I remember college professors being very anal about citing sources. I think citing a book with a certain publisher and publication date would be considered more authoritative than "I found it on this website".

They are. A creative student could the page number and the publishing info off the internet and cite the material as a pamphlet or a book. Just a thought. Not that I've ever done that or anything.

It is perfectly acceptable to cite an Internet source. Most (American) professors recognize this since Harbrace released the edition with instructions on citing Internet sources.
