Actually, you can just go to ANY regional library and look under section 700+ (can't remember the exact one) for photography related books. They've got a wide array of materials covering many aspects of photography for you to choose from. Personally the publishers that I like are Amphoto, Amherst Media, Rotorvision, Page ONE and Pro Photo.
If all else fail, just use the OPAC machine and look up keywords and then find the book that you want and check which libraries have it. Good luck!
