The new library site offers something I often wish the old one had, the ability to search for available books. I tested it last night and couldn't get the book to down load onto my Nook. I have it in an odd form. It is an old book so I'm not sure what is the cause.
I just browsed, using the computer which is easier, and couldn't find another book to test using my Nook. I did figure out the original reason I couldn't get the library app to work on my Nook, it was just too darn slow.
