MLA Citation Guide: MLA 9th Edition Format Made Clear
MLA is the citation style of literature, languages, and the rest of the modern humanities. The current edition is the ninth, released April 2021, and almost every rule below is keyed to that revision. If your humanities course asks for “MLA,” this is the style your instructor expects.
The shortest version of MLA: author and page in the text, full entry on the Works Cited page, title case throughout, nine core elements in a fixed order, hanging indent, double-spaced.
What MLA is and when you’ll use it
MLA was the dominant style of the American humanities classroom for sixty years before it absorbed the rest of the modern languages and named itself after them. The Modern Language Association published the first MLA Style Sheet in 1951; the current edition is the ninth, released April 2021. The underlying logic shifted at the eighth edition and was refined in the ninth: instead of cataloguing rules per source type, MLA hands you nine core elements and asks you to assemble each entry from those. The result is a single shape that fits a book, a journal article, a film, a tweet, or a podcast.
The MLA Handbook (Modern Language Association, 2021) is the authoritative reference, and most of what you’ll find online is a summary of it. Where this guide states a rule, the rule comes from the ninth edition.
You’ll be asked for MLA in literature, foreign-language, comparative literature, classics, film, and most humanities composition courses. Some media and cultural studies programs use it too. If your assignment rubric says “MLA” without a number, assume the ninth edition — anything older has been out of date since spring 2021.
In-text citations
MLA’s in-text citation is author–page: the author’s surname and the page number where the cited material appears, with no comma between them and no abbreviation in front of the page. The reader scans the parenthetical, then turns to the Works Cited page for the full entry. The surname in the parenthetical must match the first surname in the Works Cited entry exactly.
One author
Cite the surname and the page. If the author’s name appears in the sentence, only the page number goes in the parenthetical.
Parenthetical: Working memory operates less like a storage bin and more like a workspace (Chen 47).
Narrative: Chen argues that working memory operates less like a storage bin and more like a workspace (47).
No year, no comma, no p. The format is (Surname Page) and that is the whole template.
Two authors
Both surnames appear in every citation, joined by and — not an ampersand. Order matches the Works Cited entry.
Parenthetical: (Lin and Patel 155)
Narrative: Lin and Patel argue that cross-modal attention appears earlier than developmental psychology has typically allowed (155).
Three or more authors
Use the first author’s surname followed by et al. (set in roman in MLA — no italics) on every citation, including the first. There is no “spell them all out the first time” phase the way some older style guides require.
Every citation: (Goldstein et al. 88)
If the source is by Goldstein, Ramanathan, and O’Connor, the in-text citation is (Goldstein et al. 88) from the first appearance forward. The full author list appears only in the Works Cited entry.
Organization as author
Treat a corporate or government author like a personal one. Use the full organization name on first mention; if the name is long, introduce a short form and use it thereafter.
First: (United States, Department of Education, Institute of Education Sciences 12)
Subsequent: (Inst. of Education Sciences 12)
A widely known acronym can be used from the start; an obscure one needs the full form on first mention.
No named author
When a work has no identified author, the title moves into the author slot. Use a shortened form of the title in the parenthetical, italicized for standalone works (books, films, reports) and in quotation marks for shorter pieces (articles, chapters, web pages).
Web article with no author: (“Cognitive Load” par. 6)
Book or report with no author: (Reading Proficiency and Learning Loss 14)
Multiple works by the same author
When your Works Cited page lists more than one work by the same author, the in-text citation needs a short title to point the reader to the right entry. Place a comma between the surname and the short title, and the page number after the title with no comma.
Example: (Chen, Architecture 47) vs. (Chen, “Workspace” 12)
The short title matches the first significant word or words of the full title in the Works Cited entry.
Direct quotes
Direct quotations use the same (Author Page) parenthetical you’d use for paraphrase — MLA does not require a separate format for quotes. Place the citation after the closing quotation mark and before the sentence’s terminal punctuation.
Short quote: Working memory is “a flexible mental workspace, not a fixed bin of slots” (Chen 47).
Prose quotations that run more than four lines in your paper become block quotes: indented half an inch from the left margin, no quotation marks, double-spaced like the rest of the paper. The parenthetical follows the closing punctuation of the block, with no period after the parenthetical. For poetry, the threshold is three or more lines of verse. A prose quotation of exactly four lines is not a block quote — the cutoff is “more than four,” and the MLA Handbook (Modern Language Association, 2021) is explicit about that.
Citing multiple sources at once
When a single parenthetical points to multiple sources, separate them with semicolons. Order them as the sense of the passage requires — there is no fixed alphabetical rule the way APA insists on.
Example: Three studies converge on the pattern (Chen 47; Goldstein et al. 88; Lin and Patel 155).
Sources without page numbers
Web pages, videos, and most digital-only sources don’t have pages. Cite them anyway: use a paragraph number with par. if the source numbers its paragraphs, a timestamp for video or audio (02:14:55), or a named section heading. If none is available, the parenthetical is just the surname.
With paragraph numbers: Alvarez argues that comprehension “outruns vocabulary growth” in elementary readers (par. 4).
With no available locator: (Alvarez)
Do not invent a page number by counting paragraphs or screens. MLA 9 prefers an honest omission to a fabricated locator.
Works Cited page format
The Works Cited page goes on its own page at the end of the paper, with the words Works Cited centered at the top — not bolded, not underlined, just centered in the same font as the rest of the paper. This is a small but visible difference from APA’s bold “References.” Every source cited in the body appears here, and every entry here is cited at least once in the body.
Entries are alphabetized by the first author’s surname (or, for a source with no named author, by the first significant word of the title — ignoring A, An, The). The page is double-spaced throughout, and each entry uses a hanging indent of half an inch.
The heart of MLA 9 is the core elements approach. Rather than memorize a separate template for every kind of source you might cite, you assemble each Works Cited entry from these nine elements, in this order:
- Author.
- Title of source.
- Title of container,
- Other contributors,
- Version,
- Number,
- Publisher,
- Publication date,
- Location.
Read the punctuation marks at the end of each element as carefully as the words. The period after Author and Title of source is mandatory; the commas after Title of container through Publication date are mandatory; the period after Location closes the entry. If an element doesn’t apply to your source — most sources skip several — leave it out and continue with the punctuation of the next element that does apply.
The container concept is the part that catches people off guard. A container is the larger work that holds the thing you’re citing. A book is its own container (the entry has one). A journal article sits inside the journal (container 1) and, if you accessed it through a database, also inside the database (container 2). Drop container 2 from a database-retrieved article and you’ve half-cited the source.
For the author element, invert the first author’s name (surname first); present subsequent authors in normal order. For three or more authors, name only the first and add et al. For online sources, the MLA Handbook (Modern Language Association, 2021) strips the http:// or https:// prefix from URLs in the Works Cited entry. DOIs are the exception — they keep the https://doi.org/ prefix because the prefix is part of the canonical identifier. Use a DOI in place of a URL whenever a DOI exists. Add an access date for sources without a stable publication date — live web pages, social media posts, frequently updated reference articles — by appending Accessed 20 May 2026. after the URL. Access dates are optional but recommended whenever the source could change after you read it.
Capitalization is title case across the board: article titles, book titles, journal titles, container titles. This is the cleanest difference from APA, which mixes sentence case and title case across the same reference. In MLA you only need to remember one rule.

A few details to notice. Book and journal titles are italicized; article and chapter titles take quotation marks. The journal entry collapses three authors to Goldstein, Aaron, et al. on the Works Cited page — the first author inverted as surname-then-given-name, followed by et al. — just as the in-text citation uses Goldstein et al. MLA 9 applies the rule to both. The edited-volume chapter names the editor in normal order with edited by, not the parenthetical (Ed.) APA uses. The website entry includes an access date because the page is on a live publication; the journal article doesn’t because its publication date is fixed. The government report inverts the corporate author so the larger entity comes first, making the entry sortable under U. If you’re entering one of these into the generator, the tool will assemble the punctuation, italics, and hanging indent for you, but the underlying logic is what’s shown above.
Common mistakes
These five errors account for most of the marks students lose on MLA assignments. Each shows the wrong version above the right one.
Comma between the author and the page number. Wrong: (Chen, 47) Right: (Chen 47)
MLA’s parenthetical has no internal comma. The comma is APA’s convention; if you’ve taken classes in both styles, the muscle memory will fight you.
Including the year in the parenthetical. Wrong: (Chen 2021, 47) Right: (Chen 47)
The year lives in the Works Cited entry, not in the parenthetical. Author–page is the whole signature.
Forgetting the second container for a database-retrieved article. Wrong: … Journal of Cognitive Development, vol. 19, no. 2, 2024, pp. 87–104. Right: … Journal of Cognitive Development, vol. 19, no. 2, 2024, pp. 87–104. JSTOR, https://doi.org/10.1037/cogdev0000412.
If you accessed the article through a database, name the database as container 2 and italicize it; the DOI or URL goes after. When the DOI is the only access point — for instance, an open-access article retrieved directly from the publisher — container 2 may be omitted.
Using sentence case for the article title. Wrong: “Sleep consolidation effects on procedural learning in adolescents.” Right: “Sleep Consolidation Effects on Procedural Learning in Adolescents.”
MLA uses title case everywhere. Sentence case is APA’s habit, not MLA’s.
Block-quoting a four-line passage. Wrong: Indenting a four-line prose quotation as a block. Right: Treat anything four lines or shorter as a run-in quotation with quotation marks; block-quote only what runs more than four lines.
The threshold is more than four, not four or more. A five-line quotation belongs in a block; a four-line quotation belongs in your paragraph.
What’s new in MLA 9
The ninth edition is a refinement of the eighth, not a reinvention. The eighth edition (2016) introduced the core elements approach; the ninth (2021) tightened the rules, expanded the worked-example library, and added several new sections. If you’ve worked with MLA 8, these are the differences that matter.
Core elements approach, clarified. MLA 9 walks through edge cases and ambiguous source types in much more depth. The order and the punctuation didn’t change.
Annotated bibliography guidance. MLA 9 adds explicit formatting rules for annotated bibliographies — placement of the annotation under the Works Cited entry, indentation, expected length. Earlier editions left those details to instructors.
Inclusive language section. The ninth edition adds a chapter on inclusive language, covering gender-neutral pronouns, identity-first vs. person-first language, and references to race and ethnicity. The chapter is descriptive rather than prescriptive, but it gives writers a vocabulary for choices earlier editions didn’t address.
More worked examples for digital and emerging sources. Tweets, video games, YouTube videos, podcasts, web comics, and other born-digital genres all get explicit worked examples. MLA 8 mostly told you to apply the core elements yourself; MLA 9 shows you.
Explicit treatment of in-class materials. A guest lecture, a class discussion, a slide deck, a handout — MLA 9 has a worked example for each. Earlier editions treated these as personal communications and offered little detail.
DOIs preferred over URLs. MLA 8 accepted either; MLA 9 makes the preference explicit. When both exist, use the DOI. When only a URL exists, strip the http:// or https:// prefix — the MLA 9 convention is to omit the protocol on plain URLs but keep https://doi.org/ on DOIs.
The remaining mechanics — author–page in-text citations, the nine core elements in fixed order, alphabetized Works Cited entries with hanging indents, double-spacing, title case throughout — are unchanged from MLA 8. The ninth edition deepens and clarifies; it does not rebuild.
