A.P.A formatt referencing?

this site is amazing for that http://owl.english.purdue.edu/owl/resource/560/10/

here’s an example

Online Encyclopedias and Dictionaries Often encyclopedias and dictionaries do not provide bylines (authors’ names). When no byline is present, move the entry name to the front of the citation. Provide publication dates if present or specify (n.d.) if no date is present in the entry. Because updates and modifications are not normally specified, provide the retrieval date in the citation. When listing the URL, give only the home or index root as opposed to the URL for the entry.

Feminism. (n.d.) In Encyclopædia Britannica online. Retrieved March 16, 2008, from http:// www.britannica.com

Nonperiodical Web Document, Web Page, or Report List as much of the following information as possible (you sometimes have to hunt around to find the information; don’t be lazy. If there is a page like http://www.somesite.com/somepage.htm, and somepage.htm doesn’t have the information you’re looking for, move up the URL to http://www.somesite.com/):

Author, A. A., & Author, B. B. (Date of publication). Title of document. Retrieved month day, year (only if the text may potentially change over time), from http://Web address

NOTE: When an Internet document is more than one Web page, provide a URL that links to the home page or entry page for the document. Also, if there isn’t a date available for the document use (n.d.) for no date.
