This is one of the best places to waste some time, in my opinion. It's fairly large, all the books are in distinct sections, and sometimes you can make some really good finds. I'm mostly a fantasy/sci-fi reader, so I can only speak to that area, but I'm sure it works for them all. They've got a nice variety of newer used books, sometimes ones that have just come out, and also much older used books, which may or may not be out of print. I know I personally have found at least a few books there that I would otherwise probably never have heard of, or been able to find. And you can't beat the prices.
