I find Wikipedia an excellent "refresher" when I can't remember dates, but I can't imagine anyone thinking they could use it as a reference - the articles are all anonymous and can be modified by anyone. Colleges usually give incoming students a quick course in writing papers and what sources are acceptable, so I would assume they would explain why Wikipedia is not. One excellent thing our wiki does is to record each change, what it was, who made it, and when. Diane Whitehead
