Bartleby.com is the best Web resource I’ve seen in a long time. It’s a solid, fast, all-in-one-place site with quality reference books ranging from the Columbia Encyclopedia through Strunk and White’s Elements of Style past Bulfinch’s Age of Fable to Gray’s Anatomy. Sweet. If that’s not enough, there’s also an extensive collection of verse, an equally extensive collection of fiction, and a big fat bunch of essays. Yeah, it’s all free.
