Harvard Referencing: The Complete Guide with Examples (2026)
Harvard referencing: in-text citations, reference lists and examples for common source types, including books, journals, websites and reports.
Harvard referencing is a citation system used at many universities in the UK, Australia and Scandinavia. It is an author-date style: you cite sources in the body of your text using the author's surname and the year of publication, then give full details in a reference list at the end.
This guide covers common source types: books, journal articles, websites, reports, theses, newspaper articles, and a few more. Use it as a reference alongside the Harvard reference generator, which formats references automatically from a URL or DOI.
The examples follow Cite Them Right, 13th edition (2025), the Harvard version that many UK university guides use. A university that still uses the 12th edition or its own variant can differ in details such as place of publication, so check your own guide. Some authors, titles and web addresses in the examples are invented, to show the format.
How Harvard referencing works
Every Harvard citation has two parts that must match each other:
- In-text citation: a short marker in the body of your text that points the reader to the source: (Smith, 2021) or Smith (2021).
- Reference list entry: the full bibliographic details at the end of your work, listed alphabetically by the first author's surname.
Every source you cite in your text must appear in the reference list, and every entry in your reference list must be cited somewhere in your text. If you read something for background but did not cite it, it goes in a bibliography (if your institution requires one), not the reference list.
In-text citations
The in-text citation goes either in parentheses at the end of the relevant sentence, or woven into the sentence itself with the author's name outside the brackets.
One author
Parenthetical
Narrative (author in sentence)
Two authors
In-text
Cite Them Right writes "and" both inside the brackets and in running text. Some university variants use an ampersand (&) inside the brackets.
Four or more authors
In-text (4+ authors)
Cite Them Right uses "et al." from four authors onwards in the in-text citation; with three, name all of them: (Fossum, Skantz and Katzeff, 1997). List all authors in full in the reference list.
No date
In-text: no date
Write "no date" when a publication date cannot be established, as Cite Them Right does. Some university guides shorten it to "n.d.", and Swedish ones use "u.å." (utan år).
Direct quotation
In-text: direct quote with page number
Cite Them Right gives the page after a comma with "p." (or "pp." for a range), as APA does. Some older Harvard variants write a colon instead: (Smith, 2021: 42). For a paraphrase, page numbers are optional but recommended.
Multiple sources in one citation
In-text: multiple sources
List multiple sources inside one pair of parentheses, separated by semicolons, in alphabetical or chronological order depending on your university's preference.
Same author, same year
In-text: distinguishing two works from the same year
Add a lowercase letter after the year. Use the same letter in the reference list entry.
The reference list
The reference list starts on a new page at the end of your work, headed "References" (or "Reference list"). Entries are listed alphabetically by the first author's surname, then by year for multiple works by the same author. Do not number entries or use bullet points.
Books
Book: standard format
Reference list
Cite Them Right 13th edition no longer includes the place of publication for books. The 12th edition and many university guides still write it before the publisher (Place of publication: Publisher), so add it if your university asks for it.
Example
Book with two authors
Reference list
Book with three or more authors
Reference list
Edited book
Reference list
Chapter in an edited book
Reference list
Note: the chapter title goes in single quotation marks; the book title is in italics.
Later edition
Reference list
Ebook with DOI
Reference list
Journal articles
Journal article: standard format
Reference list
Example
No DOI, freely available online
Reference list
Journal article with many authors
Cite Them Right uses "et al." in the in-text citation from four authors. In the reference list, Cite Them Right guides at some universities allow the first author followed by "et al." from four authors, while others ask for every author. Follow your university's guide.
Websites
Website: standard format
Reference list
Named author
Organisation as author
Cite Them Right asks for an accessed date for web pages and other online sources you find by URL. It is not needed when you cite a source with a DOI.
Website with no date
Reference list
Reports and government documents
Reference list: institutional report
Reference list: government document
Newspaper and magazine articles
Newspaper article in print
Reference list
Example
Newspaper article online
Reference list
Theses and dissertations
Reference list
Online thesis
YouTube and online videos
Reference list
The channel is the author. The upload date replaces the standard year-only format. See the full guide on citing YouTube videos.
Social media
Reference list: social media post (pattern)
Check your university's Cite Them Right guide for the exact form, since guides differ on details such as where the platform name goes.
Lecture notes and course materials
Reference list
Secondary citations
A secondary citation is when you cite a source you read about in another work, rather than reading the original yourself. Avoid this wherever possible: find and read the original. If unavoidable:
In-text: secondary citation
Reference list: only the source you actually read
Quick-reference: in-text citation formats
| Situation | In-text format |
|---|---|
| One author | (Smith, 2021) |
| Two authors | (Smith and Jones, 2021) |
| Four or more authors | (Smith et al., 2021) |
| No date | (Smith, no date) |
| Direct quote with page | (Smith, 2021, p. 42) |
| Author named in sentence | Smith (2021) argues that … |
| Multiple sources | (Garcia, 2019; Lee, 2021) |
| Same author, same year | (Smith, 2020a) and (Smith, 2020b) |
| Organisation as author | (World Health Organization, 2024) |
| Secondary citation | (Jones, 2010, cited in Smith, 2020) |
Common mistakes in Harvard referencing
- Inconsistent punctuation. Harvard has no single standard; your university's guide is the rule. Pick one and apply it consistently throughout your work.
- Missing the accessed date for websites. Cite Them Right asks for an accessed date on web sources found by URL. It is not needed when you cite with a DOI.
- Using "et al." where your university wants every author. Cite Them Right guides at some universities allow the first author followed by "et al." in the reference list from four authors, while others ask for all authors. Check which applies.
- Mixing editions. Cite Them Right 13th edition dropped the place of publication for books, while the 12th edition and many university guides still include it. Follow the edition your university names.
- Treating a paraphrase as if it needs no citation. Any idea that is not your own needs a citation, whether you quote it directly or restate it in your own words.
- Mixing up the reference list and bibliography. A reference list contains only cited sources; a bibliography may include background reading. Your assignment brief will specify which is required.
- Putting article titles in italics. In Harvard, article titles go in single quotation marks. Italics are for the title of a whole work, such as a journal, book, report or web page.
The fastest way to avoid all of these is to let a tool handle the formatting. Paste any URL, DOI or ISBN into the Harvard reference generator and CitApp fetches the metadata and produces a correctly formatted entry in seconds.

Frequently asked questions
What is Harvard referencing?
Harvard referencing is an author-date citation system widely used at British, Australian, and Scandinavian universities. Rather than footnotes or numbered references, you cite sources inline in your text using the author's surname and the year of publication, then list full details in a reference list at the end of your work.
Is there an official Harvard referencing style guide?
No. Unlike APA or MLA, Harvard is not owned or standardised by any single organisation. Each university publishes its own variant, which means small details (punctuation, how to handle "no date", whether to include the place of publication) vary between institutions. Always check your university's specific guide.
What is the difference between a bibliography and a reference list?
A reference list contains only the sources you actually cited in your text. A bibliography may also include background reading that informed your work but was not directly cited. Most university assignments ask for a reference list, not a bibliography, so check your assignment brief.
How do I cite a source with no author in Harvard?
Use the organisation or institution responsible for the work in place of the author. If there is genuinely no author or organisation, move the title of the work into the author position. In the in-text citation, Cite Them Right uses the title in italics in place of the author, followed by the year.
Do I need a DOI when Harvard referencing a journal article?
Most modern university Harvard guides ask for a DOI (Digital Object Identifier) when one is available, written as a full URL: https://doi.org/xxxxx. Cite Them Right does not ask for an accessed date when you cite with a DOI. If there is no DOI and the article is freely available online, include the URL and an accessed date.
How do I reference a source I found through another source (secondary citation)?
Secondary citations (citing a source you read about in another work rather than reading directly) should be avoided where possible. If unavoidable, cite the secondary source in your text and reference list, and acknowledge the original: e.g. (Jones, 2010, cited in Smith, 2020). Only Smith 2020 appears in your reference list.
How many authors before I use "et al." in Harvard?
Cite Them Right, the Harvard version many UK universities and CitApp follow, uses "et al." in the in-text citation from four authors onwards; some Harvard guides start at three (Karlstad University and SLU in Sweden, for example). In the reference list, Cite Them Right guides at some universities allow the first author followed by "et al." from four authors, while others ask for every author. Check your university's guide for the exact rule.
