The
Cornell University (Ithaca, New York) Library
has a reasonably
accurate summary of some of the key aspects of APA citing and
references. You might look at their web page
http://www.library.cornell.edu/newhelp/res_strategy/citing/apa.html
for assistance.
Alternatively, you
might look at
Concordia University Libraries (Montréal,
Canada)
summary, which is also
good:

There are any number of
other summaries of APA style online. Unfortunately, many are inaccurate. If you are
writing at a graduate student level or above, there is really only one reference - the
definitive one:
American
Psychological Association. (2001). Publication Manual of the American
Psychological Association (Fifth Edition). Washington, DC: Author.
It is a 450 page book, but is the definitive
source. Only a fraction of it deals with citations and references. We use mainly the chapters dealing with references
(all of Chapter 4, Section 5.19 of Chapter 5, and Appendix D) and citations (Sections 3.94-3.103) as the
specifications for the CiteRefs software. We also conform to the tables of
acceptable abbreviations given throughout the book.
