I attempted to use the NetLibrary link and get a login to download a book but it came up with an error. So instead, I checked out their "About Us" page and learned what it is they are trying to do. I like he concept of ebooks and the epublications catalog. I think this is an incredibly relevant and useful tool for libraries.
I do wonder, though, has this taken off? Are many libraries using ebooks? If so, how have they implemented this technology? Does the patron get a user ID and password and "checks out" the book for a certain amount of time? Or does the book remain indefinitely available in the patron's account?
