This is a basic Quick Tip, but one that can really help you out if you want to remove or restore a book in your library. This is especially helpful if some of your books have become locked and you know you are not going to purchase them in the future. Removing these books can organize your library and open up space on your hard drive. Removing locked books can help you clear out your library at certain times when you know you won’t use the book or are finished with it, and you can always restore these books later on when you want to use them and see them back on your shelf.
