follow-up to the last post: if you are looking for a specific book and are in the united states, check worldcat. It has access to the catalogues of every public, university, and special library that belongs to OCLC (which is just about everyone), and will tell you where you can find the book (this includes digitally, such as through hathitrust and internet archive). And even if the thing you're looking for is far away, being a member of OCLC means they probably participate in inter-library loans, so you can request the book through your local library.

please use worldcat. it's wonderful. tell everyone you know
