Harvard referencing uses the author-date system: cite sources in the text as (Author, Year) and list full details in a reference list at the end. It's widely used in the UK, Australia, and across social sciences, business, and humanities.
What Is Harvard Referencing?
Harvard is an author-date citation system, not a single fixed standard — several universities and publishers have their own Harvard-based guidelines. The core principle is consistent: author's surname and year in the text, full details in the reference list. This guide covers the most widely used conventions.
Harvard is used across business, economics, social sciences, education, and humanities — particularly in UK and Australian universities.

Frequently Asked Questions
Is there a free Harvard citation generator?▼

Is Harvard the same as APA?▼
They are both author-date systems and look very similar in text, but Harvard and APA are distinct styles with different formatting rules. APA is a specific, standardised style published by the American Psychological Association. "Harvard" is more of a family of author-date styles with variations across institutions.
How do I cite a source with no date in Harvard?▼
Use "no date" or "n.d." in place of the year. In-text: (Smith, n.d.). In the reference list: Smith, J. (n.d.) Title of Work. Publisher.
How do I cite a Harvard article with more than three authors?▼
In the in-text citation, use the first author's surname followed by "et al.": (Chen et al., 2022). In the reference list, list all authors — do not abbreviate in the full reference entry.
Does the Harvard style require page numbers in citations?▼
Page numbers are required when quoting directly: (Jones, 2023, p. 45). They are optional when paraphrasing, but many instructors encourage them for easy verification. Use "pp." for a page range: (Jones, 2023, pp. 45–47).
