From the clay tablets to the e-book format, the book has enjoyed a remarkable evolution.Through history, many different materials have been used for books, such as beech bark and bamboo. In Mesopotamia, cuneiform tablets were made from clay and bore little resemblance to books today.
It is a little-known but undisputed historical fact that Johannes Gutenberg did not invent the printing press. Though the Gutenberg Bible was certainly the first mass produced printed work, it was hardly the first printed book. Chinese and Korean inventors had been producing printed books for centuries before Gutenberg was born. The first printed book printed paper book that we can reliably date is the Chinese book, Diamond Sutra (pictured above), created in 868.
