Do you have the APA manual?
Wolfgram Library has copies of all style manuals, including the Publication Manual of the American Psychological Association. (6th ed.) (2010). Washington, DC: American Psychological Association (APA), behind the reference desk.
These print sources include accurate and up-to-date examples for all types of sources that you may encounter.
