The Author-Date System has long been used by those in the physical, natural, and social sciences. In this system, sources are briefly cited in the text, usually in the parentheses, by author's last name and date of publication. The short citations are amplified in a list of references, where full bibliographic information is provided.
Each example includes an in-text citation (T) followed by a reference-list entry (R).
