If you've been collecting music since the Napster days of the mid 90's you know the value of a product like TuneUp for iTunes. It helps you tag your music with the Cover Art and the proper tags. I was wondering if anyone knows of such an application/plug-in/app that can do that sort of thing only for iBooks. I have a bunch of PDF, Magazines, etc. They aren't tagged for crap and makes it very cluttered. Thanks.
