This is an incredibly helpful add-on...and the latest version (0.7) is extensible, so if you have a little skill at coding, you can easily add a library that's not on the included list. If you're not so good at coding, there's a guide to get the information to the developer to help get your library added. I can't sing the praises of this add-on enough...comparison shopping in a single window, and jumping from Amazon to on reserve at my library in just a few clicks? I'm a happy bookworm.This review is for a previous version of the add-on (0.7).
