APA vs Harvard Referencing: Key Differences Explained
A clear comparison of APA and Harvard citation conventions, covering in-text format, punctuation, reference-list layout and when each style is typically required.
1Why the Confusion?
APA 7th edition (American Psychological Association) and Harvard Cite Them Right 11th edition (Pears & Shields) are both author-date systems. They look similar at a glance, but differ in punctuation, formatting rules and regional conventions. Choosing the wrong one — or mixing them — costs easy marks.

Golden rule: Always check your module handbook or unit guide. If it specifies a style, use that style exclusively — even if your previous course used a different one.
