Harvard Referencing: How to Cite Sources With Examples

Harvard referencing is one of the most commonly requested citation styles, especially in the UK, Ireland, Australia, and many business and social science courses. Unlike APA or MLA, there is no single official Harvard manual. Each university publishes its own version, so the details can differ between institutions.

This guide explains the shared principles and gives examples. All sources in the examples are invented. Always check your own university's Harvard guide, because that is the version your marker will use.

Why Harvard Differs by University

The name "Harvard" refers to an author-date system, not to one rulebook. Universities adapt it, so you may see differences in:

• Whether "and" or "&" is used between authors
• How many authors trigger "et al."
• Whether titles are italicized or placed in quotation marks
• How online sources and access dates are shown
• Punctuation in the reference list

If your course gives you a style guide, follow it exactly, even where it differs from the examples here. Consistency matters more than any single rule.

How the System Works

Harvard has two linked parts:

1. In-text citations giving the author's surname and the year of publication
2. A reference list at the end giving the full details, in alphabetical order

Every in-text citation must appear in the reference list, and every item in the list must be cited in the text.

In-Text Citation Examples

One author: Smith (2020) argues that... or ...is widely accepted (Smith, 2020).

Two authors: Rivera and Chen (2021) suggest... or ...(Rivera and Chen, 2021).

Three or more authors: Many versions use "et al." for three or more authors: Patel et al. (2019) found... or (Patel et al., 2019).

Direct quotation: Include a page number: (Smith, 2020, p. 45). Use quotation marks for exact words.

Several sources: Order by year or alphabetically, depending on your guide: (Chen, 2018; Rivera, 2021).

Same author, same year: Add letters: (Smith, 2020a) and (Smith, 2020b).

Organization as author: (World Health Organization, 2022).

Source cited in another source: Jones (2015, cited in Smith, 2020) argues... Use this sparingly, and read the original when you can.

Reference List Examples

Reference lists are in alphabetical order by author surname. Typical Harvard formats include the following, but check your own guide for punctuation and italics.

Book

Patel, R. (2019) Research methods for health students. 3rd edn. London: Example Press.

Journal article

Rivera, M. and Chen, L. (2021) 'Sleep habits and academic performance in first-year students', Journal of Student Wellbeing, 12(3), pp. 45-62. doi:10.0000/example.

Chapter in an edited book

Lopez, A. (2020) 'Ethics in community research', in Smith, J. and Brown, K. (eds.) Handbook of applied research. London: Example Press, pp. 112-130.

Website

World Health Organization (2022) Example title of health fact sheet. Available at: https://www.example.org/fact-sheet (Accessed: 10 March 2025).

Report by an organization

National Education Agency (2021) Example report on student retention. Report no. 21-04. London: National Education Agency.

Thesis or dissertation

Chen, L. (2018) Example title of a doctoral study. PhD thesis. Example University.

Newspaper article online

Brown, K. (2023) 'Example headline about campus life', Example Times, 2 June. Available at: https://www.example.com/article (Accessed: 15 June 2023).

Many universities use an "Available at" phrase and an access date for online sources. Others have dropped access dates. This is a typical area where versions differ.

Reference List Rules to Remember

• Use alphabetical order by the first author's surname.
• If an author has several works, order by year.
• Give full details for every source cited.
• Keep punctuation and italics consistent.
• Do not number the list, unless your guide says so.
• Include a heading such as "Reference list" or "References," as your guide requires.

Reference List vs Bibliography

A reference list includes only the sources you cited in your text. A bibliography may also include sources you read but did not cite. Check which one your assignment requires. Many courses ask for a reference list.

Common Mistakes

• Mixing versions. Using one university's rules for in-text citations and another's for the reference list.
• Missing page numbers for direct quotations.
• Citation and list do not match in spelling or year.
• Unclear web sources. Missing the author, year, or URL.
• Wrong order. Not alphabetizing correctly.
• Using "et al." in the reference list when your guide asks for all authors.
• Forgetting to use quotation marks around exact words.
• Treating a reference manager's output as perfect. Check each entry.

A Simple Workflow

1. Find your university's Harvard guide and save it.
2. Record full details for every source as you read.
3. Cite in the text as you draft.
4. Build the reference list from your notes or a reference manager.
5. Cross-check every citation and entry.
6. Read the list once more for punctuation and italics.

Citing Honestly

Referencing is part of academic integrity. Whenever you use another person's ideas, data, or words, you must acknowledge them. Paraphrasing without a citation is still plagiarism. Our guide to paraphrasing without plagiarizing explains how to use sources fairly, and How to Avoid Plagiarism in Your Dissertation applies to shorter work too.

Conclusion

Harvard referencing is an author-date system with many university-specific versions. Learn the core pattern, keep detailed notes, and follow your university's guide exactly. Check that your citations and reference list match, and proofread for consistency. If you want a second pair of eyes before you submit, our citation checking support can help you spot inconsistencies in your own reference list.
