APA: Reference List Guide
The purpose of a reference list is to provide enough unique information so a reader can retrieve listed items easily in a library search. When in doubt provide more information rather than less. The "Publication Manual of the American Psychological Association," (Sixth Edition) was used to construct this guide.
