Mastering MLA quotations is the difference between a clumsy summary and a polished research paper that commands respect. When you integrate external evidence cleanly, your argument gains authority without losing its personal voice. The Modern Language Association (MLA) style relies on parenthetical in-text citations paired with a complete Works Cited page, designed to guide readers directly to your sources with minimal friction.
Whether you're writing for a freshman composition class or submitting a capstone paper in the humanities, getting the mechanics right matters. This guide breaks down the exact rules for short quotes, block quotes, altering text safely, and punctuating parenthetical citations correctly every single time.
Mechanics of In-Text Citations in MLA
The core of MLA formatting is the parenthetical citation placed immediately after your quoted or paraphrased material. This brief reference points the reader to the corresponding bibliographic entry at the end of your document.
When your sentence names the author directly, you don't need to repeat their name in the parentheses. You only need the page number.
- Example: As literary critic Lesley Brill observes, "Hitchcock's films tend to start in public locations and move to more private spaces" (195).
When your sentence does not name the author, you must include both the author's last name and the exact page number inside the parentheses, with no punctuation separating them.
- Example: Cinematic studies show that "Hitchcock's films tend to start in public locations and move to more private spaces" (Brill 195).
Never include the abbreviation "p." or the word "page" inside the parentheses. Just supply the Arabic numeral.
Short Quotations vs. Block Quotations
The length of the text you want to include determines how you format the quotation on the page. MLA divides evidence into short prose and long block quotes based on a specific line threshold.
Short Quotations (Four Lines or Fewer)
For prose that spans four lines or fewer in your typed document, embed the text directly into your running sentence. Enclose the borrowed words in double quotation marks and place your parenthetical citation after the closing quotation mark, but before the terminal period of the sentence.
- Example: Cultural historians note that "the shift toward digital archives has fundamentally altered how students interact with primary texts" (Vargas 42).
Long Quotations (More Than Four Lines)
When a quote extends beyond four lines of prose, you must format it as a block quote. Block quotes remove the need for quotation marks and isolate the passage to give the reader visual breathing room.
To set up a block quote correctly:
- Introduce the source with a complete sentence followed by a colon.
- Start a new line and indent the entire quotation one inch from the left margin.
- Keep the text double-spaced, exactly like the rest of your paper.
- Place the parenthetical citation after the final punctuation mark of the quoted sentence—this is the opposite of a short quote rule.
- Example: Writing about the evolution of scholarly communication, researcher Marcus Thorne notes: The modern academic landscape demands an unprecedented level of transparency. Researchers can no longer rely on obscure archival references that take weeks to verify. Open-access repositories have democratized knowledge, forcing a complete overhaul of how we evaluate academic credibility and institutional prestige. (112)
Modifying Quotes: Ellipses and Brackets
You rarely need an entire quoted paragraph to make your point. When you trim unnecessary words or clarify ambiguous pronouns, you must follow strict modification rules.
Using Ellipses to Omit Text
If you leave out a word, phrase, or sentence from the middle of a quote, indicate the omission with three spaced periods ( . . . ). Make sure the remaining sentence still reads grammatically.
- Original: "The committee discovered that the funding model, despite initial skepticism, was entirely sustainable."
- Modified: "The committee discovered that the funding model . . . was entirely sustainable" (Chen 88).
Using Brackets to Add Clarity
If a quote contains a pronoun that lacks context without the original paragraph, use square brackets to insert the clarifying noun. Never use parentheses for your own insertions.
- Example: The report stated that "it [the municipal water system] failed inspection twice last year" (O'Connor 14).
If you spot a genuine spelling or grammatical error in the original source, leave the error intact and insert sic in italicized brackets right after it to signal to your reader that the mistake belongs to the original author, not you.
- Example: The author claimed that "the phenomenom [sic] is entirely unprecedented" (Garcia 23).
Common Mistakes to Avoid
Even seasoned researchers slip up when mixing punctuation marks with parenthetical citations. Keep these common pitfalls in mind:
- Punctuation placement: For short quotes, commas and periods go inside the quotation marks, while the parenthetical citation sits outside. Semicolons and colons always go outside the quotation marks.
- Over-quoting: Never let someone else's words do your heavy lifting. A good rule of thumb is that your own analysis should always outweigh the combined length of your block and short quotes.
- Forgetting the Works Cited link: Every single in-text citation must have a matching entry on your MLA Works Cited page, formatted with a hanging indent and alphabetized by the author's last name.
Frequently Asked Questions
What do I do if my source has no page number?
If you are citing a web page or digital article that lacks pagination, omit the page number entirely in your parenthetical citation. If the source uses numbered paragraphs or sections, use those instead (e.g., par. 4).
How do I cite a source with two or three authors?
Include all authors' last names in the order they appear on the title page. For two authors, use and between them (Smith and Jones 45). For three authors, separate them with commas and and before the last name (Smith, Jones, and Davis 45).
How do I handle a quote within a quote?
When the author you are quoting includes a quote from someone else, use single quotation marks inside your double quotation marks to designate the nested quote. In your parenthetical citation, add the abbreviation qtd. in before the final source (qtd. in Miller 78).
Where should the period go for a block quote?
Unlike short quotes, block quote citations sit after the final punctuation mark of the quoted sentence, with no punctuation following the closing parenthesis.
