Not Crypto: Referencing Electronic Texts

This has nothing to do with crypto, but it's a question I'm sure a few people on the list have had to deal with this as well... I'm doing a research project for a class on the problems of making scholarly references to electronic documents, mainly on the how-tos (for author writing document as well as one who cites an electronic document in footnotes and bibliographies), as well as some technical problems (sites change or go down, documents are modified by author or hacker who doesn't indicate a modification, etc..). Any information, URLs, references, personal anecdotes, methods, tips, etc. would be greatly appreciated. (Please reply to me and not the list unless you find some bizarre way of relating this to crypto...) Thanks, Rob
