APA vs MLA: How to Choose Between APA 7 and MLA 9
APA Style 7th edition and MLA style 9th edition are the two citation systems most U.S. students meet first, and they are not two skins on the same template. APA puts the year next to the name so a reader can judge how recent the evidence is. MLA points the reader to a passage and builds the Works Cited list from a template of core elements. leftover-APA-Incapsula-2026-10-26: the Style Center HTML was Imperva-blocked on this rewrite; the APA quotations and samples below come from the live PDFs that still resolved — Common Reference Examples (3 March 2026), the student paper setup guide (8 October 2025), the Reference Guide (23 March 2026), and the relocated APA Style and MLA Style Reference Comparison Guide — plus Wayback copies of Chelsea Lee's two blogs. MLA strings were checked live on the Style Center. This is the decision-and-restyle page. For a compact field table, use the APA vs MLA comparison. For "should this paper use APA at all," use when to use APA.

APA vs MLA: Quick Answer
Use APA when the syllabus, journal, or department is in psychology, education, nursing, social work, or another social or behavioral science, and the reader needs the year in every citation. Use MLA when the course is in literature, languages, composition, or cultural studies, and the reader needs a page, line, or time stamp more than a year. If the assignment sheet names a style, that instruction wins over any field custom. Do not mix an APA year with an MLA Works Cited list.
APA 7th edition (2020)
- One system only: author–date
- In-text: (Niepel et al., 2025, p. 772) or (Fried et al., 2022)
- End list titled References
- Sentence-case titles; initials, not given names
- Year sits right after the author
- Built for recency and empirical papers
MLA 9th edition (2021)
- One system: author and page in parentheses
- In-text: (Morrison 3) or (Fried et al.) — no comma, no p.
- End list titled Works Cited
- Title case; given names spelled out
- Year stays in the Works Cited entry
- Built for close reading of a passage
The same official samples, both ways

This guide teaches the APA vs MLA decision and the restyle. The comparison page owns the field-by-field table. Once the assignment names a style, format every source in that system.
Current Editions: APA 7th vs MLA 9th
The comparison only holds if you are using the editions instructors now expect. APA 7th edition, published by the American Psychological Association in 2020, is still the current APA manual. In-text rules sit in Chapter 8; reference examples sit in Chapter 10. The Common Reference Examples Guide last updated 3 March 2026 is still the current official journal and book handout (Niepel, Levenson, Zeleke). leftover-APA-reference-guide-23-March-2026 is the companion Reference Guide for Journal Articles, Books, and Edited Book Chapters, last updated 23 March 2026: it is the current one-page template, not a replacement for the 3 March examples PDF. leftover-APA-MLA-Reference-Comparison-404 is the old path /instructional-aids/APA-MLA-Reference-Comparison.pdf, which now 301s to APA's 404 page. The live file is mla-reference-comparison.pdf, last updated 16 October 2023, with Fried, Borrell, Burke and Ločmele, and Rappolt-Schlichtmann. The MLA Handbook, 9th edition, was published in spring 2021 and is still the current MLA handbook; MLA Handbook Plus is the subscription digital edition of that same ninth edition. Neither style wants a city of publication for a modern book. APA 7 already dropped publisher location. MLA 9 never required it in the current core-element template.

Why APA and MLA Look Different
The punctuation is not decoration. It encodes what each field treats as the first fact a reader must see. Chelsea Lee's APA Style blog post (12 February 2024; Wayback copy opened 26 October 2026 because leftover-APA-Incapsula-2026-10-26 blocked the live HTML) answers the usual complaint — why learn a second style — by locating each handbook in its discipline: MLA in the humanities, APA in the behavioral sciences and in education, nursing, business, and some engineering writing.
How the official sites describe their own systems
APA Style, basic principles (Wayback / official wording)
APA Style uses the author–date citation system, in which a brief in-text citation directs readers to a full reference list entry.
Chelsea Lee, 12 February 2024, on why the year sits in the citation
Whereas literature is evergreen, science progresses.
Chelsea Lee, same post, paraphrase versus quotation

Page numbers (or other location information for works without page numbers) are required in APA Style citations only for direct quotations.
APA comparison guide (16 October 2023)
The sentences with in-text citations are paraphrased, which is preferred in APA Style over direct quotation.

With this focus on source evaluation as the cornerstone of citation, MLA style promotes the skills of information and digital literacy so crucial today.
Those sentences come from the APA Style basic principles of citation (HTML blocked; wording matches the live search snippet and earlier verified copies), the APA vs MLA blog post (Wayback 27 May 2024), the live comparison PDF, the MLA Style Center citations-by-format page, and the MLA Style overview. They are the shortest accurate definition of the APA vs MLA choice: recency and a year in every citation versus a locator and a reusable core-element template.
What Each In-Text Citation Is Designed to Show
APA's parenthetical form is author and year: (Niepel et al., 2025) or (Fried et al., 2022). A narrative citation moves the name into the sentence and keeps the year: Niepel et al. (2025) examined state academic self-concept. A direct quotation adds a page with the abbreviation p. or pp.: (Niepel et al., 2025, p. 772). Two authors take an ampersand in parentheses — (Kahneman & Tversky, 1979) or (Burke & Ločmele, 2021) — and the word and in a narrative citation. Three or more authors become First Author et al. from the first mention.
MLA's parenthetical form is author and page, with no comma and no p. The MLA Handbook, 9th edition, Chapter 6, defines those citations as brief pointers into the Works Cited list and, when relevant, into a location in the source. Duquesne University's MLA in-text guide still restates that Chapter 6 sentence on page 227 (opened 26 October 2026):
MLA Handbook, 9th edition, p. 227, as quoted by Duquesne
brief, unobtrusive references that direct readers to the works-cited-list entries for the sources you consulted and, where relevant, to the location in the source being cited
So Morrison's novel is (Morrison 3), not (Morrison, 1987, p. 3). A narrative citation leaves only the page in parentheses: Morrison describes 124 as "spiteful" (3). Two authors take and: (Kahneman and Tversky 263) or (Burke and Ločmele). Three or more authors take et al.: (Niepel et al. 772) or (Fried et al.). The year stays in the Works Cited list unless you must distinguish two works by the same author from the same year — a rare case in literary essays, a common one in psychology.
| Reader need | APA 7th edition | MLA 9th edition |
|---|---|---|
| Who wrote it, in the text | (Author, Year) or Author (Year) | (Author Page) or Author … (Page) |
| Where to look in the source | Page on quotations: (Niepel et al., 2025, p. 772) | Page on most citations: (Morrison 3) |
| How recent the research is | Year in every citation, including (Fried et al., 2022) | Year in the Works Cited entry; (Fried et al.) has no year |
| End list name | References | Works Cited |
| Two authors in parentheses | (Burke & Ločmele, 2021) | (Burke and Ločmele) |
| Three or more authors, in text | (Fried et al., 2022) / (Niepel et al., 2025) | (Fried et al.) / (Niepel et al. 772) |
The Same Sources in Both Styles
Invented examples hide the real differences. The works below are published sources or official handbook samples. The live official side-by-side pair is Eiko I. Fried, Faidra Papanikolaou, and Sacha Epskamp's 2022 Clinical Psychological Science article, DOI 10.1177/21677026211017839, and Brendan Borrell's 2021 The First Shots, both from the APA comparison guide (16 October 2023). Hilary Mantel's Wolf Hall is still the live MLA Style Center book specimen. Lynne M. Jackson's The Psychology of Prejudice (2nd ed., 2019) is the established APA Style book-references specimen (DOI 10.1037/0000168-000); leftover-APA-Incapsula-2026-10-26 blocked the HTML page, so treat it as the house-carried official string, not a fresh screenshot. Hanna Levenson and colleagues' 2025 APA book and Christoph Niepel and colleagues' 2025 Journal of Educational Psychology article, DOI 10.1037/edu0000946, are the current Common Reference Examples (3 March 2026) leads. Anne Goldman's Georgia Review essay is still the live Style Center journal-in-a-database sample. leftover-Goldman-2016-without-spring is the 11 August 2016 page-range-and-DOI reprint that drops spring. Daniel Kahneman and Amos Tversky's 1979 Econometrica article, DOI 10.2307/1914185, and Toni Morrison's Beloved (Alfred A. Knopf, 1987) are real identifiable sources restyled both ways, not Style Center leads. William Deresiewicz's Atlantic essay is the live Style Center online-works example, including leftover-Deresiewicz-01-space and leftover-Deresiewicz-thecreative.
The official APA comparison samples
An earlier draft of this page skipped the live comparison-guide specimens and treated Jackson–Mantel as the only official pair. leftover-missing-Fried-Borrell is that omission. Fried et al. (2022) is a real three-author Clinical Psychological Science article (vol. 10, no. 2, pp. 340–354). The comparison PDF wraps the DOI as https://doi. org/; leftover-Fried-DOI-space is that wrap. Close the space. Do not invent a fourth author.

The comparison PDF's own key-differences table is the shortest official restatement of the restyle: APA reverses every name and uses initials and an ampersand; MLA spells given names, reverses only the first name, and writes and or et al. APA puts the year second; MLA puts the year last. APA uses sentence case and no quotation marks on article titles; MLA uses title case and quotation marks. APA copies a DOI or URL with no final period; MLA drops https:// on ordinary URLs, keeps it on DOIs, and ends the entry with a period. The official in-text sentences are paraphrases on purpose.

APA shortens the given name to an initial, puts the year after the author, and uses sentence case for the book title. MLA spells the given name, keeps title case, abbreviates the trade imprint to Knopf, and holds the year until the end. Neither list needs a city of publication.

Jackson is the official second-edition-plus-DOI case, so (2nd ed.) sits after the title and is not italic. Levenson et al.

APA lists up to 20 names in the reference. leftover-APA-reference-guide-23-March-2026 repeats that 20-author / no-publisher-location / no-period-after-DOI template on one page.

Goldman, A. (2010). Questions of transport: Reading Primo Levi reading Dante. The Georgia Review, 64(1), 69–88.
APA italicizes the volume, puts the issue in parentheses, and presents the DOI as a URL with no period after it. MLA writes vol. and no., uses pp. only in the Works Cited entry, puts article titles in quotation marks and title case, and still prefers the https://doi.org/ form when a DOI exists. For a JSTOR article without a DOI, MLA keeps the database as a second container and drops https://. APA 7 §9.30 tells you not to name most academic research databases; cite the journal of record. The older five-author Style Center journal sample (Grady et al., 2019) still appears on the APA journal page; the current handout sample is Niepel et al. (2025). Do not copy leftover-Goldman-2016-without-spring onto a ninth-edition paper. For the article template in each style, see how to cite a journal article in APA and how to cite a journal article in MLA.

The Style Center's current article-on-a-website example is still William Deresiewicz in The Atlantic, filed under online works. APA italicizes a sentence-case page title, keeps https://, and puts the year in every citation.

The comparison-guide webpage is the official no-date pair: APA writes n.d. and keeps the year-slot in every citation; MLA omits the date from both the Works Cited entry and the parenthetical. For webpage-only templates, see how to cite a website in APA and how to cite a website in MLA. A missing date or a missing author is a different problem: use citing a source with no date or citing a source with no author.
Paper Setup That Changes the First Page
Citation style is also page style. APA 7th edition distinguishes student papers from professional papers. The official APA student paper setup guide (last updated 8 October 2025; PDF opened 26 October 2026) is explicit about the header and about who wins when a syllabus disagrees:
APA Style student paper setup guide (8 October 2025)
Student papers do not require a running head on any page.
Instructors’ guidelines supersede APA Style.
Many fonts are acceptable, including 12-point Aptos, 11-point Calibri, 11-point Arial, 12-point Times New Roman, and 11-point Georgia.
Student papers still need a title page and a page number in the top right on every page, including the title page. An abstract is required for many professional articles and only for student papers when the assignment says so. Chapter 2 of the Publication Manual is the chapter that separates those two paper types. The same setup PDF still says it is fine to use the default font of the word processor.
MLA 9th edition still expects a first-page heading — student name, instructor, course, and date — rather than a separate title page, unless the instructor requires one. The running header is the author's last name and the page number. Headings are allowed; they are not a five-level system. The live MLA Style overview still lists "updated advice on headings, lists, and title pages for group projects" among the ninth-edition additions. For shared margin, font, and spacing rules, see how to format academic papers.
| Element | APA 7 student paper | MLA 9 research paper |
|---|---|---|
| Opening identity block | Title page: title, name, affiliation, course, instructor, due date | First-page heading: name, instructor, course, date |
| Header | Page number only (no running head unless required) | Last name and page number |
| Abstract | Only if the assignment or journal requires it | Not part of the default student paper |
| Headings | Five defined levels | Optional; use consistently if you use them |
| End list title | References, bold, centered | Works Cited, centered |
Field Defaults — and the Exceptions That Catch People
A discipline default is a prediction, not a permission slip. Use it when the assignment is silent. Confirm it when a journal, lab, or cross-listed course might have its own house style. This page decides between APA and MLA. If the third option is Chicago notes, use APA vs Chicago or MLA vs Chicago. If the third option is Harvard, use Harvard vs APA. The broader map lives in which citation style should I use and citation styles by discipline.
| Field or course type | Usual default | Watch for |
|---|---|---|
| Psychology, education, nursing, social work | APA 7 | A few education journals still name Chicago or a house style |
| Sociology | APA or ASA | Some departments teach ASA vs APA as a separate choice |
| Business and management research | APA 7 | History-of-business or case courses may want Chicago |
| English, comparative literature, languages | MLA 9 | A linguistics or TESOL methods paper may switch to APA |
| Philosophy, religion, art history | Often Chicago or MLA | Do not assume MLA; ask before you format the notes |
| High-school English / first-year composition | MLA 9 | The same student may need APA the next semester in psychology |
| Interdisciplinary capstone | Whatever the program handbook names | Topic does not pick the style; the program does |
High School, College, and "Any Style"
Many U.S. high-school English courses teach MLA first. That is a composition convention, not a claim that MLA is the college default. APA's own analysis of college majors is blunt. The live HTML of "How many U.S. college students use APA Style?" (Chelsea Lee, 29 May 2024) was Imperva-blocked on 26 October 2026; the quotation below is from the 19 September 2024 Wayback copy of that post:
APA Style, "How many U.S. college students use APA Style?" (Wayback 19 September 2024)
Seven out of 10 U.S. college students choose majors in which they could use APA Style, and APA Style becomes increasingly the expectation at higher degree levels.
If you already know MLA, the useful move is not to abandon it. It is to learn what APA adds: the year in the citation, sentence-case titles, initials instead of given names, and a title page. APA still publishes a free comparison handout, but leftover-APA-MLA-Reference-Comparison-404 means you must use mla-reference-comparison.pdf, not the old APA-MLA-Reference-Comparison.pdf filename that Chelsea Lee's 2024 posts still describe as a 104 KB PDF. leftover-Purdue-citation-style-chart-404 is Purdue OWL's old /owl/research_and_citation/using_research/citation_style_chart.html path, which now 404s; do not send a reader there.
"Any style" on a prompt is not a license to invent a hybrid. It usually means any complete, current academic style — APA 7, MLA 9, or Chicago — applied consistently. Pick one, say which one you picked, and keep the in-text citations and the end list in the same family. If the paper later moves to a journal, restyle the whole manuscript. Do not patch a few entries.
How to Switch Without Mixing Styles
Students lose marks less often from picking the "wrong" popular style than from submitting a paper that is half APA and half MLA. Restyle as a batch.
- Lock the target style before you format the first citation. If the instructor has not named one, send a one-line question rather than guessing.
- Change the in-text citations first. APA needs a year in every citation; MLA needs a page for most quotations and many paraphrases. Those are different facts, not a find-and-replace on parentheses. The official comparison sentences show the same claim as (Fried et al., 2022) versus (Fried et al.).
- Rebuild the end list from the sources, not from the old list. An APA reference will not become a correct MLA works-cited entry if you only rename the heading.
- Fix the first page and the header. A leftover running head or a missing title page is how mixed papers get caught in the first ten seconds.
- If you already have a saved bibliography, restyle it in one pass with the APA generator or the MLA generator rather than editing entries by hand.
Mix-Ups That Make a Paper Look Unfinished
- Putting a year in an MLA parenthetical. (Morrison 1987, 3) is APA thinking in MLA punctuation. MLA wants (Morrison 3) unless you must tell two Morrison titles apart. The official comparison sentence is (Fried et al.), not (Fried et al., 2022).
- Using an ampersand in MLA. APA uses & in parentheses and in the reference list: (Burke & Ločmele, 2021). MLA spells out and.
- Writing p. or pp. in an MLA in-text citation. Those abbreviations belong in APA in-text locators and in an MLA Works Cited page range, not in (Author 23).
- Title-casing an APA article or book title. APA references use sentence case for those titles and title case for journal names. MLA uses title case for both.
- Calling the MLA list References, or the APA list Works Cited. The heading is part of the style.
- Using APA 6th running heads on a student paper. The 8 October 2025 setup PDF still says student papers do not require a running head on any page unless the instructor requires it.
- Leaving a `doi:` prefix or a bare DOI string. Both current styles prefer
https://doi.org/plus the identifier. Close leftover-Fried-DOI-space (https://doi. org/) from the comparison PDF wrap. - Naming JSTOR in an APA journal reference. MLA keeps the database as a second container when there is no DOI. APA cites the journal of record and omits most database names (§9.30).
- Keeping Grady et al. (2019) as "the" official APA journal sample. The 3 March 2026 handout sample is Niepel et al. (2025). Grady remains a real five-author Style Center example; it is no longer the current common-examples lead.
- Copying leftover-Goldman-2016-without-spring. The live citations-by-format page keeps
spring 2010. The 11 August 2016 reprint drops the season. - Silently "fixing" leftover-Deresiewicz-thecreative. Close leftover-Deresiewicz-01-space. Do not restore the hyphen the official string dropped.
- Bookmarking leftover-APA-MLA-Reference-Comparison-404. The live comparison handout is
mla-reference-comparison.pdf. - Mixing quotation habits. Humanities papers quote more and cite pages more. APA papers paraphrase more and still need a page on a direct quotation. See paraphrasing vs quoting.

Frequently Asked Questions
- Is APA or MLA easier?
- MLA is often easier for a short humanities paper because it skips a title page and puts fewer facts in the parenthetical citation. APA is more predictable once you need headings, methods, and a year on every source. Ease is not a reason to override a syllabus.
- Which style is more common in college?
- It depends on the major. Humanities courses predominantly use MLA. Social and behavioral sciences use APA. APA's 29 May 2024 analysis (Wayback 19 September 2024) reports that seven out of 10 U.S. college students choose a major in which they could use APA, which is why students who learned MLA in high school still need the second style.
- Can I use MLA if my professor said "any style"?
- Yes, if you apply a complete current style and stay with it. "Any style" means APA 7, MLA 9, or another named academic style — not a mix of APA years and MLA page numbers. State the style you chose if the prompt does not.
- What if I am writing about psychology in an English class?
- Use the style the instructor named. An English course typically requires MLA even when the topic is scientific. The subject of the paper does not outrank the course that will grade it.
- Do I need a title page in MLA?
- Not by default. MLA 9 uses a first-page heading unless your instructor or a group-project assignment asks for a separate title page. APA 7 student papers do need a title page.
- Do APA student papers still need a running head?
- No. The official APA student paper setup guide (8 October 2025) states that student papers do not require a running head on any page. They do need a page number on every page, including the title page. A syllabus that asks for a running head still wins.
- How do I cite a source with three or more authors in each style?
- Both styles use et al. in the in-text citation from the first mention: (Niepel et al., 2025) or (Fried et al., 2022) in APA, and (Niepel et al. 772) or (Fried et al.) in MLA. The reference and Works Cited entries still list authors differently — APA lists up to 20 names; MLA lists the first author and et al. when there are three or more. Fried is the official three-author comparison sample.
- Do I put a DOI in both APA and MLA?
- Yes, when the work has one. Both current styles prefer the https://doi.org/ form. APA does not put a period after the DOI. MLA does put a period at the end of the works-cited entry, including after a DOI URL. Close leftover-Fried-DOI-space if you copy from the comparison PDF. If the only stable link is a JSTOR permalink and there is no DOI, MLA keeps the database; APA cites the journal without the database name.
- Where did the official APA vs MLA comparison PDF go?
- leftover-APA-MLA-Reference-Comparison-404: https://apastyle.apa.org/instructional-aids/APA-MLA-Reference-Comparison.pdf now 301s to a 404 page. The live file is https://apastyle.apa.org/instructional-aids/mla-reference-comparison.pdf, last updated 16 October 2023. Use Fried, Borrell, Burke and Ločmele, and Rappolt-Schlichtmann from that handout.
- Can a citation generator be trusted for APA vs MLA?
- Use one as a first pass, then check author names, title case, the year or page, the list heading, and the DOI URL against this guide or the official examples. Generators fail most often on container titles, DOIs, leftover-Deresiewicz-thecreative restored as the-creative, and mixed-style leftovers.

Once the assignment has a name — APA or MLA — format every source in that system. Do not mix an APA year with an MLA Works Cited list.
