The gutenberg bible of 1454:

When it comes to revolutions in public knowledge, the Gutenberg Bible is up there with the Internet. As the first major Western publication to be printed using movable metal type, this extraordinary technological and artistic feat heralded the age of the printed book. This meticulous reprint reproduces the Göttingen Library edition, one of the very few surviving complete vellum Latin originals worldwide, listed in the UNESCO Memory of the World program.
