During the Enlightenment more books began to pour off European presses, creating an early form of information overload for many readers. Nowhere was this more the case than in Enlightenment Scotland, where students were exposed to a wide variety of books during their education.[19] The demands of the British and Foreign Bible Society (founded 1804), the American Bible Society (founded 1816), and other non-denominational publishers for enormously large inexpensive runs of texts led to numerous innovations. The introduction of steam printing presses a little before 1820, closely followed by new steam paper mills, constituted the two most major innovations.
