Sources are listed in two places.
The first, a citation, is briefly listed within your answer. This includes identifying information that directs the reader to your list of references at the end of your writing assignment.
The second, a reference, is at the end of your work in the list of references section.
All sources cited should follow APA style and provide enough identifying information so that the reader can access the original material.
