If you’re a librarian, you either warily love or wholeheartedly hate Wikipedia. It is completely capable of propagating large amounts of misinformation. It also has a whole world of contributors and editors. I myself am a wary lover: I like it as a starting point, but would always double-check anything I found there.
Sometimes I wish I had fact checkers like in this film (note: I got so, so tired of YouTube clips a couple of weeks ago I thought I wouldn’t post them anymore, but, alas, this one is irresistible… if you only want to watch the Wikipedia reference, fast forward to 1:50, but highly I recommend watching the entire film. It’s for your own good.):
