Note: Webpages that appear to have no author usually have a corporate author that takes responsibility for the content. If no one takes responsibility for the content, then you should be very, very cautious about citing it, but if there truly is no author, then start the citation with the title of the webpage.

Avoid citing Wikipedia. If you need to use information from Wikipedia, look in the "References" and the "External Links" sections for credible sources for that information. If you can't find a better source for the information and simple must use it, then include the date that you accessed it in your citation.
