Harvard style is the author-date system used in many universities, especially in business, social sciences and the humanities. The in-text citation gives the author and year in brackets, and the reference list at the end gives the full details in alphabetical order. It looks simple, but the punctuation — commas, brackets, single quotes around article titles — trips up many students. This free Harvard reference formatter builds a correct reference from the details you type, following the common Harvard author-date rules used by UK universities. It covers journal articles, books and websites.

What Harvard style requires

A Harvard reference starts with the authors, surname first with initials, joined by and for two authors, or shortened to the first author plus et al. for three or more. The year sits in brackets right after the authors. The title of a journal article goes in single quotation marks, while a book title is italicised. The journal name follows, also italicised in a finished paper, then the volume, the issue in brackets and the page range introduced by pp. A DOI closes the entry when one exists. Website entries add Available at with the URL and the date you accessed it.

How to use the formatter

Type each author on its own line as Last, First, for example Smith, John.
Pick the source type: journal article, book or website.
Fill in the year, the title, and the journal name or publisher.
Add the volume, issue and page numbers for a journal article.
Paste the DOI or URL if you have one, then click Format reference.
Copy the result or download it as a text file.

A worked example

For an article by Smith, John and Garcia, Maria, published in 2024 in the Journal of Learning, volume 12, issue 3, pages 45 to 67, the formatter produces: Smith, J. and Garcia, M. (2024) ‘A study of study habits’, Journal of Learning, 12(3), pp. 45–67. doi: 10.1000/example. Notice the single quotes around the article title, the and between the two authors, and pp. before the pages. Those small marks are the Harvard signature, and markers notice when they are missing.

Harvard is not one single style

One warning matters more than any other: there is no single official Harvard manual. Different universities publish their own Harvard guides, and they disagree on details such as whether to use p. or pp., how to show DOIs, and how to format website access dates. That is why this tool follows the most common conventions, and why you must check your own university’s guide before submitting. A reference that is perfect at one university can lose marks at another for a detail as small as a comma.

Common Harvard mistakes to avoid

The most common error is putting the article title in italics instead of single quotes, or the journal name in quotes instead of italics. Another is forgetting the brackets around the year, or writing et al. for two authors when Harvard wants both names. Students also drop the pp. before page numbers, or forget the access date on website entries. Finally, check that the reference list is alphabetical by first author’s surname and that every in-text citation has a matching full reference.

Formatting aid, not a final authority

This tool is a formatting aid only. It follows common Harvard author-date conventions for the usual cases, but your institution’s guide is the final authority for your work. Always check that guide, especially for websites, chapters in edited books and sources with no author or date. When a source does not fit the form neatly, check your university guide or ask your tutor before you submit.

Frequently asked questions

Single or double quotes? Harvard commonly uses single quotes around article titles.
What if there is no date? Use n.d. in place of the year, which stands for no date.
Do I list all authors? For three or more authors, most Harvard guides use the first author plus et al. in the reference list.
