Our Library have most of the books on CD's now for check out or downloadable, they still call it books on tape. There are also pre-loaded units that have just one book on them all you have to do after checking them out is make sure the AA battery works. I have a Sandisk that I listen to books and music on while I work, its small and easy to wear. The only difficultly may be the size of the screen to select the different books. I can store up to 16G of books, some where between 20 and 40.
