APA vs MLA vs Harvard: Citation Styles Explained for Students

Your teacher says "use APA" — or MLA, or Harvard — and suddenly referencing feels complicated. All three styles do the same job: show where your information came from. They just format it differently.

APA (7th edition)

Used in psychology, education, business and the social sciences. APA focuses on author and date, because recent research matters in these subjects.

• In-text: (Khan, 2023) or Khan (2023) argues that…
• Reference list: Khan, A. (2023). Climate change and agriculture in South Asia. Oxford University Press.

MLA (9th edition)

Used in English literature, languages and the humanities. MLA focuses on author and page number.

• In-text: (Khan 45)
• Works Cited: Khan, Ali. Climate Change and Agriculture in South Asia. Oxford UP, 2023.

Harvard

Popular in UK, Australian and many Pakistani universities. Very similar to APA, with small punctuation differences.

• In-text: (Khan 2023, p. 45)
• Reference list: Khan, A. (2023) Climate change and agriculture in South Asia. Oxford: Oxford University Press.

Tips that save marks

• Be consistent. Mixing styles loses more marks than small mistakes.
• Order the list alphabetically by the author's surname.
• Record sources as you go — finding a website again later is painful.
• Check the word count. Many universities don't count references; use the Word Counter on your main text only.
