You can search your local library's catalog to find out what books are available in your town or school; you can search Amazon or other resources to find out what books are for sale. But if you want to see what books *might* be out there for your use, Worldcat.Org may be the best place to start.
Worldcat.org is a freely available database of the library catalog entries in tens of thousands of libraries. Results are grouped together so different editions of the same book are together, and for many large libraries, the libraries who have a copy of the book are tagged.
