The Answer:

There are lots of permutations to citing a source. Is the article from periodical that you read online; is it an online newspaper; is it a site that is not in print? And the APA periodically updates their style. Basically you need the name of the article, the date you read the article, and the URL of the page.

Here is the general structure for an online periodical:

Author, A. A., Author, B. B., & Author,
   C. C. (2000). Title of article. Title of
   Periodical, xx, xxxxxx. Retrieved month
   day, year, from source.

Here is the general structure for an online document:

Author, A. A. (2000). Title of work.
   Retrieved month day, year, from source.
