What is MLA format?
MLA (Modern Language Association) format is the citation and formatting standard used in humanities disciplines: literature, linguistics, languages, rhetoric, cultural studies, and related fields. The MLA Handbook (9th edition, 2021) is the current standard. MLA uses author-page in-text citations (Smith 45) and a Works Cited list at the end of the paper. Unlike APA, MLA format requires a header with the author's name, instructor, course, and date in the top-left corner. MLA is primarily used in undergraduate coursework and humanities journals, though some journals have their own citation adaptations.
MLA (Modern Language Association) format is the citation and manuscript standard for humanities disciplines — literature, linguistics, languages, cultural studies, rhetoric, and related fields. Whether you are writing a seminar paper or submitting to a humanities journal, getting MLA right matters. Editors who work with MLA daily notice formatting errors immediately, and journals may desk-reject manuscripts that do not follow their submission guidelines.
MLA 9th Edition Formatting Rules
MLA 9th edition (2021) sets specific requirements for both manuscript presentation and the citation system:
- Margins: 1 inch on all sides.
- Font: Times New Roman 12pt (or a legible equivalent).
- Spacing: Double-spaced throughout the entire document, including the Works Cited list. No extra space between entries.
- Manuscript header: Your last name, instructor name, course, and date (e.g., 15 April 2026) in the upper-left corner of the first page. MLA does not use a separate title page for most papers.
- Running header: Last name and page number (e.g., Smith 3) in the upper-right corner of every page, including the first.
- Title: Centered on the first page below the header block — no bold, no underline, no larger font.
- Indentation: First line of each paragraph indented 0.5 inches. Works Cited entries use a hanging indent: first line flush left, continuation lines indented 0.5 inches.
- In-text citations: (Author page) format — no comma, no "p." prefix. Example: (Morrison 47), not (Morrison, p. 47) or (Morrison, 47).
- Works Cited page: Titled exactly "Works Cited" (not "Bibliography" or "References"), starting on a new page, alphabetical by author's last name.
The MLA Container System (MLA 9)
One of MLA 9's most important concepts is the container system: sources exist within larger containers. A journal article (the source) lives inside a journal (the container), which may live inside a database like JSTOR (a second container). The full MLA 9 citation for a journal article reads:
Lastname, Firstname. "Article Title." Journal Name, vol. X, no. Y, Year, pp. Z–Z. DOI or URL.
Common mistakes include omitting volume and issue numbers, forgetting to include the DOI or permalink for digitally accessed articles, and failing to add a second container when the source comes from an aggregated database.
Common Desk Rejection Reasons for MLA Manuscripts
For humanities journals that require MLA formatting, the most frequent causes of desk rejection or revision requests are:
- Wrong citation system. Submitting with APA-style author-year citations (Smith, 2022) to a journal that requires MLA author-page format. This often happens when authors draft in APA and forget to convert.
- Italics vs. quotation marks confusion. In MLA, book and film titles are italicized; article and chapter titles go in quotation marks. Many authors italicize everything or use quotation marks for long works.
- Works Cited errors. Using "Bibliography" or "References" as the heading; omitting hanging indents; incorrect alphabetical ordering; missing access dates for web sources that change over time.
- Outdated MLA edition. Submitting with MLA 7 or 8 formatting when the journal requires MLA 9 container conventions and DOI formatting.
- Missing manuscript header. Forgetting the name/instructor/course/date block. Journal submissions vary — some journals replace this with a title page — so always check the specific journal's instructions.
What CheckMyManuscript Validates for MLA
Our automated checks verify MLA in-text citation format (author-page, no comma), Works Cited page presence and title, hanging indent structure, double-spacing, manuscript header presence, and running header format. We also flag mismatches between in-text citations and Works Cited entries — a very common issue where authors cite a source in the text without adding it to Works Cited, or include Works Cited entries that are never cited.

MLA is standard in literature, languages, linguistics, rhetoric, composition, film studies, cultural studies, and related humanities disciplines. It is widely used in undergraduate coursework and humanities graduate programs.
The most frequent MLA errors are: (1) using a comma in in-text citations — (Smith, 45) instead of (Smith 45); (2) titling the reference page 'Bibliography' or 'References' instead of 'Works Cited'; (3) missing hanging indents on Works Cited entries; (4) italicizing article titles rather than putting them in quotation marks; (5) using an outdated MLA edition (MLA 7 or 8) when MLA 9 container format is required.
