How to Write Harvard Referencing

Harvard referencing is an author–date system: a short pointer in the text and a full entry in a reference list. Departments in business, sociology, education, geography, and many sciences use a Harvard variant. The idea is stable; the punctuation is not. Always follow the handbook your marker named, not a random website.

What Is Harvard Referencing?

Harvard is a family of author–date styles rather than a single official manual. In the text you give the author's surname and the year. At the end you give enough detail for a reader to find the source: author, year, title, publisher or journal, pages, and a DOI when there is one. Unlike numbered styles (Vancouver, some IEEE), Harvard lets a reader see who and when without flipping to the list.

Because universities publish their own Harvard guides, two "Harvard" papers can disagree about italics, commas, and whether et al. appears in the list. Consistency inside your document matters more than winning an internet argument about the One True Harvard.

Before You Start

• Download the exact guide named on the module page (Cite Them Right, a university PDF, a journal's author instructions).
• Capture full metadata as you read: all authors, year, title, journal or publisher, volume, issue, pages, DOI, and URL plus access date for unstable web pages.
• Distinguish editions, reprints, and preprints. The year in the citation is the year of the version you used.
• Decide how you will handle sources with more than two authors; your guide's et al. threshold may be three, four, or more.
• Keep a reference manager configured to your Harvard variant, then still proof the output.

Format In-Text Citations

Place surname and year in parentheses. If the author is part of the sentence, put only the year in brackets. Add page numbers for quotations and for specific claims in books.

Example: Close reading still depends on the words on the page (Richards, 1929, p. 15).

Example: As Tufte (2001) argues, chartjunk is a design failure, not a data problem.

Tip: For three or more authors, most Harvard guides use et al. in the text after the first surname. Italicize et al. only if your handbook says to.

Reference a Journal Article

Typical order: authors, year, article title, journal title in italics, volume, issue, pages, DOI.

Example: Sen, A. (1999) 'Democracy as a universal value', Journal of Democracy, 10(3), pp. 3–17.

Tip: Sentence case for article titles is common in Harvard; the journal name takes title case and italics. Do not italicize the article title.

Reference a Book or a Chapter

Books need place and publisher (or DOI for ebooks, depending on the guide). Chapters in edited volumes start with the chapter author, then the editor and book title.

Example: Kuhn, T.S. (1962) The structure of scientific revolutions. Chicago: University of Chicago Press.

Example: Crenshaw, K. (1991) 'Mapping the margins', in Bartlett, K. and Kennedy, R. (eds) Feminist legal theory. Boulder: Westview Press, pp. 357–383.

Tip: The year is the edition you actually read. A 2012 reprint of a 1962 book is still 1962 unless you are citing new editorial matter.

Cite Reports, Datasets, and Institutional Authors

When no person is named, the organization is the author. Datasets need a title, version or accession information, publisher or repository, and a persistent identifier when one exists.

Example: World Bank (2023) World development indicators. Washington, DC: World Bank.

Example: Office for National Statistics (2024) Labour market overview, UK: April 2024. Available at: https://www.ons.gov.uk (Accessed: 2 May 2024).

Tip: Spell the organization out in the first in-text citation if the acronym is not famous; many guides allow (World Health Organization, 2023) and then (WHO, 2023).

Cite Web Pages, News, and Lecture Material

Web pages need an author (or site name), year if available, title, URL, and access date. If there is no date, use n.d. Lectures and internal handouts are citable; say the module and institution.

Example: University of Manchester (2023) Harvard referencing guide. Available at: https://www.manchester.ac.uk (Accessed: 12 January 2024).

Tip: If a page is likely to change, the access date is not optional. Prefer a DOI or an archived URL when you can.

Handle Multiple Works by the Same Author

Same author, same year: add a, b, c after the year in both the citation and the list, in the order the list will sort.

Example: (Foucault, 1977a; Foucault, 1977b)

Same author, different years: cite each year; in the list, oldest first unless your guide says otherwise.

Tip: Letters are assigned from the reference list order, not from the order you first mention the works in the essay.

Build the Reference List

• One alphabetical list by surname (or organization name). Do not split books and articles into separate bibliographies unless asked.
• Hanging indent; single consistent punctuation.
• Every in-text citation has a list entry; every list entry is cited. Orphan entries look like padding.
• Secondary referencing (cited in) is a last resort: find the original. If you cannot, name both works as your handbook specifies.

Example order: Ahmed, S. ... precedes Brown, A. ... precedes UNESCO ...

Tip: Sort on the first element of the entry, ignoring The. Check that Mc and Mac follow your guide's rule, not your intuition.

Common Mistakes to Avoid

• Italicizing the article title instead of the journal title.
• Using et al. in the reference list when your handbook wants all authors (thresholds vary).
• Missing DOIs for journal articles you read online.
• Mixing Harvard in-text citations with numbered footnotes from another style.
• Omitting access dates for web sources that can change.
• Changing capitalization from entry to entry.

Pro Tips

• Configure a reference manager to your Harvard variant, then still proof punctuation.
• Store DOIs as you read; they are faster than reconstructing entries at the end.
• Cite the version you used (edition, preprint, reprint year) rather than a famous original you did not open.
• Keep one alphabetical list; do not split books and articles unless the brief says to.
• When a method is borrowed, cite the source that developed it, not only the paper that reused it.

Frequently Asked Questions

How do I cite a source with no named author?

Use the organization, agency, or website as author. If there truly is none, many Harvard guides use the title in italics or quotes in place of the author. Do not invent "Anonymous" unless the guide says to.

Do I have to include a DOI?

If the source has a DOI and you accessed it electronically, include it. It is the most stable link you can give. Some print-only handbooks make it optional; still adding it rarely hurts.

How do I cite a personal email or conversation?

Cite it in the text as a personal communication with a date. Most Harvard guides do not put personal communications in the reference list because a reader cannot retrieve them.

Should I cite software and statistical packages?

Yes, if the analysis depends on them. Cite the name, version, and developer or reference manual as your guide shows. The same applies to major datasets and code repositories.
