In the olden days when books were made by hand, a scribe would have to copy out the writings onto parchment. He was not allowed to make any mistakes! All day long he would just sit and copy down words using pen and ink.

Long ago, the Chinese used silk to make their paper. They were the first people to start printing books instead of just writing books. But then they stopped and many years later a German, Johannes Gutenberg, started printing books again. The first book he printed was the Bible.
