What This Guide Covers

APA 7th vs 6th edition — Key changes you need to know if your institution has recently updated its style guide.

In-text citations — Narrative vs parenthetical format, direct quotes, paraphrasing, and multiple sources.

Books and book chapters — Single author, multiple authors, edited volumes, and e-books.

Journal articles with DOI — Correct DOI formatting in APA 7th and how to handle articles without DOIs.

Websites and digital sources — Including social media, online reports, and pages with no date or author.

Reference list formatting — Hanging indent, alphabetical order, italics rules, and capitalisation conventions.

APA 7th Edition — What Changed from the 6th Edition

APA 7th edition was published in October 2019. If you have used APA 6th edition before — whether through a previous course or a different institution — there are several important differences you need to be aware of. Using 6th edition rules in a 7th edition assignment will cost you marks.

Check which edition your institution uses. Many UK and Australian universities have moved to APA 7th, but some still require 6th edition. Your module handbook or referencing guide will specify which edition to use. If unclear, ask your lecturer before submitting.

APA In-Text Citations — Narrative and Parenthetical

APA in-text citations always include the author's surname and the year of publication, separated by a comma. This is the key difference from Harvard referencing, which does not use a comma between author and year. Getting this comma right matters — it is one of the most commonly penalised formatting errors.

Parenthetical Citations

A parenthetical citation places both the author and year inside parentheses at the end of the relevant sentence or clause:

Paraphrase — Parenthetical
Fixed mindset thinking limits academic achievement (Dweck, 2006).
Direct Quote — Parenthetical (with page number)
"The view you adopt for yourself profoundly affects the way you lead your life" (Dweck, 2006, p. 6).

Narrative Citations

A narrative citation integrates the author's name into the sentence as a grammatical element. The year follows the author's name in parentheses:

Paraphrase — Narrative
Dweck (2006) argues that a growth mindset is fundamental to academic resilience.
Direct Quote — Narrative (with page number)
Dweck (2006, p. 6) states that "the view you adopt for yourself profoundly affects the way you lead your life."
When to use which: Use narrative citations when the author's perspective or identity is relevant to your argument — for example, when you are discussing who argued what and why their position matters. Use parenthetical citations when the content of the claim matters more than who made it — for example, when citing a statistic or widely accepted finding.

How to Cite Journal Articles in APA 7th Edition

Journal article formatting is one of the most important citation types in APA, and also one of the most detail-sensitive. Pay close attention to capitalisation (sentence case for article titles, title case for journal names) and DOI formatting.

Journal Article with DOI

Format: Author Surname, Initial(s). (Year). Title of article in sentence case. Journal Name in Italics, Volume(Issue), Page range. https://doi.org/xxxxx

Reference List Entry
Dweck, C. S. (2008). Mindsets and math/science achievement. Carnegie Corporation of New York, 3(1), 1–8. https://doi.org/10.1016/j.cedpsych.2007.09.002
In-Text Citation
(Dweck, 2008)    or    (Dweck, 2008, p. 4)
Capitalisation rule: Article titles use sentence case — only the first word, proper nouns, and the first word after a colon are capitalised. Journal names use title case — all major words capitalised. This is the opposite of Harvard referencing, so be careful if you use both styles across different assignments.

Journal Article without DOI (with URL)

If an article does not have a DOI but is available online, include the URL instead. Unlike Harvard, APA does not require an accessed date for most online sources (unless the content is likely to change).

Reference List Entry
Sehgal, A. R. (2021). The role of medical journals in the COVID-19 pandemic. Cleveland Clinic Journal of Medicine, 88(6), 347–350. https://www.ccjm.org/content/88/6/347

Journal Article in a Database (No URL or DOI)

For print journal articles or articles accessed through a database that do not have a DOI or stable URL, omit the URL/DOI entirely.

Reference List Entry
Freud, S. (1957). Repression. In J. Strachey (Ed. & Trans.), The standard edition of the complete psychological works of Sigmund Freud (Vol. 14, pp. 141–158). Hogarth Press.

How to Cite Websites in APA 7th Edition

APA 7th has clear rules for citing web content, and the format differs in important ways from Harvard. The biggest difference: APA does not require an accessed date for most web sources (only for content that changes frequently, like wikis or social media).

Standard Website

Format: Author Surname, Initial(s). or Organisation. (Year, Month Day). Title of specific page in italics. Site Name. URL

Reference List Entry

In-Text Citation
(Centers for Disease Control and Prevention, 2023)

Website with No Author

Move the title to the author position. Italicise the title in the reference list. In the in-text citation, use the title in italics (shortened if long).

Reference List Entry

Reference List Formatting Rules

The reference list is the section at the end of your paper that provides full details of every source you cited. Getting the formatting right is just as important as getting the content of each entry right.

Page Setup

Hanging Indent

Every reference list entry uses a hanging indent: the first line of each entry is flush with the left margin, and all subsequent lines are indented by 0.5 inches (1.27 cm). In Microsoft Word, you can apply this by selecting all reference entries and using Format → Paragraph → Indentation → Special: Hanging.

Alphabetical Order

Entries are alphabetised by the first author's surname. If the same author appears multiple times, list entries in chronological order (oldest first). If the same author has multiple entries in the same year, add a, b, c after the year: (2020a), (2020b).

Common APA 7th Edition Mistakes to Avoid

Students Who Used Our APA-Formatted Assignments

★★★★★

"I kept getting penalised for APA mistakes — wrong capitalisation, wrong DOI format — even when my actual argument was solid. The assignment I received from Texvo was formatted flawlessly in APA 7th. I used it as my reference guide for the rest of the semester."

Sandra N. — Psychology, King's College London

★★★★★

"My nursing programme uses APA 7th and I had been using the 6th edition rules by mistake. The assignment I got here was correct throughout — the difference between 'doi:' and 'https://doi.org/' was something I had not even noticed. Full marks for referencing."

Emma R. — MSc Nursing, University of Sheffield

★★★★★

"I was working on a psychology dissertation and struggling to get the APA reference list right for 40+ sources. Texvo formatted the entire reference list correctly — hanging indents, alphabetical order, proper DOI links. Saved me hours of frustration."

Frequently Asked Questions

What is the difference between APA 6th and APA 7th edition?
APA 7th edition introduced several key changes: publisher location is no longer required for books; DOIs are now formatted as https://doi.org/... hyperlinks; up to 20 authors can be listed before using an ellipsis; running heads are no longer required for student papers; and font options have been broadened. Always confirm which edition your institution uses — many universities have switched to 7th but some still require 6th.
What is the difference between narrative and parenthetical in-text citations?
A parenthetical citation places both author and year in parentheses: (Smith, 2020). A narrative citation integrates the author's name into the sentence: Smith (2020) argues... Use narrative citations when the author's perspective matters to your argument. Use parenthetical citations when the information itself is the focus. For direct quotes, always include a page number in both formats.
How do I format the APA reference list?
The reference list starts on a new page titled "References" (centred, bold). Entries are alphabetical by author surname, double-spaced, with a hanging indent (first line flush left, subsequent lines indented 0.5 inches). DOIs are formatted as full hyperlinks. Volume numbers in journal entries are italicised; issue numbers are not.
How do I cite a journal article in APA 7th edition?
Format: Author Surname, Initial(s). (Year). Title of article in sentence case. Journal Name in Italics, Volume(Issue), Page range. https://doi.org/xxxxx. Article titles use sentence case; journal names use title case. The volume number is italicised; the issue number is not.
How do I cite a book in APA 7th edition?
Format: Author Surname, Initial(s). (Year). Title of book in italics and sentence case (Edition if not first). Publisher. Note: in APA 7th, you do not include the publisher's location. Example: Kahneman, D. (2011). Thinking, fast and slow. Farrar, Straus and Giroux.
How do I cite a website in APA 7th edition?
Format: Author/Organisation. (Year, Month Day). Title of webpage in italics. Website Name. URL. Unlike Harvard, APA does not require an accessed date for most web sources. For sources with no date, use n.d. in place of the year. For sources with no author, move the title to the author position.
How do I handle a source with no author in APA?
When a source has no identifiable author, move the title to the author position in the reference list. In the in-text citation, use a shortened version of the title in italics (for books) or in quotation marks (for articles/web pages), followed by the year: ("Effects of stress," 2019) or (Merriam-Webster, 2023).
What are the most common APA 7th edition mistakes?
The most common mistakes are: using title case for article titles (should be sentence case), formatting DOIs with 'doi:' prefix instead of the full URL, including publisher location (not required), missing the comma in parenthetical citations — (Smith 2020) is wrong, (Smith, 2020) is correct — not applying a hanging indent, and italicising the issue number as well as the volume number (only the volume should be italicised).
