Paper was first created about 2000 years ago, and hasbeen made from silk, cotton, bamboo, and, since the 19th century, from wood. People learned to write words on paper to make a book. But in those days, books could only be produced one at a time by hand. As a result, they were expensive and rare. And because there weren’t many books, few people learned to read.

Then printing was invented in China. The first printed books were made by putting ink on a wooden block and holding the paper against it. When printing was developed greatly at the beginning ofthe 11th century, books could be produced more quickly and cheaply. As a result, more people learned to read. After that, knowledge and ideas spread quickly, in a way thatcan be pared with the introduction of the Internet in the 20th century.

But will books be needed in the future? Today information can be received online, downloaded from the Internet rather than found in books, and information can be kept on CD-ROMs or machines such as MP3 player.These machines are smaller and lighter than books so that they can be carried very easily.
