myBooks - the one and only book catalog application you want on your iPhone/iPod Touch - is available in the App Store.

myBooks is a book catalog application with stunning graphics. It allows you to quickly add, find and view books in your library (with the ability to add new movies by seeking by title using amazon.com - so all book details are filled in for you!). It also allows to lend books to friends, so you can easily keep track of who you gave that copy of "The Da Vinci Code" to.
