Late last year, I purchased the program "Delicious Library" for my Mac, from Delicious Monster. The application allows you to build a virtual library of your physical books, CDs, DVDs, and other items around the house. You can then use this "library" to check-out items to friends. The innovative part is its use of the iSight video camera (or a Bluetooth scanner) to read barcodes and automatically "know" a lot about the items you scan into the database. With the most recent update, I was able to use the program to look at my iTunes library without the application crashing (was my collection too large? or was the new directory from iTunes 9 the fix?). So, now, I have exported my collection with nice bookshelves to HTML. View my music collection online! I think something worth exploring is whether or not I could review each album and have that display when you click on the CD covers. Hmm...
