The Book That Changed the World Hidden Treasures at the Library of Congress

By introducing printing with moveable metal type to Western Europe, Johann Gutenberg revolutionized books, and, in fact, the very nature of communication. Text, once scarce and complicated to produce, was now easily created in multiples that were readily distributed. Out of the explosion of text enabled by moveable type came the Renaissance, the Reformation and the Scientific Revolution. The Bible, too, became a transformed document.
