Printing from wood locks began in China, perhaps in the 10th century, developed by Buddhists and Taoists. The oldest printed texts so far discovered are Buddhist sutras (collections of maxims). During the Five Dynasties, the Confucian classics were printed for the first time. Moveable type arrived soon after, but convenient block printing continued as the common method of printing.

Johann Gutenberg (1397?-1468) perfected the process in the German town of Mainz. In 1457 his son-in-law, Johann Fust printed the oldest surviving dated book, an edition of the Psalms in Latin. The famous "Gutenberg Bible" was printed 1453-55.

The printing of Bibles promoted "The Protestant Revolution" and spread of both religious and secular education -- as, for example, in the work of Martin Luther (1483-1546). (Lecturing began in the Middle Ages when only the teacher had a book -- a hand-written one -- and read it to his students.)

Today, "The Gutenberg Revolution" is the worldwide Web, as my case shows. I've put ONLINE material which has been suppressed from 1957. And the same option is open to millions around the world.
