Books Library allows you to add, edit, delete unlimited number of books (with name, author, isbn, cover image) and sort them to create your own books library, accessible from any device.
Having your library accessible in an app means never forgetting what you already own and never purchasing unwanted duplicates.
If you ever lose the library due to fire, flood, or other disaster you can use the list to rebuild your collection and (depending on your insurance) possibly recuperate some of the money lost.
If you’ve decided to ban yourself from buying new books, every time youre in a bookstore, look at your list and admire all the unread books you already own.
