Harvard Referencing: A Practical Guide With Examples
Harvard referencing is the most common author-date system in universities in the United Kingdom, Australia and many other countries. It is also the most confusing for new students, because there is no single official Harvard guide. A department's version can differ from another's in small but important ways.
This guide explains the shared logic of Harvard, shows common patterns for the sources you will cite most, and shows you how to find and follow your own institution's rules.
What Harvard style is
Harvard is a family of citation styles that share three features:
- Author-date in-text citations, giving the author's surname and the year of publication.
- A reference list at the end, in alphabetical order, with full details of each source.
- A consistent pattern for each source type.
Beyond that, details vary. Some versions use commas in citations, others do not. Some italicize book titles, and some use sentence case for article titles. Because of this variation, your first step is always to find your university's own guide. It is often called "Harvard referencing guide" on the library website, and many universities follow the widely used Cite Them Right guide.
In-text citations
Basic patterns
- Parenthetical: Reading skills improve with practice (Lee 2021).
- Narrative: Lee (2021) argues that reading skills improve with practice.
- Direct quotation with page: "Reading grows through deliberate practice" (Lee 2021, p. 14).
Some versions put a comma between the name and the year: (Lee, 2021). Use whichever your institution requires.
Several authors
| Authors | Common pattern |
|---|---|
| One | (Lee 2021) |
| Two | (Lee and Patel 2021) |
| Three or more | (Lee et al. 2021), though some versions require all names up to a limit |
| Organization | (World Health Organization 2020) |
Same author, same year
Add letters after the year: (Lee 2021a), (Lee 2021b), and use the same letters in the reference list.
No date
Use "no date" or "n.d." in place of the year, depending on your guide.
Citing a source within a source
If you read about one work in another, cite what you read: "Lee (2015, cited in Patel 2021) argues...". List only Patel in your reference list. See our guide to secondary citations.
Reference list entries
The examples below show a common pattern, using invented sources. Your university's version may differ in punctuation, capitalization or italics.
Book
Author surname, Initial. (Year) Title of book. Edition if not first. Place of publication: Publisher.
Lee, J. (2021) Reading in college: strategies that work. 2nd edn. Northfield: Northfield Press.
Many versions now omit the place of publication, so check your guide.
Journal article
Author surname, Initial. (Year) 'Title of article', Title of Journal, volume(issue), pp. page-page. Available at: DOI or URL (Accessed: date).
Lee, J. and Patel, R. (2021) 'Practice and comprehension in first-year students', Journal of College Learning, 14(2), pp. 112-129. Available at: https://doi.org/10.0000/example (Accessed: 12 March 2025).
Chapter in an edited book
Patel, R. (2019) 'Active reading in the sciences', in Gomez, M. (ed.) Study skills for higher education. Harbor: Harbor Academic, pp. 45-67.
Webpage
Author or organization (Year) Title of page. Available at: URL (Accessed: date).
World Health Organization (2020) Sleep and health for students. Available at: https://www.example.org/sleep-students (Accessed: 12 March 2025).
Many Harvard versions require an access date for online sources. Others, following newer guidance, do not. Check yours.
Newspaper article
Gomez, M. (2023) 'Why students are reading less', The City Ledger, 5 October, p. 12.
Report

The reference list
- Title: Reference list (a bibliography includes sources you read but did not cite, so use whichever your course asks for).
- Order: Alphabetical by the first author's surname.
- Layout: Many guides use a hanging indent, but some do not.
- Consistency: Use the same pattern for every entry of the same type.
If you are not sure whether to include a source you read but did not cite, check whether your assignment asks for a bibliography.
How to find your university's version
- Search your library website for "referencing" or "Harvard".
- Check your course handbook, which often links to the required guide.
- Read the assignment brief, since some tasks specify a version.
- Ask your instructor or a librarian if you cannot find one.
- Use the same guide for the whole paper. Mixing versions looks careless.
Some universities provide an online tool or a style guide with worked examples. Use those examples in preference to anything you find elsewhere.
Direct quotations and paraphrasing in Harvard
Short quotations, usually under about 30 words, sit inside quotation marks in your sentence with the author, year and page: "Reading grows through deliberate practice" (Lee 2021, p. 14). Longer quotations are indented as a block, without quotation marks, with the citation after the final punctuation. Always include the page number for a direct quotation, and use "pp." for a range.
A paraphrase needs a citation too, even though the words are yours. Many Harvard guides recommend adding a page number for a specific idea, but check your own. Use quotations sparingly, and comment on each one so the reader sees why it matters. Our wider guides on paraphrasing and avoiding plagiarism explain how to rewrite a source without copying its structure.
Special cases you will meet
| Source | What to remember |
|---|---|
| No author | Use the organization, or the title in italics, in place of the author |
| No date | Write "no date" or "n.d." according to your guide |
| Secondary source | Cite the work you read, and say "cited in" |
| Legal and government documents | Often have their own patterns in university guides |
| Lecture slides and notes | Follow your guide, and check that your instructor allows them as sources |
| Personal communication | Often cited in the text only, and left out of the reference list |
When your guide has no pattern for a source type, ask a librarian. Many university libraries run short referencing help sessions and drop-in desks.
Harvard compared with other styles
| Feature | Harvard | APA 7 | MLA 9 |
|---|---|---|---|
| In-text pattern | Author year | Author, year | Author page |
| Standard version | Many university versions | One official manual | One official handbook |
| Typical field | Business, social sciences, health, many UK courses | Psychology, education, nursing | Humanities |
| Access date for web sources | Often required | Not usually | Optional |

Common Harvard mistakes
- Using a generic guide instead of your university's version.
- Mixing punctuation styles within one list.
- Missing access dates when your guide requires them.
- Inconsistent use of et al.
- Citing page numbers inconsistently for direct quotations.
- Reference list not alphabetical, or entries missing from it.
- Putting a URL with no other details for a webpage.

A quick Harvard checklist
- Have I found and followed my university's Harvard guide?
- Does every citation have a matching reference list entry?
- Are authors, years, titles and sources correct?
- Are access dates and DOIs included where required?
- Is the list in alphabetical order and consistently formatted?
Final thoughts
Harvard is easy once you stop treating it as one fixed style. Learn the author-date logic, find the guide your institution wants, and use its examples as the final word. Then the details, from the comma after an author to the italics on a journal title, are simply a matter of copying a pattern carefully.
Frequently asked questions
Is there an official Harvard referencing style?
No. Harvard is a family of author-date styles, and many universities publish their own version. The basic idea is the same, but details such as punctuation, et al. rules and the format of web sources differ. Always follow your institution's guide.
How do I cite in the text in Harvard?
Use the author's surname and the year, such as (Lee 2021) or (Lee, 2021), depending on your university's version. Add a page number for direct quotations, such as (Lee 2021, p. 14).
How do I write a Harvard reference list?
List every source you cited, in alphabetical order by author surname, with the details needed to find it: author, year, title, publisher or journal details and, for online sources, a DOI or URL. Your university's guide sets the exact punctuation.
What does et al. mean, and when do I use it?
Et al. means and others. Many Harvard versions use it for sources with three or more authors in the text, but the threshold varies by university, so check your guide.
Is Harvard the same as APA?
Both use author-date citations, but they differ in punctuation, capitalization and other details. If your course says Harvard, do not substitute APA, since markers check the specific version.
