Citation produces a lot in anxiety in paper writers, particularly when it's something we don't do on a regular basis.
The good news is that citation is not magic, is has a definite set of rules that you need to follow carefully, a little like a recipe or a line of computer code.
Refer to the following resources for examples on APA reference lists and in-text citations (these are the notes you
make within the paper)
The Publication Manual of the American Psychological Association, 6th Edition.
Search CityCat for the location. Copies available at Rosenberg, Alice Statler, John Adams, and Mission.
Beford St. Martins (Diana Hacker) APA Research and Documentation Online
This is my personal favorite tool for managaing APA citation. Contains lots of examples and the rules of in-text citations, as well as a full sample paper and refererence list.
Purdue OWL APA Another great, extensive APA resource site with lots of examples.
Via Article Databases:
Both Gale (Health and Wellness Resource Center) and EBSCO (CINAHL, AltHealthWatch) offer automatic citation generator tools for your reference. But be advised that these often contain errors. I recommend starting with the auto-citation, and then referring to the OWL or Bedford St. Martins site to check it.
