Don’t be shocked that I’m posting a link to Wikipedia. I use it all the time to get a quick take on something, keeping in mind that I have no idea who wrote it or how credible they are–”studies show” that Wikipedia is actually more often credible than conventional (and now defunct) print encyclopedias. That being said, however, scholars typically don’t cite encyclopedias as sources, so do try to resist the temptation to rest in their authority.
