How to Quote | Citing Quotes in Harvard & APA

Published on 15 April 2022 by Shona McCombes and Jack Caulfield. Revised on 3 September 2022.

Quoting means copying a passage of someone else’s words and crediting the source. To quote a source, you must ensure:

• The quoted text is enclosed in quotation marks (usually single quotation marks in UK English, though double is acceptable as long as you’re consistent) or formatted as a block quote
• The original author is correctly cited
• The text is identical to the original

The exact format of a quote depends on its length and on which citation style you are using. Quoting and citing correctly is essential to avoid plagiarism , which is easy to detect with a good plagiarism checker .

Every time you quote, you must cite the source correctly . This looks slightly different depending on the citation style you’re using.

Citing a quote in Harvard style

When you include a quote in Harvard style, you must add a Harvard in-text citation giving the author’s last name, the year of publication, and a page number if available. Any full stop or comma appears after the citation, not within the quotation marks.

Citations can be parenthetical or narrative. In a parenthetical citation , you place all the information in brackets after the quote. In a narrative citation , you name the author in your sentence (followed by the year), and place the page number after the quote.

• Evolution is a gradual process that ‘can act only by very short and slow steps’ (Darwin, 1859, p. 510) . Darwin (1859) explains that evolution ‘can act only by very short and slow steps’ (p. 510) .

Citing a quote in APA Style

To cite a direct quote in APA , you must include the author’s last name, the year, and a page number, all separated by commas. If the quote appears on a single page, use ‘p.’; if it spans a page range, use ‘pp.’

An APA in-text citation can be parenthetical or narrative. In a parenthetical citation , you place all the information in parentheses after the quote. In a narrative citation , you name the author in your sentence (followed by the year), and place the page number after the quote.

Punctuation marks such as full stops and commas are placed after the citation, not within the quotation marks.

• Evolution is a gradual process that ‘can act only by very short and slow steps’ (Darwin, 1859, p. 510) .
• Darwin (1859) explains that evolution ‘can act only by very short and slow steps’ (p. 510) .

Make sure you integrate quotes properly into your text by introducing them in your own words, showing the reader why you’re including the quote and providing any context necessary to understand it.  Don’t  present quotations as stand-alone sentences.

There are three main strategies you can use to introduce quotes in a grammatically correct way:

• Add an introductory sentence
• Use an introductory signal phrase
• Integrate the quote into your own sentence

The following examples use APA Style citations, but these strategies can be used in all styles.

Introductory sentence

Introduce the quote with a full sentence ending in a colon . Don’t use a colon if the text before the quote isn’t a full sentence.

If you name the author in your sentence, you may use present-tense verbs, such as “states’, ‘argues’, ‘explains’, ‘writes’, or ‘reports’, to describe the content of the quote.

• In Denmark, a recent poll shows that: ‘A membership referendum held today would be backed by 55 percent of Danish voters’ (Levring, 2018, p. 3).
• In Denmark, a recent poll shows that support for the EU has grown since the Brexit vote: ‘A membership referendum held today would be backed by 55 percent of Danish voters’ (Levring, 2018, p. 3).
• Levring (2018) reports that support for the EU has grown since the Brexit vote: ‘A membership referendum held today would be backed by 55 percent of Danish voters’ (p. 3).

Introductory signal phrase

You can also use a signal phrase that mentions the author or source but doesn’t form a full sentence. In this case, you follow the phrase with a comma instead of a colon.

• According to a recent poll, ‘A membership referendum held today would be backed by 55 percent of Danish voters’ (Levring, 2018, p. 3).
• As Levring (2018) explains, ‘A membership referendum held today would be backed by 55 percent of Danish voters’ (p. 3).

Integrated into your own sentence

To quote a phrase that doesn’t form a full sentence, you can also integrate it as part of your sentence, without any extra punctuation.

• A recent poll suggests that EU membership ‘would be backed by 55 percent of Danish voters’ in a referendum (Levring, 2018, p. 3).
• Levring (2018) reports that EU membership ‘would be backed by 55 percent of Danish voters’ in a referendum (p. 3).

When you quote text that itself contains another quote, this is called a nested quotation or a quote within a quote. It may occur, for example, when quoting dialogue from a novel.

To distinguish this quote from the surrounding quote, you enclose it in double (instead of single) quotation marks (even if this involves changing the punctuation from the original text). Make sure to close both sets of quotation marks at the appropriate moments.

Note that if you only quote the nested quotation itself, and not the surrounding text, you can just use single quotation marks.

• Carraway introduces his narrative by quoting his father: ‘ ‘ Whenever you feel like criticizing anyone, ‘ he told me, ‘ just remember that all the people in this world haven’t had the advantages that you’ve had ‘ ‘ (Fitzgerald 1).
• Carraway introduces his narrative by quoting his father: ‘”Whenever you feel like criticizing anyone,” he told me, “just remember that all the people in this world haven’t had the advantages that you’ve had “  (Fitzgerald 1).
• Carraway introduces his narrative by quoting his father: ‘“Whenever you feel like criticizing anyone,” he told me, “just remember that all the people in this world haven’t had the advantages that you’ve had”’ (Fitzgerald 1).
• Carraway begins by quoting his father’s invocation to ‘remember that all the people in this world haven’t had the advantages that you’ve had’ (Fitzgerald 1).

Note:  When the quoted text in the source comes from another source, it’s best to just find that original source in order to quote it directly. If you can’t find the original source, you can instead cite it indirectly .

Often, incorporating a quote smoothly into your text requires you to make some changes to the original text. It’s fine to do this, as long as you clearly mark the changes you’ve made to the quote.

Shortening a quote

If some parts of a passage are redundant or irrelevant, you can shorten the quote by removing words, phrases, or sentences and replacing them with an ellipsis (…). Put a space before and after the ellipsis.

Be careful that removing the words doesn’t change the meaning. The ellipsis indicates that some text has been removed, but the shortened quote should still accurately represent the author’s point.

Altering a quote

You can add or replace words in a quote when necessary. This might be because the original text doesn’t fit grammatically with your sentence (e.g., it’s in a different tense), or because extra information is needed to clarify the quote’s meaning.

Use brackets to distinguish words that you have added from words that were present in the original text.

The Latin term ‘ sic ‘ is used to indicate a (factual or grammatical) mistake in a quotation. It shows the reader that the mistake is from the quoted material, not a typo of your own.

In some cases, it can be useful to italicise part of a quotation to add emphasis, showing the reader that this is the key part to pay attention to. Use the phrase ’emphasis added’ to show that the italics were not part of the original text.

You usually don’t need to use brackets to indicate minor changes to punctuation or capitalisation made to ensure the quote fits the style of your text.

If you quote more than a few lines from a source, you must format it as a block quote . Instead of using quotation marks, you set the quote on a new line and indent it so that it forms a separate block of text.

Block quotes are cited just like regular quotes, except that if the quote ends with a full stop, the citation appears after the full stop.

To the end of his days Bilbo could never remember how he found himself outside, without a hat, a walking-stick or any money, or anything that he usually took when he went out; leaving his second breakfast half-finished and quite unwashed-up, pushing his keys into Gandalf’s hands, and running as fast as his furry feet could carry him down the lane, past the great Mill, across The Water, and then on for a mile or more. (16)

Avoid relying too heavily on quotes in academic writing . To integrate a source , it’s often best to paraphrase , which means putting the passage into your own words. This helps you integrate information smoothly and keeps your own voice dominant.

However, there are some situations in which quotes are more appropriate.

When focusing on language

If you want to comment on how the author uses language (for example, in literary analysis ), it’s necessary to quote so that the reader can see the exact passage you are referring to.

When giving evidence

To convince the reader of your argument, interpretation or position on a topic, it’s often helpful to include quotes that support your point. Quotes from primary sources (for example, interview transcripts or historical documents) are especially credible as evidence.

When presenting an author’s position or definition

When you’re referring to secondary sources such as scholarly books and journal articles, try to put others’ ideas in your own words when possible.

But if a passage does a great job at expressing, explaining, or defining something, and it would be very difficult to paraphrase without changing the meaning or losing the weakening the idea’s impact, it’s worth quoting directly.

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

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

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.

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.

If you’re quoting from a text that paraphrases or summarises other sources and cites them in parentheses , APA  recommends retaining the citations as part of the quote:

• Smith states that ‘the literature on this topic (Jones, 2015; Sill, 2019; Paulson, 2020) shows no clear consensus’ (Smith, 2019, p. 4).

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

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.

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.

APA uses block quotes for quotes that are 40 words or longer.

We all love a good quote. They’re memorable (“I’ll be back” – The Terminator), they communicate a lot succinctly (“Genius is 1 percent inspiration, 99 percent perspiration” – Thomas Edison), and you can use them in papers to help support your thesis statement. After all, the best research papers include references from other sources.

It can be tempting to throw in as many catchy quotes as possible but believe us when we say it’s totally not worth it. This method is deeply flawed. It doesn’t tell the reader where you got the quote or information and therefore doesn’t add credibility to your paper—you could’ve just made the whole thing up! So when you include a quote in your paper, you must provide a citation to give this important context.

So how do you write citations that properly tie in with your quotes? Here, we cover the basics for the most popular citation styles.

Need help seeing if anything in your paper needs a citation (or basic edits)? Citation Machine Plus’s grammar and essay checker may be for you! It’ll help detect grammatical errors, scan for potential plagiarism, and create automatic citations.

MLA style, short for “Modern Language Association,” is often used in social science, English, literature, and writing courses. This style uses an “author locator” system of citing. What this means is that generally, for the citation following the quote, you need to include the name of the author and the page number of the source you are quoting.

Here is an example of how to cite a quote within the text in MLA style:

When Scout says, “Well if we came out durin’ the Old Testament it’s too long ago to matter,” she is referring to her confusion as to how society is so capable of dividing different people into different classes (Lee 47).

Note that the parenthetical citation , or “in-text” citation, comes before the ending punctuation mark of the sentence.

These in-text citations correspond to a full citation that is located at the end of the paper. In MLA style, this list of full citations is called a “Works Cited” page.

Here is what the matching full citation would be for this in-text citation:

Lee, Harper.  To Kill a Mockingbird.* Harper Collins, 1960.

*Titles for sources are set in title case for MLA style citations.

If you need help with in-text and parenthetical citations, CitationMachine.net, can help. Our MLA citation generator is simple and easy to use!

Citations in APA, short for “American Psychological Association,” are very similar to those of the MLA citation system. This style is used mostly in science and psychology courses.

Instead of the page number, however, the date of publication is included with the author’s last name in the in-text citation.

Here is an example of how to cite a quote within the text in APA style:

When Scout says, “Well if we came out durin’ the Old Testament it’s too long ago to matter,” she is referring to her confusion as to how society is so capable of dividing different people into different classes (Lee, 1960).

These in-text citations, like in MLA style, also correspond to a full citation that is located at the end of the paper. In APA style, this list of full citations is called a “References” page.

The corresponding entry on the references page looks a bit different than an entry on a “Works Cited” page. Here is what the matching full citation would be for this in-text citation in APA :

Lee, H. (1960).  To kill a mockingbird . Philadelphia: Harper Collins.

*Titles for sources are often set in sentence case for APA-style citations. Check for rules that pertain to your particular source before handing in your paper.

About This Article

To cite a quote using APA, put parentheses with the citation directly after the quoted material. For a citation with one or more authors, include their last names, the year of publication, and page number preceded by a "p.” If you're citing something but don't know the author, put the title of the publication and its date in parentheses. You can follow the same author-date format to cite web pages, but if you don't know the author or the date, use a shortened version of the web page title and write "n.d." after for "no date."

Quoting and integrating sources into your paper

In any study of a subject, people engage in a “conversation” of sorts, where they read or listen to others’ ideas, consider them with their own viewpoints, and then develop their own stance. It is important in this “conversation” to acknowledge when we use someone else’s words or ideas. If we didn’t come up with it ourselves, we need to tell our readers who did come up with it.

It is important to draw on the work of experts to formulate your own ideas. Quoting and paraphrasing the work of authors engaged in writing about your topic adds expert support to your argument and thesis statement. You are contributing to a scholarly conversation with scholars who are experts on your topic with your writing. This is the difference between a scholarly research paper and any other paper: you must include your own voice in your analysis and ideas alongside scholars or experts.

All your sources must relate to your thesis, or central argument, whether they are in agreement or not. It is a good idea to address all sides of the argument or thesis to make your stance stronger. There are two main ways to incorporate sources into your research paper.

Quoting is when you use the exact words from a source. You will need to put quotation marks around the words that are not your own and cite where they came from. For example:

“It wasn’t really a tune, but from the first note the beast’s eyes began to droop . . . Slowly the dog’s growls ceased – it tottered on its paws and fell to its knees, then it slumped to the ground, fast asleep” (Rowling 275).

Follow these guidelines when opting to cite a passage:

• Choose to quote passages that seem especially well phrased or are unique to the author or subject matter.
• Be selective in your quotations. Avoid over-quoting. You also don’t have to quote an entire passage. Use ellipses (. . .) to indicate omitted words. Check with your professor for their ideal length of quotations – some professors place word limits on how much of a sentence or paragraph you should quote.
• Before or after quoting a passage, include an explanation in which you interpret the significance of the quote for the reader. Avoid “hanging quotes” that have no context or introduction. It is better to err on the side of your reader not understanding your point until you spell it out for them, rather than assume readers will follow your thought process exactly.
• If you are having trouble paraphrasing (putting something into your own words), that may be a sign that you should quote it.
• Shorter quotes are generally incorporated into the flow of a sentence while longer quotes may be set off in “blocks.” Check your citation handbook for quoting guidelines.

Paraphrasing is when you state the ideas from another source in your own words . Even when you use your own words, if the ideas or facts came from another source, you need to cite where they came from. Quotation marks are not used. For example:

With the simple music of the flute, Harry lulled the dog to sleep (Rowling 275).

Follow these guidelines when opting to paraphrase a passage:

• Don’t take a passage and change a word here or there. You must write out the idea in your own words. Simply changing a few words from the original source or restating the information exactly using different words is considered plagiarism .
• Read the passage, reflect upon it, and restate it in a way that is meaningful to you within the context of your paper . You are using this to back up a point you are making, so your paraphrased content should be tailored to that point specifically.
• After reading the passage that you want to paraphrase, look away from it, and imagine explaining the main point to another person.
• After paraphrasing the passage, go back and compare it to the original. Are there any phrases that have come directly from the original source? If so, you should rephrase it or put the original in quotation marks. If you cannot state an idea in your own words, you should use the direct quotation.

A summary is similar to paraphrasing, but used in cases where you are trying to give an overview of many ideas. As in paraphrasing, quotation marks are not used, but a citation is still necessary. For example:

Through a combination of skill and their invisibility cloak, Harry, Ron, and Hermione slipped through Hogwarts to the dog’s room and down through the trapdoor within (Rowling 271-77).

Important guidelines

When integrating a source into your paper, remember to use these three important components:

• Introductory phrase to the source material : mention the author, date, or any other relevant information when introducing a quote or paraphrase.
• Source material : a direct quote, paraphrase, or summary with proper citation.
• Analysis of source material : your response, interpretations, or arguments regarding the source material should introduce or follow it. When incorporating source material into your paper, relate your source and analysis back to your original thesis.

Ideally, papers will contain a good balance of direct quotations, paraphrasing and your own thoughts. Too much reliance on quotations and paraphrasing can make it seem like you are only using the work of others and have no original thoughts on the topic.

Always properly cite an author’s original idea, whether you have directly quoted or paraphrased it. If you have questions about how to cite properly in your chosen citation style, browse these citation guides . You can also review our guide to understanding plagiarism .

University Writing Center

The University of Nevada, Reno Writing Center provides helpful guidance on quoting and paraphrasing and explains how to make sure your paraphrasing does not veer into plagiarism.

Work Quoted in Another Source

Sometimes an author of a book, article or website will mention another person’s work by using a quotation or paraphrased idea from that source. ( This may be called a secondary source.)  For example, the Kirkey article you are reading includes a quotation by Smith that you would like to include in your essay.

• If it is possible to retrieve the original source of the quotation (in this case, Smith), verify the quote and cite the original source.
• You will add the words “as cited in” to your in-text citation. Examples below.

Examples of in-text citations:

According to a study by Smith (as cited in Kirkey, 2013) 42% of doctors would refuse to perform legal euthanasia.

Smith (as cited in Kirkey, 2013) states that “even if euthanasia was legal, 42% of doctors would be against this method of assisted dying” (p. 34).

Example of Reference list citation:

Kirkey, S. (2013, Feb 9). Euthanasia.   The Montreal Gazette , p A10. Retrieved from Canadian Newsstand Major Dailies database.

MLA In-Text Citations: The Basics

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

Guidelines for referring to the works of others in your text using MLA style are covered throughout the  MLA Handbook  and in chapter 7 of the  MLA Style Manual . Both books provide extensive examples, so it's a good idea to consult them if you want to become even more familiar with MLA guidelines or if you have a particular reference question.

Basic in-text citation rules

In MLA Style, referring to the works of others in your text is done using parenthetical citations . This method involves providing relevant source information in parentheses whenever a sentence uses a quotation or paraphrase. Usually, the simplest way to do this is to put all of the source information in parentheses at the end of the sentence (i.e., just before the period). However, as the examples below will illustrate, there are situations where it makes sense to put the parenthetical elsewhere in the sentence, or even to leave information out.

General Guidelines

• The source information required in a parenthetical citation depends (1) upon the source medium (e.g. print, web, DVD) and (2) upon the source’s entry on the Works Cited page.
• Any source information that you provide in-text must correspond to the source information on the Works Cited page. More specifically, whatever signal word or phrase you provide to your readers in the text must be the first thing that appears on the left-hand margin of the corresponding entry on the Works Cited page.

In-text citations: Author-page style

MLA format follows the author-page method of in-text citation. This means that the author's last name and the page number(s) from which the quotation or paraphrase is taken must appear in the text, and a complete reference should appear on your Works Cited page. The author's name may appear either in the sentence itself or in parentheses following the quotation or paraphrase, but the page number(s) should always appear in the parentheses, not in the text of your sentence. For example:

Both citations in the examples above, (263) and (Wordsworth 263), tell readers that the information in the sentence can be located on page 263 of a work by an author named Wordsworth. If readers want more information about this source, they can turn to the Works Cited page, where, under the name of Wordsworth, they would find the following information:

Wordsworth, William. Lyrical Ballads . Oxford UP, 1967.

In-text citations for print sources with known author

For print sources like books, magazines, scholarly journal articles, and newspapers, provide a signal word or phrase (usually the author’s last name) and a page number. If you provide the signal word/phrase in the sentence, you do not need to include it in the parenthetical citation.

These examples must correspond to an entry that begins with Burke, which will be the first thing that appears on the left-hand margin of an entry on the Works Cited page:

Burke, Kenneth. Language as Symbolic Action: Essays on Life, Literature, and Method . University of California Press, 1966.

In-text citations for print sources by a corporate author

When a source has a corporate author, it is acceptable to use the name of the corporation followed by the page number for the in-text citation. You should also use abbreviations (e.g., nat'l for national) where appropriate, so as to avoid interrupting the flow of reading with overly long parenthetical citations.

In-text citations for sources with non-standard labeling systems

If a source uses a labeling or numbering system other than page numbers, such as a script or poetry, precede the citation with said label. When citing a poem, for instance, the parenthetical would begin with the word “line”, and then the line number or range. For example, the examination of William Blake’s poem “The Tyger” would be cited as such:

The speaker makes an ardent call for the exploration of the connection between the violence of nature and the divinity of creation. “In what distant deeps or skies. / Burnt the fire of thine eyes," they ask in reference to the tiger as they attempt to reconcile their intimidation with their relationship to creationism (lines 5-6).

Longer labels, such as chapters (ch.) and scenes (sc.), should be abbreviated.

In-text citations for print sources with no known author

When a source has no known author, use a shortened title of the work instead of an author name, following these guidelines.

Place the title in quotation marks if it's a short work (such as an article) or italicize it if it's a longer work (e.g. plays, books, television shows, entire Web sites) and provide a page number if it is available.

Titles longer than a standard noun phrase should be shortened into a noun phrase by excluding articles. For example, To the Lighthouse would be shortened to Lighthouse .

If the title cannot be easily shortened into a noun phrase, the title should be cut after the first clause, phrase, or punctuation:

In this example, since the reader does not know the author of the article, an abbreviated title appears in the parenthetical citation, and the full title of the article appears first at the left-hand margin of its respective entry on the Works Cited page. Thus, the writer includes the title in quotation marks as the signal phrase in the parenthetical citation in order to lead the reader directly to the source on the Works Cited page. The Works Cited entry appears as follows:

"The Impact of Global Warming in North America." Global Warming: Early Signs . 1999. www.climatehotmap.org/. Accessed 23 Mar. 2009.

If the title of the work begins with a quotation mark, such as a title that refers to another work, that quote or quoted title can be used as the shortened title. The single quotation marks must be included in the parenthetical, rather than the double quotation.

Parenthetical citations and Works Cited pages, used in conjunction, allow readers to know which sources you consulted in writing your essay, so that they can either verify your interpretation of the sources or use them in their own scholarly work.

Author-page citation for classic and literary works with multiple editions

Page numbers are always required, but additional citation information can help literary scholars, who may have a different edition of a classic work, like Marx and Engels's  The Communist Manifesto . In such cases, give the page number of your edition (making sure the edition is listed in your Works Cited page, of course) followed by a semicolon, and then the appropriate abbreviations for volume (vol.), book (bk.), part (pt.), chapter (ch.), section (sec.), or paragraph (par.). For example:

Author-page citation for works in an anthology, periodical, or collection

When you cite a work that appears inside a larger source (for instance, an article in a periodical or an essay in a collection), cite the author of the  internal source (i.e., the article or essay). For example, to cite Albert Einstein's article "A Brief Outline of the Theory of Relativity," which was published in  Nature  in 1921, you might write something like this:

See also our page on documenting periodicals in the Works Cited .

Citing authors with same last names

Sometimes more information is necessary to identify the source from which a quotation is taken. For instance, if two or more authors have the same last name, provide both authors' first initials (or even the authors' full name if different authors share initials) in your citation. For example:

Citing a work by multiple authors

For a source with two authors, list the authors’ last names in the text or in the parenthetical citation:

Corresponding Works Cited entry:

Best, David, and Sharon Marcus. “Surface Reading: An Introduction.” Representations , vol. 108, no. 1, Fall 2009, pp. 1-21. JSTOR, doi:10.1525/rep.2009.108.1.1

For a source with three or more authors, list only the first author’s last name, and replace the additional names with et al.

Franck, Caroline, et al. “Agricultural Subsidies and the American Obesity Epidemic.” American Journal of Preventative Medicine , vol. 45, no. 3, Sept. 2013, pp. 327-333.

Citing multiple works by the same author

If you cite more than one work by an author, include a shortened title for the particular work from which you are quoting to distinguish it from the others. Put short titles of books in italics and short titles of articles in quotation marks.

Citing two articles by the same author :

Citing two books by the same author :

Additionally, if the author's name is not mentioned in the sentence, format your citation with the author's name followed by a comma, followed by a shortened title of the work, and, when appropriate, the page number(s):

Citing multivolume works

If you cite from different volumes of a multivolume work, always include the volume number followed by a colon. Put a space after the colon, then provide the page number(s). (If you only cite from one volume, provide only the page number in parentheses.)

Citing the Bible

In your first parenthetical citation, you want to make clear which Bible you're using (and underline or italicize the title), as each version varies in its translation, followed by book (do not italicize or underline), chapter, and verse. For example:

If future references employ the same edition of the Bible you’re using, list only the book, chapter, and verse in the parenthetical citation:

John of Patmos echoes this passage when describing his vision (Rev. 4.6-8).

Citing indirect sources

Sometimes you may have to use an indirect source. An indirect source is a source cited within another source. For such indirect quotations, use "qtd. in" to indicate the source you actually consulted. For example:

Note that, in most cases, a responsible researcher will attempt to find the original source, rather than citing an indirect source.

Citing transcripts, plays, or screenplays

Sources that take the form of a dialogue involving two or more participants have special guidelines for their quotation and citation. Each line of dialogue should begin with the speaker's name written in all capitals and indented half an inch. A period follows the name (e.g., JAMES.) . After the period, write the dialogue. Each successive line after the first should receive an additional indentation. When another person begins speaking, start a new line with that person's name indented only half an inch. Repeat this pattern each time the speaker changes. You can include stage directions in the quote if they appear in the original source.

Conclude with a parenthetical that explains where to find the excerpt in the source. Usually, the author and title of the source can be given in a signal phrase before quoting the excerpt, so the concluding parenthetical will often just contain location information like page numbers or act/scene indicators.

Here is an example from O'Neill's  The Iceman Cometh.

WILLIE. (Pleadingly) Give me a drink, Rocky. Harry said it was all right. God, I need a drink.

ROCKY. Den grab it. It's right under your nose.

WILLIE. (Avidly) Thanks. (He takes the bottle with both twitching hands and tilts it to his lips and gulps down the whiskey in big swallows.) (1.1)

Citing non-print or sources from the Internet

With more and more scholarly work published on the Internet, you may have to cite sources you found in digital environments. While many sources on the Internet should not be used for scholarly work (reference the OWL's  Evaluating Sources of Information  resource), some Web sources are perfectly acceptable for research. When creating in-text citations for electronic, film, or Internet sources, remember that your citation must reference the source on your Works Cited page.

Sometimes writers are confused with how to craft parenthetical citations for electronic sources because of the absence of page numbers. However, these sorts of entries often do not require a page number in the parenthetical citation. For electronic and Internet sources, follow the following guidelines:

• Include in the text the first item that appears in the Work Cited entry that corresponds to the citation (e.g. author name, article name, website name, film name).
• Do not provide paragraph numbers or page numbers based on your Web browser’s print preview function.
• Unless you must list the Web site name in the signal phrase in order to get the reader to the appropriate entry, do not include URLs in-text. Only provide partial URLs such as when the name of the site includes, for example, a domain name, like  CNN.com  or  Forbes.com,  as opposed to writing out http://www.cnn.com or http://www.forbes.com.

Miscellaneous non-print sources

Two types of non-print sources you may encounter are films and lectures/presentations:

In the two examples above “Herzog” (a film’s director) and “Yates” (a presentor) lead the reader to the first item in each citation’s respective entry on the Works Cited page:

Herzog, Werner, dir. Fitzcarraldo . Perf. Klaus Kinski. Filmverlag der Autoren, 1982.

Yates, Jane. "Invention in Rhetoric and Composition." Gaps Addressed: Future Work in Rhetoric and Composition, CCCC, Palmer House Hilton, 2002. Address.

Electronic sources

Electronic sources may include web pages and online news or magazine articles:

In the first example (an online magazine article), the writer has chosen not to include the author name in-text; however, two entries from the same author appear in the Works Cited. Thus, the writer includes both the author’s last name and the article title in the parenthetical citation in order to lead the reader to the appropriate entry on the Works Cited page (see below).

In the second example (a web page), a parenthetical citation is not necessary because the page does not list an author, and the title of the article, “MLA Formatting and Style Guide,” is used as a signal phrase within the sentence. If the title of the article was not named in the sentence, an abbreviated version would appear in a parenthetical citation at the end of the sentence. Both corresponding Works Cited entries are as follows:

Taylor, Rumsey. "Fitzcarraldo." Slant , 13 Jun. 2003, www.slantmagazine.com/film/review/fitzcarraldo/. Accessed 29 Sep. 2009. 

"MLA Formatting and Style Guide." The Purdue OWL , 2 Aug. 2016, owl.english.purdue.edu/owl/resource/747/01/. Accessed 2 April 2018.

Multiple citations

To cite multiple sources in the same parenthetical reference, separate the citations by a semi-colon:

Time-based media sources

When creating in-text citations for media that has a runtime, such as a movie or podcast, include the range of hours, minutes and seconds you plan to reference. For example: (00:02:15-00:02:35).

When a citation is not needed

Common sense and ethics should determine your need for documenting sources. You do not need to give sources for familiar proverbs, well-known quotations, or common knowledge (For example, it is expected that U.S. citizens know that George Washington was the first President.). Remember that citing sources is a rhetorical task, and, as such, can vary based on your audience. If you’re writing for an expert audience of a scholarly journal, for example, you may need to deal with expectations of what constitutes “common knowledge” that differ from common norms.

Other Sources

The MLA Handbook describes how to cite many different kinds of authors and content creators. However, you may occasionally encounter a source or author category that the handbook does not describe, making the best way to proceed can be unclear.

In these cases, it's typically acceptable to apply the general principles of MLA citation to the new kind of source in a way that's consistent and sensible. A good way to do this is to simply use the standard MLA directions for a type of source that resembles the source you want to cite.

You may also want to investigate whether a third-party organization has provided directions for how to cite this kind of source. For example, Norquest College provides guidelines for citing Indigenous Elders and Knowledge Keepers⁠ —an author category that does not appear in the MLA Handbook . In cases like this, however, it's a good idea to ask your instructor or supervisor whether using third-party citation guidelines might present problems.

APA follows an author and date of publication model for citing sources in your research paper and are presented as either narrative or parenthetical citations.  The formatting does not vary due to format type, however it may deviate from the norm due to factors such as: number of authors, organization instead of individual author, lack of author, or lack of date.  By providing the standard author and date within your paper, the reader will be able to link the information presented easily to the full citation provided in the reference list.

View examples and explanations on this page or visit the In Text Quick View for more examples.

APA encourages paraphrasing over using direct quotes.  Use direct quotes when:

• Reproducing an exact definition
• Author has said something memorably or succinctly
• When you want to respond to exact wording

When creating a citation for a direct quote, provide author, year and page number for both narrative and parenthetical citations.

Ex.  University of Southern California (2020) "direct quote from author" (p. 4)  OR  "direct quote from author" (University of Southern California, 2020, p. 4).

How to cite specific parts of a source:

Author named in text:

Social historian Richard Sennett (1980) names the tendency to come to terms with difficult experiences a "purification process" whereby "threatening or painful dissonances are warded off to preserve intact a clear and articulated image of oneself and one's place in the world" (p. 11).

Author named in parentheses:

The tendency to come to terms with difficult experiences is referred to as a "purification process" whereby "threatening or painful dissonances are warded off to preserve intact a clear and articulated image of oneself and one's place in the world" (Sennett, 1980, p. 11).

These examples © Duke University Libraries http://library.duke.edu/research/citing/within/apa.html

More than one way to cite:

Flynn (1999) stated in her treatise In a recent treatise on services (Flynn, 1999) In a 1999 treatise, Flynn stated

Subsequent references to same study in same paragraph:

In her treatise on services, Flynn (1999) stated her evaluative methods…Flynn also described

One work, multiple authors

When a work has two authors, always cite both authors' names in your text:

        Significant findings in a study of Los Angeles (McCroskey & O'Keefe, 2000)

When a citation has 3 or more authors, include the last name of the first author, followed by et al. (not italicized), and the year.

        (Nishimoto et al., 1998)

For narrative citations, use the word "and" to separate authors, for parenthetical citations, use an ampersand:

         McCroskey and O'Keefe (2000) studied Los Angeles...          (McCroskey & O'Keefe, 2000)

Groups as authors

First narrative citation: National Association of Social Workers (NASW, 1987)

Subsequent narrative citation: NASW (1987)

First text citation: (National Association of Social Workers [NASW], 1987)

Subsequent text citation: (NASW, 1987)

Works with no authors

Cite the work in your text using the first few words of the reference list entry (usually the title). Put double quotation marks around the title of an article or chapter, and italicize the title of a periodical, book, brochure or report:

The policy stated in the article (“Services for Disabled Children,” 1992)

The policy stated in the book Access to Services for Children (1995)

Specific parts of a source

Indicate the page, chapter, figure, table, or equation at the appropriate point in your text. Give page numbers for quotations, and use the abbreviations for the words page and chapter:

(Aranda & Knight, 1997, p. 344)

(Ell & Castaneda, 1998, chap. 5)

Personal communications

This format applies to emails, messages from nonarchived discussion groups, electronic bulletin boards, personal interviews, telephone conversations, etc. Do not list personal communications in your reference list as they are not recoverable by your reader. In your text, provide initials and surname of communicator and as exact a date as possible.

(M. Flynn, personal communication, September 20, 1999)

Sometimes you'll have multiple works by the same author in the same year. For instance, you may reference a number of tax documents from the same year, which would all be cited with (Internal Revenue Service, 2012).  So how do you differentiate?

In those instances, differentiate sources with a letter after the year. From the example above, the 990 form might be (Internal Revenue Service, 2012a) and the 1040 form would be (Internal Revenue Service, 2012b).  Just make sure the letters stay consistent in your reference list!

Sometimes, you will use a source that you didn't yourself read.  In those cases, the original source came from a secondary source you did read.  APA states that you should use secondary sources sparingly and may occur when "the original work is out of print, unavailable, or available only in a language that you do not understand."

When using secondary sources, indicate it by included "as cited in" as part of your in-text citation

How to Cite Sources

Here is a complete list for how to cite sources. Most of these guides present citation guidance and examples in MLA, APA, and Chicago.

If you’re looking for general information on MLA or APA citations , the EasyBib Writing Center was designed for you! It has articles on what’s needed in an MLA in-text citation , how to format an APA paper, what an MLA annotated bibliography is, making an MLA works cited page, and much more!

MLA Format Citation Examples

The Modern Language Association created the MLA Style, currently in its 9th edition, to provide researchers with guidelines for writing and documenting scholarly borrowings.  Most often used in the humanities, MLA style (or MLA format ) has been adopted and used by numerous other disciplines, in multiple parts of the world.

MLA provides standard rules to follow so that most research papers are formatted in a similar manner. This makes it easier for readers to comprehend the information. The MLA in-text citation guidelines, MLA works cited standards, and MLA annotated bibliography instructions provide scholars with the information they need to properly cite sources in their research papers, articles, and assignments.

APA Format Citation Examples

The American Psychological Association created the APA citation style in 1929 as a way to help psychologists, anthropologists, and even business managers establish one common way to cite sources and present content.

APA is used when citing sources for academic articles such as journals, and is intended to help readers better comprehend content, and to avoid language bias wherever possible. The APA style (or APA format ) is now in its 7th edition, and provides citation style guides for virtually any type of resource.

Chicago Style Citation Examples

The Chicago/Turabian style of citing sources is generally used when citing sources for humanities papers, and is best known for its requirement that writers place bibliographic citations at the bottom of a page (in Chicago-format footnotes ) or at the end of a paper (endnotes).

The Turabian and Chicago citation styles are almost identical, but the Turabian style is geared towards student published papers such as theses and dissertations, while the Chicago style provides guidelines for all types of publications. This is why you’ll commonly see Chicago style and Turabian style presented together. The Chicago Manual of Style is currently in its 17th edition, and Turabian’s A Manual for Writers of Research Papers, Theses, and Dissertations is in its 8th edition.

6 Interesting Citation Facts

The world of citations may seem cut and dry, but there’s more to them than just specific capitalization rules, MLA in-text citations , and other formatting specifications. Citations have been helping researches document their sources for hundreds of years, and are a great way to learn more about a particular subject area.

Ever wonder what sets all the different styles apart, or how they came to be in the first place? Read on for some interesting facts about citations!

1. There are Over 7,000 Different Citation Styles

You may be familiar with MLA and APA citation styles, but there are actually thousands of citation styles used for all different academic disciplines all across the world. Deciding which one to use can be difficult, so be sure to ask you instructor which one you should be using for your next paper.

2. Some Citation Styles are Named After People

While a majority of citation styles are named for the specific organizations that publish them (i.e. APA is published by the American Psychological Association, and MLA format is named for the Modern Language Association), some are actually named after individuals. The most well-known example of this is perhaps Turabian style, named for Kate L. Turabian, an American educator and writer. She developed this style as a condensed version of the Chicago Manual of Style in order to present a more concise set of rules to students.

3. There are Some Really Specific and Uniquely Named Citation Styles

How specific can citation styles get? The answer is very. For example, the “Flavour and Fragrance Journal” style is based on a bimonthly, peer-reviewed scientific journal published since 1985 by John Wiley & Sons. It publishes original research articles, reviews and special reports on all aspects of flavor and fragrance. Another example is “Nordic Pulp and Paper Research,” a style used by an international scientific magazine covering science and technology for the areas of wood or bio-mass constituents.

4. More citations were created on  EasyBib.com  in the first quarter of 2018 than there are people in California.

The US Census Bureau estimates that approximately 39.5 million people live in the state of California. Meanwhile, about 43 million citations were made on EasyBib from January to March of 2018. That’s a lot of citations.

5. “Citations” is a Word With a Long History

The word “citations” can be traced back literally thousands of years to the Latin word “citare” meaning “to summon, urge, call; put in sudden motion, call forward; rouse, excite.” The word then took on its more modern meaning and relevance to writing papers in the 1600s, where it became known as the “act of citing or quoting a passage from a book, etc.”

6. Citation Styles are Always Changing

The concept of citations always stays the same. It is a means of preventing plagiarism and demonstrating where you relied on outside sources. The specific style rules, however, can and do change regularly. For example, in 2018 alone, 46 new citation styles were introduced , and 106 updates were made to exiting styles. At EasyBib, we are always on the lookout for ways to improve our styles and opportunities to add new ones to our list.

Why Citations Matter

Here are the ways accurate citations can help your students achieve academic success, and how you can answer the dreaded question, “why should I cite my sources?”

They Give Credit to the Right People

Citing their sources makes sure that the reader can differentiate the student’s original thoughts from those of other researchers. Not only does this make sure that the sources they use receive proper credit for their work, it ensures that the student receives deserved recognition for their unique contributions to the topic. Whether the student is citing in MLA format , APA format , or any other style, citations serve as a natural way to place a student’s work in the broader context of the subject area, and serve as an easy way to gauge their commitment to the project.

They Provide Hard Evidence of Ideas

Having many citations from a wide variety of sources related to their idea means that the student is working on a well-researched and respected subject. Citing sources that back up their claim creates room for fact-checking and further research . And, if they can cite a few sources that have the converse opinion or idea, and then demonstrate to the reader why they believe that that viewpoint is wrong by again citing credible sources, the student is well on their way to winning over the reader and cementing their point of view.

They Promote Originality and Prevent Plagiarism

The point of research projects is not to regurgitate information that can already be found elsewhere. We have Google for that! What the student’s project should aim to do is promote an original idea or a spin on an existing idea, and use reliable sources to promote that idea. Copying or directly referencing a source without proper citation can lead to not only a poor grade, but accusations of academic dishonesty. By citing their sources regularly and accurately, students can easily avoid the trap of plagiarism , and promote further research on their topic.

They Create Better Researchers

By researching sources to back up and promote their ideas, students are becoming better researchers without even knowing it! Each time a new source is read or researched, the student is becoming more engaged with the project and is developing a deeper understanding of the subject area. Proper citations demonstrate a breadth of the student’s reading and dedication to the project itself. By creating citations, students are compelled to make connections between their sources and discern research patterns. Each time they complete this process, they are helping themselves become better researchers and writers overall.

When is the Right Time to Start Making Citations?

Make in-text/parenthetical citations as you need them.

As you are writing your paper, be sure to include references within the text that correspond with references in a works cited or bibliography. These are usually called in-text citations or parenthetical citations in MLA and APA formats. The most effective time to complete these is directly after you have made your reference to another source. For instance, after writing the line from Charles Dickens’ A Tale of Two Cities : “It was the best of times, it was the worst of times…,” you would include a citation like this (depending on your chosen citation style):

(Dickens 11).

This signals to the reader that you have referenced an outside source. What’s great about this system is that the in-text citations serve as a natural list for all of the citations you have made in your paper, which will make completing the works cited page a whole lot easier. After you are done writing, all that will be left for you to do is scan your paper for these references, and then build a works cited page that includes a citation for each one.

2. Understand the General Formatting Rules of Your Citation Style Before You Start Writing

While reading up on paper formatting may not sound exciting, being aware of how your paper should look early on in the paper writing process is super important. Citation styles can dictate more than just the appearance of the citations themselves, but rather can impact the layout of your paper as a whole, with specific guidelines concerning margin width, title treatment, and even font size and spacing. Knowing how to organize your paper before you start writing will ensure that you do not receive a low grade for something as trivial as forgetting a hanging indent.

3. Double-check All of Your Outside Sources for Relevance and Trustworthiness First

Collecting outside sources that support your research and specific topic is a critical step in writing an effective paper. But before you run to the library and grab the first 20 books you can lay your hands on, keep in mind that selecting a source to include in your paper should not be taken lightly. Before you proceed with using it to backup your ideas, run a quick Internet search for it and see if other scholars in your field have written about it as well. Check to see if there are book reviews about it or peer accolades. If you spot something that seems off to you, you may want to consider leaving it out of your work. Doing this before your start making citations can save you a ton of time in the long run.

Finished with your paper? It may be time to run it through a grammar and plagiarism checker , like the one offered by EasyBib Plus. If you’re just looking to brush up on the basics, our grammar guides  are ready anytime you are.

Academic Skills: Writing: Reusing Your Work and Citing Yourself

As you progress in your Walden program, you may find that you research and write about a topic more than once. This is typical as you engage with key concepts and specialize in your field of study. See the information and best practices on this page to ensure you follow APA citation guidelines and Walden policy if you plan to reuse past written work.

Your Published Writing

If you have published your writing outside of the Walden classroom—in a journal or even in a local newsletter or blog—and would like to reuse portions of it or refer to the findings or ideas in that work, you will need to cite yourself.

Follow APA’s guidelines for citing and referencing published works.

Your Previous Coursework

If you are considering reusing your previously submitted Walden coursework in a new course or term, review the following best practice and policy sections.

Best Practices for Reusing Work

• During your studies at Walden, you may write on the same topic for a second, third, or fourth time; regardless, your writing should reflect new approaches and insights into that topic to demonstrate intellectual growth.
• Your writing submitted for previous Walden courses will show up in the Turnitin Similarity Report when reused. Contact your faculty if you plan to reuse your work to avoid concerns about possible plagiarism. Additionally, you could cite your unpublished writing (see How to Cite Your Unpublished Work below).
• Your faculty for your current course can guide you about whether reusing your previous writing seems appropriate for a particular assignment or writing task.

Walden University’s Policy on Reusing Work

The following comes from the Walden Student Code of Conduct :

Walden Students’ Use of Their Own Scholarly Work

• Students may reuse their work without an expectation that previously awarded grades or credit will attach to the new assignment. Any work previously published by the student must be appropriately cited if reused. 
• Field Experience Exception: Any assignments or documentation submitted related to field experience (work, hours, client or patient logs, etc) must be new, current, accurate, and relate to clients or patients seen during the term and in direct reference to the assignment.

How to Cite Your Unpublished Work

Although not required in the policy above, in rare instances, you may need to or want to cite your unpublished Walden coursework.

If you cite or quote your previous work, treat yourself as the author and your own written document as the source. For example, if Marie Briggs wanted to cite a paper she wrote at Walden in 2022, her citation might look like this:

Briggs (2022) asserted that previous literature on the psychology of tightrope walkers was faulty in that it "presumed that risk-taking behaviors align neatly with certain personality traits or disorders" (p. 4).

And in the reference list:

Briggs, M. (2022). An analysis of personality theory [Unpublished manuscript]. Walden University.

How To Do In-Text Citations with Multiple Authors in APA Format

APA (or American Psychological Association) Style   was introduced in 1929 to establish a consistent style guide for scientific writing. It sought to make scientific works easier to read and understand. However, the style guidelines have expanded to include many disciplines, such as the humanities and health care.

The APA’s Publication Manual does not cover the general writing style rules in other editorial style guides, such as the MLA Handbook . APA Style seeks to create uniformity of common writing styles relevant to behavior and social sciences primarily.

Consistent formatting allows the reader to engage with the presented ideas rather than be distracted by the author’s personal formatting preferences. It also helps readers quickly review the document for references and sources to aid their research. Using APA Style keeps authors transparent by providing rules about citing their sources and giving credit for others’ ideas.

How to do in-text citations in APA

• Understanding “et. al.” usage in APA

Citing multiple authors in APA

• In-text citations for various author types in APA

Best practices and common mistakes

APA Style allows writers to credit and cite other works appropriately and avoid plagiarism through in-text citations. APA Style uses the author–date citation system, which requires notations to be included within the document to reference ideas, paraphrases and quotations from other bodies of work. Each in-text citation within the paper (or chart, footnote or figure) briefly identifies the cited work and guides the reader to a longer list of cited sources at the end of the document, called the reference list.

In-text citations can be written within a paper parenthetically or narratively. Both include the same information: the author’s last name and the publication date.

• Parenthetical citation : Great falls can be caused by sitting on tall walls (Dumpty, 1797).
• Narrative citation : Dumpty (1797) claims that great falls can be caused by sitting on tall walls.
• Reference list entry: Dumpty, Humpty (1797). Humpty Dumpty Sat on a Wall. Nursery Rhymes, 100.

APA Style requires citations to conform to a set of guidelines , which includes proper spelling of author names, consistency between the in-text citation information and its reference list entry and rules about crediting all facts and figures mentioned – especially those which are not common knowledge.

Understanding “et al.” usage in APA

Et al. is an abbreviation used to indicate multiple people. It’s the abbreviated version of “et alia,” a neutral plural version of “and others.” Most commonly, et al. indicates more than one contributor, such as multiple authors or editors, in a work.

In APA Style citations, et al. is used to indicate a cited work with three or more authors and serves as a way to condense the in-text citation to avoid confusion and unnecessary length. An APA in-text citation with three or more authors will include only the first author’s name plus “et al.” in every citation.

Citing multiple authors in APA Style is similar to MLA Style . For one or two authors, list the last name(s) followed by the year of publication. 

• One author: (Beyonce, 1997)
• Contributors: Daryl Hall and John Oates

To cite three or more authors using APA Style, use only the first author’s last name listed, plus “et al.” 

• Contributors: Earth, Wind and Fire

When two separate sources have the same abbreviated et al. form , spell out as many last names as needed to distinguish the sources from each other. It may include two last names followed by et al.

Similarly, when the first authors of separate sources share the same last name but have different initials, use their first initials in the in-text citations.

• Beyonce Knowles & Solange Knowles

In-text citation for various author types in APA

You may face a challenging situation where you must cite a group author , such as an institution or university, rather than a list of authors’ names. In this instance, you’ll list the group or organization.

• Group author: (Furman University, 2020)

If the group also has an abbreviation to its name, you may note the first and subsequent citations differently to be as concise as possible.

• Group author with abbreviation – 1st citation: (American Psychological Association [APA], 2024)
• Group author with abbreviation – 2nd citation : (APA, 2024)

The most common mistake when citing sources is forgetting to cite a source. One way to ensure you include all required sources is to document and manage your sources as you use their ideas within the document. This may mean you create the citations as you conduct your research, create your outline or type the final paper.

Some applications exist to help you manage and document citations, including EasyBib , Mendeley , EndNote and Zotero . Depending on your writing style, these applications can help you create citations, save your research sources, annotate documents and format references. 

Regarding best practices for in-text citations in APA Style, it’s good practice to proofread your citations and reference list together. When citing multiple authors, ensure all spellings are accurate and consistent throughout the document and reference list. Refer to the APA Style Publication Manual and other guideline reference documents to confirm your citing within the latest citation guidelines.

Giving credit to other authors who have shaped your research and ideas is incredibly important. You can do so without risking plagiarism accusations through in-text citations that are marked and referenced. Not only does it provide you with an honest and accurate reputation, but it also helps your readers gain more valuable knowledge from other sources.

Citing sources should not discourage you from sharing your knowledge within academic writing. Sooner or later, you’ll become a pro at in-text citations in APA style! The more you write, the more familiar you’ll become with the guidelines; you’ll no longer need to reference the style guides for help.

How To Do In-Text Citations in MLA Format: A Quick Guide for Students

U.S. Constitution.net

How to cite this site – the u.s. constitution online – usconstitution.net, how to cite this site.

Jump to: Citing the Constitution

It is very important when writing a paper for a school project (at any level, from elementary school to graduate school) to properly cite your sources. Where did you find your information? Citations are placed in the text as footnotes or endnotes, and/or placed at the end of your work in a bibliography. This page will handle a few different possibilities. The first is to answer the question “How do I cite a page on this site?” or, as I like to say, “How to cite the site.”

There are two main areas that someone might wish to cite on this site. The first is one of the pages found on the site. Several are simply electronic copies of historical documents, while others are research pages or opinion pages. You should be able to discern which is which pretty easily. Unless the information is a copy of a historical document, and unless otherwise noted, everything here is written by the Webmaster, Steve Mount.

Here is a standard way to cite an HTML page published on the Internet, according to the Columbia Guide to Online Style :

• Mount, Steve. “Constitutional Topic: Martial Law.” USConstitution.net. 30 Nov 2001. http://www.usconstitution.net/consttop_mlaw.html (3 Dec 2001)

Specifically, the data is as follows: Author, Title, Site, Modification Date (found at the bottom of every page), URL, and the date the page was accessed. The two dates are critical because of the changeable nature of the Web.

The next citation uses the APA format. This standard comes from the American Psychological Association, and is often used in psychology and other social sciences:

• Mount, S. (2010). Constitutional topic: due process. Retrieved February 23, 2011 from http://www.usconstitution.net/consttop_duep.html

Specifically, the data is as follows: Author, Modification Year (found at the bottom of every page), page title, the date the page was accessed, and the URL.

Finally, the MLA style is often used. This style comes from The Modern Language Association. With this style, citations are noted in the text and full references are given in a Works Cited list at the end of the paper.

• Inline: (Mount)
• Works Cited: Mount, Steve. “Constitutional Topic: The Census.” USConstitution.net . 3 Jan. 2011. 27 Feb. 2011 .

Specifically, the data is as follows: Author, Title, Site, Modification Date, thee date the page was accessed, and URL.

The second source of information is this site’s Message Boards. The primary information available in the Message Boards is opinion. Because the opinions are those of the posters, the citation of a message needs to include the name or handle of the poster. Here is an example, in the Columbia Style, for a posting from the Classic Boards on this site:

• Ian. “Re: Question regarding Law.” 2 Dec 2001. USConstitution.net Q&A Board. http://www.usconstitution.net/cgi-bin/wwwbmsg.cgi?const&001280.wwb (3 Dec 2001)

The data is as follows: Poster, Subject, Date Posted, Board Name, URL, and date accessed.

All posts created after November 2003 used the new messaging software. Here is an example for a posting using the new software:

• Andy. “Re: Impeach Scalia?” 5 Feb 2004. Debate Archives. http://www.usconstitution.net/yabb/YaBB.cgi?board=debarch;action=display;num=1077548457 (25 Feb 2004)

Citing the U.S. Constitution

Another common question involves how to cite the Constitution itself. There are two forms, a long form and a short form. In a legal document, the short form will suffice in all instances, whereas in a non-legal paper, the long form should be used once, and the short form can be used thereafter.

• “The Constitution of the United States,” Article 1, Section 8, Clause 5.
• “The Constitution of the United States,” Amendment 5.

Short Form:

• U.S. Const. art. I, § 8, cl. 5.
• U.S. Const. am. 5.

In place of the “§” symbol, the abbreviation “sect.” can be used. In a paper dealing primarily with the Constitution, there is no need to mention “U.S. Const.”
