New improved Book Burro extension for Firefox
Jesse Andrews has updated his awesome Book Burro extension for Firefox to include library lookups in addition to price comparisons. I sent him an email two days ago asking that the Seattle Public Library be added to the list of available libraries, and today he let me know that SPL has been added. And it works. Check out this screenshot:

Book Burro is way better than any lookup script I have seen. And it looks like he’s working on a new feature for adding your own custom sources. Go get Book Burro now.
