As you write your paper, your Professor may ask you to use the Author-Date System of CMS. This means you must cite your sources within the text of your paper. These are called in-text or parenthetical citations. The natural and social sciences use this system most often, but again clarify with your professor if you are unsure which they would prefer.

(Last Name Year)
(Last Name Year, Page Numbers)
(Last Name, Last Name, and Last Name Year)
(Last Name et al Year)

A reference list must always accompany the text citations. The reference list is included at the end of the paper and includes the full citation for each source.
