How to cite in Harvard
Harvard is an author–date style: in the body of your text you give the author's surname and the year of publication in parentheses — (Chen, 2021) — and every source is listed in full in a Reference list at the end. Add a page number for direct quotes, as in (Chen, 2021, p. 47). Two authors are joined by the word and, never an ampersand, and you only switch to et al. at four or more authors. For the full rules and worked examples, read our Harvard citation guide.
In the reference list, invert the first author as surname-then-initials with no spaces (Chen, M.S.) and place the year in parentheses after it. Book titles are italicised in sentence case, journal names are italicised in title case, and article and chapter titles sit in quotation marks in sentence case. Online sources are prefixed with Available at: and an access date, while DOIs use the same prefix without a date. Entries are alphabetised by surname and set with a hanging indent.
Remember that "Harvard" is a family of conventions rather than one official standard — this tool produces the widely cited Cite Them Right variant, but your institution may publish a slightly different house style, so check your assignment brief if it names a specific sheet.
