Stanford Encyclopedia of Philosophy
I can’t believe it has taken me this long to find The Stanford Encyclopedia of Philosophy. For a free, reliable, online resource it is utterly amazing. Granted you can’t find articles on any little thing you are interested in (like you would probably be pretty hard pressed to find anything on paperclips or bananas) but if you want to do research on any matters concerning philosophy, religion, or scientific theories I would say this site is a very good place to start off (and because of its rigorous editorial process and regular updates it is a site that I think one could use a reasonably legitimate source as opposed to the questionable validity of, say, wikipedia). Very very cool . . . I will probably be spending a lot of time reading stuff on the SEP.

Why I win with this find: I mentioned the site to my boss telling her that I thought it would be a valuable tool to add to our online reference resources. She had not seen it before either and was really impressed and said she is going to see about getting the link added. Bonus points for me. Smiles.
