Harvard referencing is the most widely used citation system in UK universities. This guide covers every common source type with worked examples, the most common formatting mistakes, and how to handle tricky cases.
How Harvard referencing works
Harvard is an author-date system. Every time you use another person's ideas, findings, or words, you include a brief in-text citation in parentheses. The full details of each source appear in a reference list at the end of your document, ordered alphabetically by the first author's last name.
In-text citation: (Author, Year) or Author (Year) when the author's name is in the sentence.
Reference list: Full bibliographic details, including place of publication and publisher for books.
The in-text citation and the reference list entry must match exactly — every in-text citation needs a reference list entry, and every reference list entry must correspond to an in-text citation.
In-text citation formats
Paraphrase — using the idea but not the exact words: (Smith, 2019)
Direct quotation — using the exact words: (Smith, 2019, p. 47)
Author in the sentence — the author's name is part of the sentence: Smith (2019) argues that...
Multiple authors — two authors: (Smith and Jones, 2019)
Multiple authors — three or more authors: (Smith et al., 2019)
Multiple sources supporting the same point: (Smith, 2019; Jones, 2020; Park, 2021)
No date: (Smith, no date)
Secondary source — citing a source you have not read directly (e.g., Jones, cited in Smith, 2019): (Jones, 2001, cited in Smith, 2019, p. 45) Note: list Smith 2019 in your reference list, not Jones 2001. Use secondary sources sparingly — always try to find the original.

Common Harvard referencing mistakes
| Mistake | Problem | Fix |
|---|---|---|
| No page number for direct quotes | Harvard requires page/para numbers for quotes | Add p. or para. after year |
| Author's first name used instead of initial | Only last name + initial(s) in Harvard | Use initial: Smith, J. not Smith, John |
| Italics on article title | Only journal name is italicised | Article title in single quotation marks |
| No access date for websites | Web content changes | Add (Accessed: date) to every web reference |
| Both bibliography and reference list | Pick one as instructed | Check your module handbook |
| Source in reference list not cited in text | Reference list must match citations | Remove sources not cited, or cite them |
Using AI tools for referencing
AI tools can suggest reference formatting, but they frequently hallucinate — generating plausible-looking but entirely non-existent citations with real-sounding author names, journal titles, and volume numbers. Never use an AI-generated reference without checking it against Google Scholar, your library database, or the journal's website.
The Citation Reference Formatter generates correctly formatted Harvard references for books, journal articles, websites, theses, and other source types — without hallucination risk, since you supply the verified source details yourself.
