APA vs Harvard Referencing: What’s the Difference and Which Should You Use?

If you’ve ever been told to “use APA” or “use Harvard referencing” and wondered what the actual difference is, you’re not alone. These two styles are the most commonly required at universities worldwide, and they’re more similar than different — which makes the distinctions easy to miss and easy to get wrong.

The Short Answer

APA (American Psychological Association) is a specific, formally published style guide — currently in its 7th edition. Harvard is a general author-date referencing approach with no single governing body, meaning different universities interpret “Harvard style” slightly differently.

Both use author-date in-text citations. Both list full references at the end. The differences are in the formatting details.

In-Text Citations

APA 7th Edition

• One author: (Smith, 2024)
• Two authors: (Smith & Jones, 2024)
• Three or more: (Smith et al., 2024)
• Direct quote: (Smith, 2024, p. 45)

Harvard

• One author: (Smith 2024)
• Two authors: (Smith and Jones 2024)
• Three or more: (Smith et al. 2024)
• Direct quote: (Smith 2024, p. 45)

Key difference: APA uses a comma between author and year; Harvard typically doesn’t. APA uses “&” between two authors; Harvard uses “and.”

Reference List Entries

Here’s the same book referenced in both styles:

APA

Smith, J. A. (2024). The future of academic writing. Oxford University Press.

Harvard

Smith, JA 2024, The future of academic writing, Oxford University Press, Oxford.

Key differences:

• Initials: APA uses periods after initials (J. A.); Harvard often omits them (JA)
• Year placement: APA puts the year in parentheses after the author; Harvard puts it after the author without parentheses
• Italics: Both italicise book titles
• Publisher location: Harvard often includes the city of publication; APA 7th edition dropped this requirement
• Punctuation: APA uses periods between elements; Harvard uses commas

Journal Articles

APA

Jones, B. C., & Lee, M. (2023). Citation practices among undergraduate students. Journal of Academic Writing, 15(2), 112-128. https://doi.org/10.xxxx

Harvard

Jones, BC and Lee, M 2023, ‘Citation practices among undergraduate students’, Journal of Academic Writing, vol. 15, no. 2, pp. 112-128.

Key differences:

• APA uses double quotation marks for nothing (article titles are in plain text); Harvard uses single quotes around article titles
• APA includes DOIs; Harvard traditionally doesn’t (though some universities now require it)
• Harvard spells out “vol.” and “no.” and “pp.”; APA uses the format 15(2), 112-128

Which One Should You Use?

Check your unit guide or assignment brief. This isn’t a choice — your university or department will specify which style to use. Common patterns:

• APA — Psychology, education, social sciences, nursing, business
• Harvard — Widely used across disciplines in UK and Australian universities
• MLA — English literature, humanities, arts
• Chicago — History, some humanities

If your assignment says “Harvard” but you’re unsure which version your university follows, check the library website. Most universities publish their own Harvard referencing guide with specific formatting rules.

Common Mistakes to Avoid

1. Mixing styles — using APA in-text citations with Harvard reference list formatting (or vice versa). Pick one and be consistent.
2. Incorrect et al. usage — in APA 7th edition, use et al. from the first citation for 3+ authors. Older editions had different rules.
3. Missing page numbers — both styles require page numbers for direct quotes.
4. Inconsistent capitalisation — APA uses sentence case for article/book titles in the reference list; Harvard varies by university.
5. Forgetting hanging indents — both styles use hanging indents in the reference list (first line flush left, subsequent lines indented).
