For a change, try ISBNdb

I read about this at a librarian blog today--I'd never heard of it--I've been gone too long to keep up on all the techie things about library searching. But instead of just linking to Amazon, which many library catalogs do these days (don't know if they get a kick back but they should) this librarian says ISBNdb can offer a range of sites for checking prices and availability. Here's an example.

"ISBNdb.com project is a database of books providing on-line and remote research tools for individuals, book stores, librarians, scientists, etc. Taking data from hundreds of libraries across the world ISBNdb is a unique tool you won't find anywhere else."
