A Reference library

Reading Alan Schom biography of Napoleon Bonaparte; as he set sail on Egyptian invasion, described on page 96. "As part of a theoretically semiacadmic mission, polymath Monge, chemist Claude Louis Berthollet, and their colleagues had ordered dozens of crates of astronomical, chemical, physical, survey, surgical, and pharmaceutical instruments, accompanied by by a reference library of several hundred tomes of science, philosophy, history, and geography, not to metion an array of what proved to be antiquated and all-but-useless maps of Egypt." p.96

Says much about weeding and keeping the collection fresh and current.
