Create a Citation
There are two main steps to creating a citation:
Cite within the text of your paper with parenthetical references or footnotes. Provide the exact page number of the passage you're citing.
Make a list of all the works you cited. This page is called Works Cited, References, or Bibliography, depending on which citation style you use. Order items alphabetically by author's last name.
