Just as email has changed the way
we write to each other, e-books are
changing the way we read. We can
easily download new e-books from the
Internet. It is much easier and quicker to search for passages now, and we can also write notes in an e-book. What is more, they save a lot of paper. But e-book readers are still more expensive than paper books, so not all people can afford them. However, with the rapid development of electronic technology, reading e-books will become cheaper and cheaper. A lot of people think there will be more e-books than paper books in the near future.

Today
Vinton Cerf and Bob Kahn are often called Fathers of the Internet.
After printing was invented, knowledge was spread around the world by books. For many years, books were very expensive. Each one was written by hand, so very few books were produced. Today, books are produced quickly. They’re light, cheap and easy to get hold of.
But the early books are now too valuable to be picked up and held in the hand, so here in the British Library, they were copied onto a computer a few years ago. Have a look at the screen here. You can turn the pages on the screen, without touching the real books.
Tapescript
The Internet has been around for many years, but it was the invention of the World Wide Web that made it really useful to people. Together, the Internet and the World Wide Web have changed the world.
