There are now e-readers. Some are called a "Nook" and "Kindle". You can also use your internet on a computer. Go to Google or another search engine and look for "e-books". There are hundreds you can download for free. Your Kindle will also download books, but with a Nook, you can first download to a computer then attach the Nook and transfer the book to your hand-held e-reader.
You can purchase e-books from Amazon.com and then download it to your e-reader or computer. Some city libraries will now let you borrow e-books from the library if you belong to the library and use their procedure. The book will automatically be cancelled when the book time runs out. This is free also.
