Why Citations Matter
Every time you use someone else's ideas, words, or data in your writing, you must give them credit. Citations serve three purposes: they give credit to the original thinker, they allow your reader to verify or explore your sources, and they protect you from plagiarism — presenting others' work as your own, which is an academic integrity violation with serious consequences.
MLA (Modern Language Association) format is the standard citation style for the humanities — literature, language, cultural studies, and related fields. It is used in high school and college writing worldwide and emphasizes the author-text relationship, which is why its in-text citations highlight the author's last name and page number rather than a year of publication (which APA, the science-oriented style, uses instead).
MLA 9th edition (released 2021) introduced a flexible "container" framework that simplifies citing any source type with one unified structure. Understanding that framework is the key to MLA — once you grasp it, you can cite any source without memorizing separate rules for each type.
The Six Core Concepts of MLA
Every time you quote, paraphrase, or summarize a source in the body of your paper, you place a parenthetical citation at the end of the sentence. The citation contains the author's last name and the page number (no comma between them), placed before the final period.
If you name the author in your sentence (a "signal phrase"), you omit the name from the parentheses and include only the page number: Orwell argues that the pigs "became more human" (131).
For sources without page numbers (websites, e-books, videos), use the author's last name alone: (Morrison). If there is no author, use a shortened version of the title: ("Climate Change Effects").
MLA 9 uses a "container" framework: the source exists inside a larger container, which may itself exist inside another container. A journal article (source) appears in a journal (container 1), which may appear in a database like JSTOR (container 2). Each container has its own title, publisher, date, and location details.
The nine core elements of an MLA Works Cited entry, in order, are: Author. Title of Source. Title of Container, Other Contributors, Version, Number, Publisher, Publication Date, Location.
Not every element applies to every source — simply omit missing elements. The period-comma punctuation pattern is consistent: a period after the author, a comma after the container title, a comma between subsequent container elements.
Books are the simplest entry type because they are rarely inside a second container. The format is: Last name, First name. Title of Book. Publisher, Year.
Note: the first author is inverted (Last, First); subsequent authors are in normal order (First Last). "et al." replaces three or more additional authors.
Articles live inside a container (the journal), so the format becomes: Last name, First name. "Title of Article." Name of Journal, vol. number, no. number, Year, pp. page range.
The database (JSTOR) becomes the second container. Include a DOI (digital object identifier) if available — it is more stable than a URL. Use the full DOI as a hyperlink starting with https://doi.org/.
Websites often lack page numbers and sometimes lack authors or publication dates. Include as many of the nine core elements as are available. Always include an access date for web sources that may change, using the format: "Accessed Day Month Year."
For months: abbreviate all months except May, June, and July. Use "Sept." not "Sep." MLA abbreviates months this way: Jan., Feb., Mar., Apr., Aug., Oct., Nov., Dec.
The Works Cited page appears at the end of the paper on a new page. It is titled "Works Cited" (centered, not bold or italicized) and lists sources alphabetically by the first word of the entry (usually the author's last name). Each entry uses a hanging indent: the first line is flush left and all subsequent lines are indented half an inch.
| Rule | Detail |
|---|---|
| Page title | "Works Cited" — centered, same font, not bold/italic |
| Order | Alphabetical by first word of entry (ignore "A," "An," "The") |
| Indentation | Hanging indent — first line flush, subsequent lines indented 0.5 in. |
| Spacing | Double-spaced throughout, no extra space between entries |
| Titles | Books and journals: italicized. Articles and chapters: "in quotation marks." |
| Page numbers | Continue from the last page of the paper |
Practice Problems
1. Write the in-text citation for this situation: You are quoting page 47 of a book by Sandra Cisneros. You have already named Cisneros in your sentence.
2. Create a Works Cited entry for: a book called "To Kill a Mockingbird" by Harper Lee, published by HarperCollins in 2002.
3. You are citing a website article: "The Science of Sleep" by Maya Rosenblatt, published on March 12, 2023, on Scientific American at www.scientificamerican.com/article/the-science-of-sleep. You accessed it on January 5, 2024.
4. What is wrong with this in-text citation? "According to researchers, social media use is linked to depression." (Smith, 2021, p. 34).
5. A journal article has three authors: David Kim, Laura Patel, and Steven Okonkwo. How do you cite them in the Works Cited entry and in an in-text citation?
5 Common MLA Mistakes
Mixing Up MLA and APA
APA (American Psychological Association) puts the year in parenthetical citations: (Smith, 2021, p. 34). MLA does not use the year in in-text citations at all — only author and page: (Smith 34). Mixing the two creates a hybrid that satisfies neither style. If in doubt, check which style your assignment requires before you begin writing.
Forgetting Hanging Indents
A Works Cited entry that looks like a regular paragraph (all lines flush left) violates MLA format. In Word, create a hanging indent with Format > Paragraph > Indentation > Special > Hanging. In Google Docs, use Format > Align and Indent > Indentation options > Special indent > Hanging > 0.5 inches. This is one of the easiest points to lose on a graded assignment — and one of the easiest to fix.
Italicizing Article Titles or Quoting Book Titles
The rule is consistent: a source that is a complete, standalone work (book, journal, film, website) gets an italic title. A source that is part of a larger container (article, chapter, poem, episode) gets quotation marks. "The Great Gatsby" is wrong — it is a standalone novel: The Great Gatsby. "To Build a Fire" is wrong — it is a short story inside a collection: "To Build a Fire."
Using Wikipedia as a Citable Source
Wikipedia is an excellent starting point for background research — its sources section at the bottom of each article points to citable primary and secondary sources. However, Wikipedia itself is user-edited and not peer-reviewed, which is why most academic instructors do not accept it as a cited source. Follow the footnotes and citations on Wikipedia pages to find the original, citable sources.
Citing the Source in Works Cited but Not In-Text (or Vice Versa)
Every source in your Works Cited must have at least one corresponding in-text citation in the paper. Every in-text citation must have a corresponding Works Cited entry. The two lists must match perfectly: if you cite (Morrison 12) in the paper, "Morrison" must be the first word of an entry on your Works Cited page. Audit both lists before submitting.
