Google gave a few fresh features to Google Books. First, updated the home page by adding the ability to scroll through categories of books and magazines. Also integrated “My Library” to enable you to create and then share collections of books by adding them to "bookshelves." This new version of My Library gives you control over your collections by enabling you to keep some bookshelves private--if, say, you want to organize your own personal reading lists--while sharing others. Previously, all books in your My Library were part of a single collection, and you could tag books with labels to organize. Now, instead of tagging a book with a label, you can add it to one or more bookshelves. As part of this transition to bookshelves, we're migrating all the previously created labels to the new bookshelf system.
