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 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.

How to cite a quote in APA, MLA and Chicago

Every time you quote, you must cite the source correctly. This looks slightly different depending on the citation style you’re using. Three of the most common styles are APA, MLA, and Chicago.

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 periods and commas are placed after the citation, not within the quotation marks.

Citing a quote in MLA style

An MLA in-text citation includes only the author’s last name and a page number. As in APA, it can be parenthetical or narrative, and a period (or other punctuation mark) appears after the citation.

Citing a quote in Chicago style

Chicago style uses Chicago footnotes to cite sources. A note, indicated by a superscript number placed directly after the quote, specifies the author, title, and page number—or sometimes fuller information.

Unlike with parenthetical citations, in this style, the period or other punctuation mark should appear within the quotation marks, followed by the footnote number.

Introducing quotes

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).

Quotes within quotes

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 single (instead of double) 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 double quotation marks.

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.

Shortening or altering a quote

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 verb 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 italicize 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 capitalization made to ensure the quote fits the style of your text.

Block quotes

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 period, the citation appears after the period.

When should I use quotes?

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

However, there are some situations in which quoting is 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.
