Here is a template to start you out on the correct formatting for your APA paper.
General Format of the References Page
The references page is double-spaced from top to bottom, just as the rest of the paper is double-spaced. The label References is centered; the page is numbered along with the rest of the paper. The first line of each entry may be indented; or the first line may be flush with the left-hand margin, and the second, etc., lines of the entry are indented. APA accepts both methods of indenting, but only one method may be used at a time. Ask your professor
