As its name suggests, Author-Date uses parenthetical citations in the text to reference the source's author's last name and the year of publication. Each parenthetical citation corresponds to an entry on a References page that concludes the document. In these regards, Author-Date is very similar to, for instance, APA style. The exact format will be dependent on the source type.
