How do I cite these sources in APA format? I nearly completely forget how to format this correctly in APA format, could anyone...

As noted by the prior poster, APA format has recently undergone a revision, so be sure that you are using the 6th edition (if that is what your professor expects). All of the sources that you have listed are electronic sources, but even electronic sources can be different in terms of the details that you need to include. You will always begin by citing the author last name, followed by first initial. Then, in parentheses, follow this with the date of publication. You will then include the title of the work and the relevant publication information (Retrieval date and URL for a web page; doi for a database article, city and publisher for a print source)

For example, a database article would be cited like this:

Steinbrook, R.. (2009). Lobbying, Campaign Contributions, and Health Care Reform. The New England Journal of Medicine, 361(23), e52.  doi:1914852231

A web page like this:

Political Advocacy (2010) Directory of United States Lobbyists. Retrieved March 17, 2010 from http://www.vancouver.wsu.edu/fac/kfountain/

And a book like this:

Bogosian, E. (2008) Talk Radio. New York: Samuel French.

The absolute best source that I have found for APA is the OWL. Here is their page for on line sources:

Also, don't forget to include an in text citation for each time you use a source - for example, using your source above: (Paz, 2010).
