[quote name='BigSpoonyBard']It seemed like it happened once they decided they wanted to add a book collection, which got me excited. After sugegsting it might happen, they never updated again.[/QUOTE]
They should have known better than to try that. I mean, imagine the man hours it would take to prepare that kind of info? I don't even think the Library of Congress could make a site like that within any reasonable amount of time because there are WAY more book releases than there ever could be for DVDs, games, or music.
I think the best thing for music is proabably just using some spreadsheet software to keep track of music or books.
