Book Search Tips: A Guide to Finding Out-of-Print Books on the Net

Auctions

Popula - Very hip little auction which specializes in the collectible and the weird.
Books by Bid - Auction which specializes in books & ephemera.
eBay.com - An online auction. At any given time, they may have tens of thousands books up for auction (last time I looked - 24,425). Be cautious here, because not all of the sellers are knowledgeable. If you are looking for a particular edition, or collectible condition, you'll have to ask a lot of questions before you bid just to be sure.
