Incredible Book & Sheet Music Finder
I appreciate this app a lot as a music student. Many full scores and sheet music pieces are not available in my small school library, but this app has almost everything. Most of music theory books and fake/real books are heavy, but this app made me possible to carry only iPad or iPhone when I have too many books in my bag. I can review expensive books before order them on Internet stores, too. $9.99/month monthly charge is bit pricy for starving college students, but its very useful app.
