Harvard Referencing: The Complete 2026 Guide

Harvard referencing is an author-date system used across UK universities in disciplines ranging from social sciences to business, education, and the humanities. Unlike APA or MLA, there is no single official Harvard style — universities often publish their own variations. This guide follows the most widely accepted UK academic conventions, but always check your institution's specific handbook.

What Is Harvard Referencing?

Harvard referencing has two parts: an in-text citation that appears within your writing, and a full reference list entry at the end of your work. The in-text citation gives the author's last name and the year of publication. The reference list gives the complete source details in a standardised format. Every in-text citation must have a corresponding reference list entry, and vice versa.

Referencing Books

The standard format for a book reference is: Author Last Name, Initial(s). (Year) Title in italics. Edition if not the first. Place of publication: Publisher.

• Two authors: Smith, J. and Brown, K. (2023) Research Methods. Oxford: OUP.

• Multiple authors: (Smith and Brown, 2023) for two; (Smith et al., 2022) for three or more.

Secondary Sources

A secondary source is one you've read about in another work, without accessing the original. Use these sparingly — markers prefer you to find the primary source. When unavoidable, use: Original author (cited in Author who cited it, Year).

“When in doubt, find the original source. Citing secondary sources too often signals to markers that you haven't engaged deeply enough with the literature.”
