A Quick Guide to Harvard Referencing | Citation Examples (2023)

Referencing is an important part of academic writing. It tells your readers what sources you’ve used and how to find them.

Harvard is the most common referencing style used in UK universities. In Harvard style, the author and year are cited in-text, and full details of the source are given in a reference list.

This quick guide presents the most common rules for referencing in Harvard style.

Harvard in-text citation

A Harvard in-text citation appears in brackets beside any quotation or paraphrase of a source. It gives the last name of the author(s) and the year of publication, as well as a page number or range locating the passage referenced, if applicable:

The novel begins with the grim image of the train passengers’ faces, which are described as ‘pale yellow, the colour of the fog’ (Dostoyevsky, 2004, p. 5).

Note that ‘p.’ is used for a single page, ‘pp.’ for multiple pages (e.g. ‘pp. 1–5’).

An in-text citation usually appears immediately after the quotation or paraphrase in question. It may also appear at the end of the relevant sentence, as long as it’s clear what it refers to.

When your sentence already mentions the name of the author, it should not be repeated in the citation:

Woolf introduces the essay’s topic as ‘women and fiction’ (2000, p. 5), going on to discuss the various connotations of the phrase.

Sources with multiple authors

When you cite a source with up to three authors, cite all authors’ names. For four or more authors, list only the first name, followed by ‘et al.’:

Sources with no page numbers

Some sources, such as websites, often don’t have page numbers. If the source is a short text, you can simply leave out the page number. With longer sources, you can use an alternate locator such as a subheading or paragraph number if you need to specify where to find the quote:

(Scribbr, para. 4)

Multiple citations at the same point

When you need multiple citations to appear at the same point in your text – for example, when you refer to several sources with one phrase – you can present them in the same set of brackets, separated by semicolons. List them in order of publication date:

Several in-depth studies have investigated this phenomenon during the last decade (Singh, 2011; Davidson, 2015; Harding, 2018).

Multiple sources with the same author and date

If you cite multiple sources by the same author which were published in the same year, it’s important to distinguish between them in your citations. To do this, insert an ‘a’ after the year in the first one you reference, a ‘b’ in the second, and so on:

The results of the first study (Woodhouse, 2018a) were inconclusive, but a follow up study (Woodhouse, 2018b) achieved a clearer outcome.

Creating a Harvard reference list

A bibliography or reference list appears at the end of your text. It lists all your sources in alphabetical order by the author’s last name, giving complete information so that the reader can look them up if necessary.

The reference entry starts with the author’s last name followed by initial(s). Only the first word of the title is capitalised (as well as any proper nouns).

Sources with multiple authors in the reference list

As with in-text citations, up to three authors should be listed; when there are four or more, list only the first author followed by ‘et al.’:

Harvard referencing examples

Reference list entries vary according to source type, since different information is relevant for different sources. Formats and examples for the most commonly used source types are given below.

Books

Journal articles

Websites

Referencing sources with no author or date

Sometimes you won’t have all the information you need for a reference. This section covers what to do when a source lacks a publication date or named author.

No publication date

When a source doesn’t have a clear publication date – for example, a constantly updated reference source like Wikipedia or an obscure historical document which can’t be accurately dated – you can replace it with the words ‘no date’:

Note that when you do this with an online source, you should still include an access date, as in the example.

No author

When a source lacks a clearly identified author, there’s often an appropriate corporate source – the organisation responsible for the source – whom you can credit as author instead, as in the Google and Wikipedia examples above.

When that’s not the case, you can just replace it with the title of the source in both the in-text citation and the reference list:

Frequently asked questions about Harvard referencing

What’s the difference between Harvard and Vancouver referencing styles?

Harvard referencing uses an author–date system. Sources are cited by the author’s last name and the publication year in brackets. Each Harvard in-text citation corresponds to an entry in the alphabetised reference list at the end of the paper.

Vancouver referencing uses a numerical system. Sources are cited by a number in parentheses or superscript. Each number corresponds to a full reference at the end of the paper.

When do I need to use a Harvard in-text citation?

A Harvard in-text citation should appear in brackets every time you quote, paraphrase, or refer to information from a source.

The citation can appear immediately after the quotation or paraphrase, or at the end of the sentence. If you’re quoting, place the citation outside of the quotation marks but before any other punctuation like a comma or full stop.

How do I cite a source with multiple authors in Harvard style?

In Harvard referencing, up to three author names are included in an in-text citation or reference list entry. When there are four or more authors, include only the first, followed by ‘et al.’

	In-text citation	Reference list
1 author	(Smith, 2014)	Smith, T. (2014) …
2 authors	(Smith and Jones, 2014)	Smith, T. and Jones, F. (2014) …
3 authors	(Smith, Jones and Davies, 2014)	Smith, T., Jones, F. and Davies, S. (2014) …
4+ authors	(Smith et al., 2014)	Smith, T. et al. (2014) …

What’s the difference between a bibliography and a reference list?

Though the terms are sometimes used interchangeably, there is a difference in meaning:

• A reference list only includes sources cited in the text – every entry corresponds to an in-text citation.
• A bibliography also includes other sources which were consulted during the research but not cited.
