should still be able to recommend one.
If you are entirely free to choose, pick one that aligns with your field (for example, APA is frequently used for scientific writing).
Some of the most common style guides are as follows:
AP style for journalism
Chicago style for publishing
APA style for scholarly writing (commonly used in scientific fields)
MLA style for scholarly citations (commonly used in English literature fields)
Some journals have their own style guides, so if you plan to publish, check which guide your target journal uses. You can do this by locating your target journal's website and searching for author guidelines.
When learning how to write an academic essay with references, you must identify reliable sources that support your argument.
As you read, think critically and evaluate sources for:
Objectivity
Keep detailed notes on the sources so that you can easily find them again, if needed.
Tip: Record these notes in the format of your style guide—your reference list will then be ready to go.
An in-text citation in MLA includes the author's last name and the relevant page number:
(Author 123)
Here's how to cite a website in MLA:
Author's last name, First name. "Title of page."
Website. Website Publisher, date. Web. Date
retrieved. <URL>
With information from a real website, this looks like:
Morris, Nancy. "How to Cite a Tweet in APA,
Chicago, and MLA." Scribendi. Scribendi
Inc., n.d. Web. 22 Dec. 2021.
<https://www.scribendi.com/academy/articles/how_to_cite_a_website.en.html>
MLA uses the full text of a short Tweet (under 140 characters) as its title. Longer Tweets can be shortened using ellipses.
MLA Tweet references should be formatted as follows:
@twitterhandle (Author Name). "Text of Tweet." Twitter, Date Month, Year, time of
publication, URL.
With information from an actual Tweet, this looks like:
@neiltyson (Neil deGrasse Tyson). "You can't use reason to convince anyone out of an
argument that they didn't use reason to get into." Twitter, 29 Sept. 2020, 10:15 p.m.,
https://twitter.com/neiltyson/status/1311127369785192449 .
Here's how to cite a book in MLA:
Author's last name, First name. Book Title. Publisher, Year.
With publication information from a real book, this looks like:
Montgomery, L.M. Rainbow Valley. Frederick A. Stokes Company, 1919.
Author's last name, First name. "Title of Chapter." Book Title , edited by Editor Name,
Publisher, Year, pp. page range.
With publication information from an actual book, this looks like:
Ezell, Margaret J.M. "The Social Author: Manuscript Culture, Writers, and Readers." The
Broadview Reader in Book History , edited by Michelle Levy and Tom Mole, Broadview
Press, 2015,pp. 375–394.
You can cite a paraphrase in MLA exactly the same way as you would cite a direct quotation.
Make sure to include the author's name (either in the text or in the parenthetical citation) and the relevant page number.
In APA, in-text citations include the author's last name and the year of publication; a page number is included only if a direct quotation is used:
(Author, 2021, p. 123)
Here's how to cite a website in APA:
Author, A. A., & Author, B. B. (Year, Month. date of publication). Title of page. https://URL
Morris, N. (n.d.). How to cite a Tweet in APA, Chicago, and MLA.
https://www.scribendi.com/academy/articles/how_to_cite_a_website.en.html
Tip: Learn more about how to write an academic essay with references to websites .
APA refers to Tweets using their first 20 words.
Tweet references should be formatted as follows:
Author, A. A. [@twitterhandle). (Year, Month. date of publication). First 20 words of the
Tweet. [Tweet] Twitter. URL
When we input information from a real Tweet, this looks like:
deGrasse Tyson, N. [@neiltyson]. (2020, Sept. 29). You can't use reason to convince anyone
out of an argument that they didn't use reason to get into. [Tweet] Twitter.
https://twitter.com/neiltyson/status/1311127369785192449
Here's how to cite a book in APA:
Author, A. A. (Year). Book title. Publisher.
For a real book, this looks like:
Montgomery, L. M. (1919). Rainbow valley.
Frederick A. Stokes Company.
Author, A. A. (Year). Chapter title. In Editor Name (Ed.), Book Title (pp. page range).
With information from a real book, this looks like:
Ezell, M. J. M. (2014). The social author: Manuscript culture, writers, and readers. In
Michelle Levy and Tom Mole (Eds.), The Broadview Reader in Book History (pp. 375–
394). Broadview Press.
Knowing how to cite a book and how to cite a chapter in a book correctly will take you a long way in creating an effective reference list.
You can cite a paraphrase in APA the same way as you would cite a direct quotation, including the author's name and year of publication.
In APA, you may also choose to pinpoint the page from which the information is taken.
Referencing is an essential part of academic integrity. Learning how to write an academic essay with references and how to use in-text citations shows readers that you did your research and helps them locate your sources.
Learning how to cite a website, how to cite a book, and how to cite a paraphrase can also help you avoid plagiarism —an academic offense with serious consequences for your education or professional reputation.

Citation examples and full guides, frequently asked questions about citing sources.
Citations are required in all types of academic texts. They are needed for several reasons:
A citation is needed whenever you integrate a source into your writing. This usually means quoting or paraphrasing:
Citations are needed whether you quote or paraphrase, and whatever type of source you use. As well as citing scholarly sources like books and journal articles, don’t forget to include citations for any other sources you use for ideas, examples, or evidence. That includes websites, YouTube videos , and lectures .
Discover proofreading & editing
Usually, your institution (or the journal you’re submitting to) will require you to follow a specific citation style, so check your guidelines or ask your instructor.
In some cases, you may have to choose a citation style for yourself. Make sure to pick one style and use it consistently:
If in doubt, check with your instructor or read other papers from your field of study to see what style they follow.
In most styles, your citations consist of:
In-text citations most commonly take the form of parenthetical citations featuring the last name of the source’s author and its year of publication (aka author-date citations).
An alternative to this type of in-text citation is the system used in numerical citation styles , where a number is inserted into the text, corresponding to an entry in a numbered reference list.
There are also note citation styles , where you place your citations in either footnotes or endnotes . Since they’re not embedded in the text itself, these citations can provide more detail and sometimes aren’t accompanied by a full reference list or bibliography.
(London: John Murray, 1859), 510. |
A reference list (aka “Bibliography” or “Works Cited,” depending on the style) is where you provide full information on each of the sources you’ve cited in the text. It appears at the end of your paper, usually with a hanging indent applied to each entry.
The information included in reference entries is broadly similar, whatever citation style you’re using. For each source, you’ll typically include the:
The exact information included varies depending on the source type and the citation style. The order in which the information appears, and how you format it (e.g., capitalization, use of italics) also varies.
Most commonly, the entries in your reference list are alphabetized by author name. This allows the reader to easily find the relevant entry based on the author name in your in-text citation.
In numerical citation styles, the entries in your reference list are numbered, usually based on the order in which you cite them. The reader finds the right entry based on the number that appears in the text.
Because each style has many small differences regarding things like italicization, capitalization , and punctuation , it can be difficult to get every detail right. Using a citation generator can save you a lot of time and effort.
Scribbr offers citation generators for both APA and MLA style. Both are quick, easy to use, and 100% free, with no ads and no registration required.
Just input a URL or DOI or add the source details manually, and the generator will automatically produce an in-text citation and reference entry in the correct format. You can save your reference list as you go and download it when you’re done, and even add annotations for an annotated bibliography .
Once you’ve prepared your citations, you might still be unsure if they’re correct and if you’ve used them appropriately in your text. This is where Scribbr’s other citation tools and services may come in handy:

At college level, you must properly cite your sources in all essays , research papers , and other academic texts (except exams and in-class exercises).
Add a citation whenever you quote , paraphrase , or summarize information or ideas from a source. You should also give full source details in a bibliography or reference list at the end of your text.
The exact format of your citations depends on which citation style you are instructed to use. The most common styles are APA , MLA , and Chicago .
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.
The Scribbr Citation Generator is developed using the open-source Citation Style Language (CSL) project and Frank Bennett’s citeproc-js . It’s the same technology used by dozens of other popular citation tools, including Mendeley and Zotero.
You can find all the citation styles and locales used in the Scribbr Citation Generator in our publicly accessible repository on Github .
APA format is widely used by professionals, researchers, and students in the social and behavioral sciences, including fields like education, psychology, and business.
Be sure to check the guidelines of your university or the journal you want to be published in to double-check which style you should be using.
MLA Style is the second most used citation style (after APA ). It is mainly used by students and researchers in humanities fields such as literature, languages, and philosophy.

Why and when to reference.
Referencing is an important part of academic work. It puts your work in context, demonstrates the breadth and depth of your research, and acknowledges other people’s work. You should reference whenever you use someone else’s idea.

These webpages explain what referencing is, why it is important and give an overview of the main elements of how to reference. Our Referencing made simple tutorial opens in a new window and covers how to identify your source and create a reference with interactive examples.
Referencing correctly:
Whenever you use an idea from someone else's work, for example from a journal article, textbook or website, you should cite the original author to make it clear where that idea came from. This is the case regardless of whether you have paraphrased, summarised or directly quoted their work. This is a key part of good practice in academic writing.

Referencing styles, citing your sources with in-text citations, creating your reference list or bibliography, harvard referencing examples, frequently asked questions about referencing.
Each referencing style has different rules for presenting source information. For in-text citations, some use footnotes or endnotes , while others include the author’s surname and date of publication in brackets in the text.
The reference list or bibliography is presented differently in each style, with different rules for things like capitalisation, italics, and quotation marks in references.
Your university will usually tell you which referencing style to use; they may even have their own unique style. Always follow your university’s guidelines, and ask your tutor if you are unsure. The most common styles are summarised below.
Harvard referencing, the most commonly used style at UK universities, uses author–date in-text citations corresponding to an alphabetical bibliography or reference list at the end.
In-text citation | Sources should always be cited properly (Pears and Shields, 2019). |
---|---|
Reference list | Pears, R. and Shields, G. (2019) . 11th edn. London: MacMillan. |

In-text citations should be used whenever you quote, paraphrase, or refer to information from a source (e.g. a book, article, image, website, or video).
Quoting is when you directly copy some text from a source and enclose it in quotation marks to indicate that it is not your own writing.
Paraphrasing is when you rephrase the original source into your own words. In this case, you don’t use quotation marks, but you still need to include a citation.
In most referencing styles, page numbers are included when you’re quoting or paraphrasing a particular passage. If you are referring to the text as a whole, no page number is needed.
In-text citations are quick references to your sources. In Harvard referencing, you use the author’s surname and the date of publication in brackets.
Up to three authors are included in a Harvard in-text citation. If the source has more than three authors, include the first author followed by ‘ et al. ‘
Number of authors | Harvard in-text citation example |
---|---|
1 author | (Jones, 2017) |
2 authors | (Jones and Singh, 2017) |
3 authors | (Jones, Singh and Smith, 2017) |
4+ authors | (Jones et al., 2017) |
The point of these citations is to direct your reader to the alphabetised reference list, where you give full information about each source. For example, to find the source cited above, the reader would look under ‘J’ in your reference list to find the title and publication details of the source.
In-text citations should be placed directly after the quotation or information they refer to, usually before a comma or full stop. If a sentence is supported by multiple sources, you can combine them in one set of brackets, separated by a semicolon.
If you mention the author’s name in the text already, you don’t include it in the citation, and you can place the citation immediately after the name.
The terms ‘bibliography’ and ‘reference list’ are sometimes used interchangeably. Both refer to a list that contains full information on all the sources cited in your text. Sometimes ‘bibliography’ is used to mean a more extensive list, also containing sources that you consulted but did not cite in the text.
A reference list or bibliography is usually mandatory, since in-text citations typically don’t provide full source information. For styles that already include full source information in footnotes (e.g. OSCOLA and Chicago Style ), the bibliography is optional, although your university may still require you to include one.
Reference lists are usually alphabetised by authors’ last names. Each entry in the list appears on a new line, and a hanging indent is applied if an entry extends onto multiple lines.
Different source information is included for different source types. Each style provides detailed guidelines for exactly what information should be included and how it should be presented.
Below are some examples of reference list entries for common source types in Harvard style.
Format | Author surname, initial. (Year) . City: Publisher. |
Example | Saunders, G. (2017) . New York: Random House. |
Format | Author surname, initial. (Year) ‘Chapter title’, in Editor name (ed(s).) . City: Publisher, page range. |
Example | Berman, R. A. (2004) ‘Modernism and the bildungsroman: Thomas Mann’s Magic Mountain’, in Bartram, G. (ed.) . Cambridge: Cambridge University Press, pp. 77–92. |
Format | Author surname, initial. (Year) ‘Article title’, , Volume(Issue), page range. |
Example | Adair, W. (1989) ‘ and : Hemingway’s debt to Thomas Mann’, , 35(4), pp. 429–444. |
Format | Author surname, initial. (Year) . Available at: URL (Accessed: Day Month Year). |

Your university should tell you which referencing style to follow. If you’re unsure, check with a supervisor. Commonly used styles include:
Your university may have its own referencing style guide.
If you are allowed to choose which style to follow, we recommend Harvard referencing, as it is a straightforward and widely used style.
References should be included in your text whenever you use words, ideas, or information from a source. A source can be anything from a book or journal article to a website or YouTube video.
If you don’t acknowledge your sources, you can get in trouble for plagiarism .
To avoid plagiarism , always include a reference when you use words, ideas or information from a source. This shows that you are not trying to pass the work of others off as your own.
You must also properly quote or paraphrase the source. If you’re not sure whether you’ve done this correctly, you can use the Scribbr Plagiarism Checker to find and correct any mistakes.
Harvard referencing uses an author–date system. Sources are cited by the author’s last name and the publication year in brackets. Each Harvard in-text citation corresponds to an entry in the alphabetised reference list at the end of the paper.
Vancouver referencing uses a numerical system. Sources are cited by a number in parentheses or superscript. Each number corresponds to a full reference at the end of the paper.
Harvard style | Vancouver style | |

9. Do one special edit especially for Referencing Style. The top students edit their essays three to five times spaced out over a week or more before submitting. One of those edits should be specifically for ensuring your reference list adheres to the referencing style that your teacher requires.
2. Provide the title of the book in italics. Type the title of the book in sentence case, capitalizing only the first word and any proper nouns in the title. If the book has a subtitle, add it in sentence case after the title. Use a colon to separate the title and the subtitle. Place a period at the end.
