Have you ever heard of e-books? E-books are electronic books. They are no larger than an ordinary book, with a screen on which you can read.

How does the e-book work?

First, you call up websites on your computer and select books that you want. There are thousands of books provided by different websites on the Internet. Then download the books you like on to your e-book. You can download about 10 books at a time. Now you can just sit back and enjoy yourself reading.

Compared with ordinary books, e-books have many advantages. First of all, e-books save space. You can put as many as 10 books into a thing no bigger than a pocket radio and then carry it everywhere. You can renew reading materials in your e-book as many times as you like. With the development of e-book technology, probably an e-library will appear. Then you just take your e-books there and download what you want to read. You no longer need to worry about whether your books are over-due or not.
