Consider the plight of the medieval scholar. Before the advent of movable
type, scholarship was greatly hindered by a lack of access to necessary texts.
Even a journey to the library of a far-away monastery did not guarantee finding
one of the few existing copies of a book, and the volume, once found after
a long search, might prove to be a faulty copy produced by a careless scribe.
Gutenberg's invention of printing from movable type revolutionized scholarship,
leading to an explosion of new knowledge. Any number of copies of exactly
replicated texts could be produced, greatly enhancing the probability that
the scholar would come across the needed information, and in turn produce
new information that could be shared with others.
