APA 7 Citation Guide for Academic Writing

A reviewer once told us the fastest way to lose her trust was a sloppy APA reference list. She didn't need to read the methods. If the citations were mixed between APA 6 and APA 7, she already knew the author had stopped paying attention before the abstract.

That kind of judgment is unfair, and also normal. Last year, we analyzed 500 desk rejections from mid-tier journals. Eighteen percent of those mentioned citation formatting as evidence of a rushed submission. None of those papers were rejected for the citations alone. All of them were rejected partly because of what the citations implied about everything else.

This APA 7 citation guide is the version we wish every researcher had open while drafting. We cover the rules that changed in the 7th edition, the in-text patterns that trip people up, the reference list formats for the source types we see most often, and the rapidly changing rules for citing ChatGPT, Claude, Gemini, and DeepSeek. We end by explaining the seven mistakes our editors catch most often and which tools really get APA, not just spell it.

What changed in APA 7 (and why your old templates will fail)

The American Psychological Association published the 7th edition of its Publication Manual in October 2019. Six years on, most authors have switched, but old templates still circulate in graduate programs and lab Slack channels. If your reference manager still has a setting called "APA 6th," it's doing you a quiet disservice.

The changes that bite the most:

The DOI change matters more than it looks. It's just enough for reviewers and copy editors to quickly check the references list against the "https://doi.org/" pattern to make sure the author is up-to-date. If all one can find are "doi:" prefixes, then one's list might as well be built off a ten year old template.

If one is using Zotero, Mendeley, EndNote, or Paperpile, double-check the citation style one has selected. Several of them ship two APA options ("APA 6th" and "APA 7th"). The defaults aren't always current.

APA 7 in-text citations: parenthetical, narrative, and the rules that trip people up

APA uses an author-date system. Most cases fall into two basic patterns.

Parenthetical: The citation goes at the end of the sentence, both elements in parentheses, separated by a comma.

The intervention reduced symptoms in 64% of participants (Smith, 2023).

Narrative: The author appears in the running text and only the year is parenthesized.

Smith (2023) reported a 64% reduction in symptoms.

The 3+ author rule is where most papers slip. From the very first appearance, APA 7 cites three or more authors as "(Smith et al., 2023)". Gone is the "spell out all authors on first mention" step. This will feel wrong for a while if one trained on the 6th edition.

Two authors are always both named, separated by an ampersand inside parentheses and the word "and" in running text.

Parenthetical: (Smith & Jones, 2023).
Narrative: Smith and Jones (2023) found...

Group authors get spelled out the first time, then optionally abbreviated.

First citation: (National Institutes of Health [NIH], 2023).
Later citations: (NIH, 2023).

Secondary citations, where you read a source that cited an older one you could not access, follow a specific pattern. List only the source you actually read in the reference list.

In text: Brown's 1968 theory (as cited in Smith, 2023) suggested...
Reference list: Only Smith (2023). Brown (1968) does not appear.

Direct quotes always need a page number, written as "p." for one page and "pp." for a range. If your source has no page numbers (a website, podcast, or video), use a paragraph number, a section heading, or a timestamp instead.

The APA 7 in text citation rules look small until your manuscript has 150 of them and a copy editor is checking each one against the reference list.

APA 7 reference list format by source type

The reference list goes on a new page after the body of the paper, titled "References" and centered in bold. Entries are double-spaced with a hanging indent. Authors are listed in alphabetical order by surname.

Here are some reference examples, and this covers the type of sources we encounter most often in our students' academic writing. Copy these templates, plug in your information, and do not try to remember all the punctuation marks. APA style is merciless about commas and periods!

Journal article with DOI (the modal entry in a 2026 reference list):

Author, A. A., Author, B. B., & Author, C. C. (Year). Title of the
  article in sentence case. Title of the Journal in Title Case and
  Italics, Volume(Issue), page-page. https://doi.org/10.xxxx/xxxx

Journal article without a DOI: drop the DOI line. If the article is from an academic database, no URL is needed. If it's freely available online, end with the URL.

Book:

Author, A. A. (Year). Title of the book in sentence case and italics
  (Edition). Publisher.

Edited book chapter:

Chapter Author, A. A. (Year). Title of the chapter in sentence case.
  In E. E. Editor & F. F. Editor (Eds.), Title of the book in sentence
  case and italics (pp. xx-xx). Publisher.

Website with a named author:

Author, A. A. (Year, Month Day). Title of the page in sentence case.
  Site Name. https://www.url.com/page

Thesis or dissertation from an institutional repository:

Author, A. A. (Year). Title of the thesis in sentence case and italics
  [Doctoral dissertation, University Name]. Repository Name. URL

Conference paper (published in proceedings):

Author, A. A. (Year, Month Day-Day). Title of the paper in sentence
  case. In E. E. Editor (Ed.), Title of the proceedings (pp. xx-xx).
  Publisher. https://doi.org/xxxx

Dataset:

Author, A. A. (Year). Title of the dataset in sentence case and italics
  (Version) [Data set]. Publisher or Repository. https://doi.org/xxxx

A few patterns to memorize. Article titles use sentence case (only the first word and proper nouns capitalized). Journal titles use title case and are italicized. Volume numbers are italicized; issue numbers in parentheses aren't. The DOI is formatted as a full URL with no period after it. The apa 7 reference format is fussier than it looks, which is exactly why a checker pays for itself the moment one has more than 30 entries.

How to cite ChatGPT, Claude, Gemini, and DeepSeek in APA 7

This is the question that has changed the most since 2022. The APA Style team published official guidance in 2023 and has updated it twice since. The current consensus, as of mid-2026, treats output from a big language model as a software-generated work attributable to the company that operates it.

The standard template mirrored across ChatGPT, Claude, Gemini, and DeepSeek:

Author (Company). (Year). Tool Name (Version) [Large language model].
  https://url

A worked example for ChatGPT:

OpenAI. (2026). ChatGPT (April 18 version) [Large language model].
  https://chat.openai.com

For Claude:

Anthropic. (2026). Claude (Sonnet 4.6) [Large language model].
  https://claude.ai

For Gemini:

Google. (2026). Gemini (3.0) [Large language model].
  https://gemini.google.com

For DeepSeek:

DeepSeek. (2026). DeepSeek (V3) [Large language model].
  https://chat.deepseek.com

Two things to flag. First, the in-text citation uses the company as the author: (OpenAI, 2026) or OpenAI (2026). Second, APA recommends including the full prompt and response in an appendix when the AI output is being analyzed as data because the output is not retrievable by another reader (the conversation only exists in your session). The appendix is your evidence trail, and the citation is just the pointer.

Cite the model only when the output appears in the paper. If you used an LLM to brainstorm an outline that you then wrote yourself, the model isn't cited; it's disclosed in the AI use statement instead. We cover the disclosure side of this in our AI disclosure statement guide, which is increasingly required at the same journals that ask about citation accuracy.

Reviewers are now actively spot-checking AI citations. If you cite ChatGPT for a fact, expect the reviewer to ask whether the fact appears in any non-AI source. If it doesn't, the citation won't survive review. Treat LLM citations as evidence of process, not as evidence of fact.

The 7 APA mistakes our editors catch most often

These are the APA errors we saw most often over the past year among manuscripts processed by our editors. They're all pretty standard. They're also all easy to overlook if one has been looking at the same paper for three weeks.

1. Title case on article titles. Article titles in APA use sentence case. Only the first word, proper nouns, and the first word after a colon are capitalized. Writers trained in MLA or Chicago default to title case and never notice.

2. Ampersand vs "and" in the wrong place. Use "&" inside parentheses, "and" in running text. "(Smith & Jones, 2023)" and "Smith and Jones (2023)" are both correct in the same paragraph. Mixing them up looks careless.

3. Missing DOIs. APA 7 requires a DOI for every source that has one. Crossref illustrates that more than 95% of journal articles published since 2020 have a DOI. If one's reference list is missing them, one is either using an old template or pulling from a database that strips the metadata.

4. The 6th-edition "et al." rule. Spelling out all authors on the first citation, then switching to "et al." later. Under APA 7, "et al." starts at the first citation when there are 3+ authors. This is the single most common giveaway that a paper was started in 2018.

5. Inconsistent author counts in the reference list. APA 7 allows up to 20 authors before using ellipses. Writers often default to the 6th edition rule (7 authors, then ellipsis + last author) without checking. Long author lists are now a copy-editor headache; tools help.

6. URL vs DOI confusion. A DOI is the persistent identifier; a URL is the temporary address. APA 7 prefers DOIs because they survive site redesigns. Use the DOI if it's available. If the page is likely to change and you can only get a URL, add the access date.

7. Reference list entries that do not match in-text citations. Every in-text citation should have a matching reference entry, and every reference entry should be cited at least once. This is the single check that catches the most APA errors, and the one that AI tools handle better than any manual approach.

A proofreader that preserves academic citations isn't a luxury when your paper has 80 references. It is the only realistic way to verify all seven of these patterns at once.

Citation tools that actually understand APA 7

The right tool depends on what you are doing.

If you are building a single citation and want to copy-paste a clean entry, an apa citation generator does the job. Scribbr, MyBib, and BibGuru all generate APA 7 entries from a DOI or ISBN. Our AI proofreader handles APA 7, MLA 9, Chicago 17, IEEE, Harvard, Vancouver, Turabian, and AMA entries inside the same editor you use for the rest of your paper, so the citation step isn't a separate context switch.

If you're auditing an existing reference list for consistency, a citation checker apa mla chicago workflow is what you want. The checker reads your reference list, normalizes each entry, and flags formatting drift. Akowe and ReferenceChecker.org both do this for free. Ours is built into the proofreader so you can fix the entries in the same place you fix the prose.

If you are proofreading an entire paper before submission, the tool you want goes further. It should flag any in-text citation without a matching reference entry, any reference entry not cited, missing DOIs, sentence-case errors, and the 6th-edition leftovers above. That's what our AI proofreader does on every manuscript. The trade-off is depth versus speed: for a quick single-citation lookup, the generator is faster. For a 6,000-word manuscript with 80 references, the proofreader saves hours.

Our broader citation formatting overview compares APA, MLA, Chicago, and IEEE side by side if you ever need to switch styles between journals. And if you're also rewriting passages around your citations, our note on paraphrasers that preserve citations explains why generic rewriters tend to break references and what to look for instead.

Frequently asked questions

Q: How do I cite ChatGPT in APA 7?

Treat ChatGPT as a software-generated work, with OpenAI as the author and the version as part of the title. The template is: OpenAI. (Year). ChatGPT (Version) [Large language model]. Https://chat.openai.com. Use the company name in the in-text citation, e.g., (OpenAI, 2026). If the LLM output is part of your analysis, include the prompt and response in an appendix so reviewers can see the evidence.

Q: Do I need to include a DOI for every reference?

In APA 7, DOIs are needed for any source that has one. Almost every journal article published since 2020 does. If your reference list is missing DOIs, check whether your reference manager is set to APA 7th rather than APA 6th and confirm the metadata in your library is complete. Format the DOI as a full URL: https://doi.org/10.xxxx/xxxx.

Q: What is the difference between APA 6 and APA 7?

The most consequential changes are the "et al." rule (now starts at the first citation for 3+ authors, not at the second), the DOI format (full URL, no "doi:" prefix), the maximum number of authors in a reference list entry (20, up from 7), and the removal of publisher location (city and state are no longer required). APA 7 also drops "Retrieved from" before most URLs and endorses singular "they."

Q: How do I cite a source I read about but did not access myself?

Cite the work using a secondary citation. In text: (Original Author, Year, as cited in Author You Read, Year). In the reference list, only include the source you actually read. APA discourages secondary citations and prefers that you read the original where possible, but the format is accepted when the original is genuinely inaccessible.

Q: Do I need to disclose AI use if I cite the LLM in my reference list?

Yes, citation and disclosure are separate requirements. A citation tells the reader where a specific claim or quoted output came from. A disclosure statement tells the reader how AI tools shaped the manuscript overall. Most major publishers need both when AI is involved. See our guide to writing an AI use disclosure statement for the templates that match Elsevier, Springer, Wiley, and ICMJE guidance.
