Author-date referencing widely used in UK and Australian universities across sciences, engineering, and social sciences. In-text (Author, Year) with an alphabetical reference list.
Harvard referencing is an author-date citation system used predominantly in UK and Australian universities, as well as institutions across Africa, Asia, and parts of Europe. Unlike APA — which is a specific published standard maintained by the American Psychological Association — Harvard is a general approach. There is no single official Harvard manual, which means some details (punctuation, capitalisation, formatting of dates) can vary slightly between institutions. Always check your university's specific Harvard guide.
The core structure, however, is consistent: in-text citations use the author's surname and year of publication in parentheses — (Smith, 2022) — and a full reference list appears at the end of the paper, sorted alphabetically by first author's surname. For a direct quote, add the page number: (Smith, 2022, p. 45).
Harvard is used across a wide range of disciplines at UK universities, including engineering, natural sciences, social sciences, business, and some medical programmes. If your module handbook specifies "Harvard style" without further detail, this guide reflects common UK practice.
Harvard and APA are both author-date systems, and they look very similar. The key differences in UK Harvard convention are:
| Feature | Harvard (UK common) | APA 7th Edition |
|---|---|---|
| Multiple authors (in-text) | (Smith and Jones, 2022) | (Smith & Jones, 2022) — ampersand in parentheses |
| Article title format | 'Title in single quotes' | Title in plain text (no quotes) |
| Book title format | Italics | Italics (same) |
| Edition in reference | 2nd edn. | (2nd ed.) |
| Location for books | Place: Publisher | Publisher only (no location) |
| Website access | Available at: URL (Accessed: date) | URL only (no "Available at") |
| Author count (in-text) | Three+ → et al. from first citation | Three+ → et al. from first citation (same) |
Harvard in-text citations go inside parentheses at the point where you use the information — usually at the end of the relevant sentence before the full stop, or immediately after the author's name if you are attributing the idea narratively.
| Scenario | In-Text Format | Example |
|---|---|---|
| One author | (Surname, Year) | (Smith, 2022) |
| Two authors | (Surname and Surname, Year) | (Smith and Jones, 2022) |
| Three or more | (First Surname et al., Year) | (Smith et al., 2022) |
| Organisation | (Organisation, Year) | (NASA, 2023) |
| No author | (Title, Year) | (Deep Learning Review, 2023) |
| Direct quote | (Surname, Year, p. #) | (Smith, 2022, p. 45) |
| Multiple sources | (Author, Year; Author, Year) | (Chen, 2022; Patel, 2023) |
| Same author, same year | (Surname, Yeara, Yearb) | (Smith, 2022a, 2022b) |
Our STEM specialists write and reference correctly in the exact Harvard format your university requires.
For websites, include the author or organisation name, year, title of the page (italicised), availability statement (URL), and access date.
| Mistake | What to do instead |
|---|---|
| Using "&" between author names in-text | Harvard (UK) uses "and" — (Smith and Jones, 2022) |
| Not including place of publication for books | Must include: City: Publisher |
| Omitting "Accessed:" date for websites | Always include: (Accessed: 10 January 2024) |
| Capitalising every word in article titles | Sentence case only — (Smith, 2022) not (Smith, 2022) Title Case |
| Same author citations out of order | Multiple works by same author: chronological (2020 before 2022) |
| No italics on journal or book titles | Italicise journal names and book titles throughout |
| Wrong et al. threshold | Use et al. for three or more authors; list all two-author works in full |
| No page number for direct quotes | Include p. ## for every direct quotation |
Important: Harvard style varies between institutions. Some universities use "p." for page; others use "pp." for a range. Some put the year before the title in the reference list; others use different punctuation between elements. Always download your own university's Harvard referencing guide and use it as your primary reference — use this guide as a solid foundation, not the final word.
No — though they are both author-date systems and look similar. Harvard is a general approach with variations across institutions; APA is a specific published standard (currently 7th edition). If your university says "Harvard," use this guide. If it says "APA," see our APA 7th edition guide. The differences are real enough to cost marks if you mix them up.
If the article has a DOI, use the DOI — it is more stable than a URL. If there is no DOI, include the URL. In Harvard, DOIs are typically formatted as doi: 10.xxxx/xxx. For print-only articles with no online version, you do not need any URL or DOI — just the journal volume, issue, and page range.
Use the title in place of the author name, italicised for a book or report, or in 'single quotes' for an article. In-text: (Deep Learning Review, 2023). In the reference list, file it alphabetically by the first significant word of the title (ignore "The," "A," "An").
Add lowercase letters after the year: (Smith, 2022a) and (Smith, 2022b). List them in alphabetical order by title in the reference list: Smith, A. (2022a) First Book Title... / Smith, A. (2022b) Second Book Title...
Yes — many UK engineering departments specify Harvard. Some prefer IEEE. Check your module or programme handbook. When no specific style is given for a STEM report, either is generally acceptable; confirm with your tutor before submitting.
Use "no date" or "n.d." in place of the year. In-text: (Smith, no date) or (Smith, n.d.). In the reference list: Smith, A. (no date) Title. Publisher. Check your university's preference for "no date" vs "n.d."
