This app lets you scan the ISBN on books and it will load them onto a virtual bookshelf. The app pulls the information from the internet and when you add a new book, it provides so much information for you (if it is part of a series, who published it, a description, a picture of the cover, how many pages). It also allows you to edit the books on your shelves as well. You can give a rating, note if you read the book, indicate when you started and finished the book, and you can note if you loaned the book to a friend! The best part is that you can organize your books in SO many different ways (author’s last name, unread books first, title, series, genre, publication date, date added, etc).
