A student pursuing a degree in the humanities can expect to run through 1,000 books before graduation day. A wealthy family in England in 1250 might have owned three books: a Bible, a collection of prayers, and a life of the saints—this modestly sized library nevertheless costing as much as a cottage. The painstaking craftsmanship of a pre-Gutenberg Bible was evidence of a society that could not afford to make room for an unlimited range of works but also welcomed restriction as the basis for proper engagement with a set of ideas.
