Harvard referencing, also known as the author-date system or parenthetical referencing, was developed at Harvard University in the 1950s and 1960s and is now used by publishers and academics all over the world. Under this system, a source is cited in the text in parentheses immediately after the passage that is based on it, using the last name of the author and the year of publication only, as in (Author 2005). Other refinements are added for a special situation, such as multiple authors or an author with multiple publications in one year.
NOTE: This citation style has no official institutional affiliation with Harvard University. Some Harvard faculty were among the first practitioners and the name stuck, particularly in England and the Commonwealth countries.
