From the Oakland Public Library, via Pamie:

To all of you unknown to us, with your cybernames and love of books...you have all renewed our sagging faith in humanity. There you are, wherever you are, responding to our need for books, in an unbelievably generous way! People who haven't smiled in months (especially our librarian who opens the Amazon.com mailers and our children's librarians with their precious Captain Underpants!) are giddy thanks to you.

The rest of the letter is here. I still think it's sad they need to resort to this, but a couple giddy librarians in California is pretty good for a Wednesday morning.
