Harvard referencing style (also known as author-date style) is a generic description for any referencing style that uses in-text citations with an author and date. In that sense, APA style is a type of Harvard referencing. However, many individual styles describe themselves as Harvard. They vary from source to source in small details (such as reference punctuation).
If you have been instructed to use Harvard style, the Australian Style manual for authors, editors and printers offers the most common and consistent description. It is summarised in brief below. Your course, department, school, or institute may prescribe specific conventions, and their recommendations supersede these instructions.
Harvard in-text citations are nearly identical to APA citations, but do not put a comma between the author(s) and year of publication:
…common at the time (Jones 2005).
Like APA, direct quotations must be accompanied by page numbers:
…without a doubt” (Jones 2005, p. 22).
Like APA, secondary sources (works cited inside other works) use both authors' names:
…some uncertainty” (Nguyen, cited in Jones 2005, p. 22).
The individual parts of a reference list entry (title, place of publication, etc.) are separated with a comma. As in APA, entries are alphabetised according to author.
Order: author, year, book title, publisher, place of publication.
