What is the outline or structure used in writing a literature review with an APA format?

I found two examples of the APA format for Literature Reviews. American Psychological Association Style Works a2 www.owl.englis.purdue.edu. At this site there is a lab as well as the format and explainations of what each part should be about and look like. On the www.people.wcsu.edu site, they explained what a Liturature Review is comprised of and some of the logistics, in a very short format.
