Harvard Referencing: In-Text Citations and Reference List Examples

Harvard is an author-date system: a short citation such as (Okafor, 2023) in the text, and a full entry in an alphabetical reference list at the end. There is no single official Harvard style. Universities publish their own versions, so the guide your department sets always wins. Below is a common format with ten worked examples and a table of Harvard versus APA.

What Harvard referencing is, in one minute

Harvard referencing is an author-date system. Whenever you use an idea, a fact or a quotation from a source, you put the author's surname and the year of publication in brackets in your sentence. At the end of the essay, a reference list gives the full details of every source you cited, in alphabetical order by surname.

The point is simple: the reader can see which claim came from where, and can find the source themselves.

Sleep loss measurably affects memory tasks in young adults (Okafor and Lindqvist, 2022).

Okafor and Lindqvist (2022) argue that sleep loss measurably affects memory tasks.

The first form is a parenthetical citation. The second is a narrative citation, where the author's name is part of your sentence and only the year sits in brackets.

There is no single official Harvard style

This is the point most guides skip. Harvard is a family of styles, not one rulebook. The name comes from the author-date method long used at Harvard University, but no body owns it today. Instead, universities and publishers write their own guides, and they differ in small details:

• whether the author's initials come with full stops (Okafor, A. or Okafor A.)
• whether the year is in brackets in the reference list
• whether you write and or an ampersand between authors
• when et al. replaces a list of authors (three authors, four, or more)
• whether the place of publication is required for books
• whether titles use single or double quotation marks, and where italics go

So the rule is: follow the guide your department or module handbook names. If it gives an example that differs from anything below, copy the example. Markers grade against that guide, not against a general web page. If you were told only "use Harvard", ask which version, or look for a referencing guide on your university library website.

In the UK, many universities base their guides on Cite Them Right, a widely used Harvard reference book, while others publish in-house guides. In Australia, several universities publish their own "Harvard" or "Author-Date" guides, and some of them now steer students to different styles for different faculties. Check the current version, because these guides are revised.

The common format: in-text citations

The details below follow the conventions used in most UK-style Harvard guides. They are a sensible default, not a law.

Short quotations go inside quotation marks in your sentence, followed by the citation with a page number. Longer quotations, often over about 30 words, are usually indented as a block without quotation marks. Your guide will give the exact limit. Our guide to in-text citations covers the general idea, and et al., ibid and what they mean explains the Latin terms.

The common format: reference list entries

Title the list Reference list or References. Put entries in alphabetical order by the first author's surname, with no numbering, and use a hanging indent if your guide asks for one. A bibliography is a different thing: it also lists works you read but did not cite. See bibliography versus reference list.

Below are ten examples in a common UK-style layout. Every author, title and figure is made up for illustration, so you cannot look these sources up. Italics are shown with asterisks.

1. Book

Okafor, A. (2019) Memory and sleep in young adults. 2nd edn. London: Northfield Press.

Pattern: Author surname, initial. (Year) Title. Edition (only if not the first). Place: Publisher.

2. Book with two authors

Patel, R. and Reyes, M. (2021) Writing for science students. Manchester: Riverbank Publishing.

3. Chapter in an edited book

Walsh, K. (2020) 'Sleep and learning in schools', in Lindqvist, E. (ed.) Education and health. Leeds: Hollin Academic, pp. 45-62.

4. Journal article

Okafor, A. and Lindqvist, E. (2022) 'Sleep loss and recall in first-year students', Journal of Applied Cognition, 14(3), pp. 211-229.

Pattern: Authors (Year) 'Article title', Journal title, volume(issue), pages.

5. Journal article with a DOI

Reyes, M., Patel, R. and Walsh, K. (2023) 'Reading habits in online courses', Learning Technology Review, 9(1), pp. 1-18. doi: 10.0000/example.2023.001.

The DOI above is made up and only shows the shape. Always copy the real DOI from the article page.

6. Web page with a named author

Walsh, K. (2024) How to plan a revision timetable. Available at: https://www.example.ac.uk/revision (Accessed: 1 November 2026).

Pattern: Author (Year) Title of page. Available at: URL (Accessed: date). Most Harvard guides ask for the date you viewed an online page, because pages change.

7. Web page with an organization as author

National Sleep Council (2023) Sleep and study. Available at: https://www.example.org/sleep-study (Accessed: 1 November 2026).

8. Report

Department for Education Research Unit (2022) Student wellbeing survey: main findings. Report no. 22/04. London: DERU.

9. Video

Lindqvist, E. (2021) How memory works [Video]. 14 March. Available at: https://www.example.com/video/memory (Accessed: 1 November 2026).

10. Thesis

Reyes, M. (2020) Online reading and attention in undergraduates. PhD thesis. University of Northfield.

If a work has no author, begin the entry with the title and use a shortened title in the text. If it has no date, write (n.d.).

Harvard versus APA: the differences that matter

APA 7 is also author-date, so the two look alike. They differ in details, and mixing them is one of the most common marking comments.

Because Harvard has many versions, a particular university's guide may match APA on some of these points. Treat the table as a typical pattern. Our APA 7 citation guide gives the APA side in full.

Common Harvard mistakes

• Mixing versions. Using ampersands in one place and and in another, or full stops in initials on some entries only. Pick one pattern from your guide and keep it.
• Missing page numbers on quotations. Direct quotations almost always need a page number.
• Listing sources that are not cited. That belongs in a bibliography, not a reference list.
• Citing the secondary source as if you had read the original. Use "cited in" and list only the source you actually read.
• Wrong order. Entries go by surname, A to Z, ignoring titles such as Dr.
• Copying generated output without checking it. Tools can make errors, especially with unusual sources.
• Forgetting the year or access date for web pages.

Using the Citation Generator for Harvard

The AdeptWrite Citation Generator has a Harvard mode. You fill in a form (source type, authors, title, year, publisher, URL, DOI and so on) and it produces the reference-list entry plus the in-text form. It runs in your browser. Its Harvard output follows the Cite Them Right flavour: authors listed in full up to three, "et al." for four or more, titles of articles in single quotation marks, and an "Available at" line with an access date for web pages.

That means it is a good first draft, not a final answer. Three honest limits:

1. It follows one common Harvard version. Your university may differ, for example in whether the place of publication is required, so compare the result with your guide.
2. It formats what you type. If you enter the wrong year or misspell a surname, the entry will be wrong too.
3. Unusual sources, such as legal cases, interviews or social posts, may need hand editing against your guide.

A practical routine: build each entry in the generator, paste it into your reference list, then check it against the example in your department's guide. Run the finished list through the Spell Checker to catch typos in names and titles. If you have paraphrased from sources, the Plagiarism Checker can compare your text with open encyclopedic and academic sources and list which ones it searched; it is an aid, not proof either way, and it does not search private databases or paid journals.

A short checklist before you submit

1. Have you identified which Harvard version your department uses?
2. Does every in-text citation have a matching entry in the reference list, and the reverse?
3. Are entries in alphabetical order by first author's surname?
4. Do quotations carry page numbers?
5. Are web pages dated with an access date, if your guide requires it?
6. Are initials, quotation marks, italics and punctuation consistent throughout?

If all six are yes, your referencing is in good shape.
