North America Imprints
About 45,000 titles were printed in North America (exclusive of Mexico) before 1801. Of these about 40,000 are extant. The JCB has over 11,000 titles; when combined with the 1800 works in the John Hay Library of Brown University, those 13,000 books constitute one of the four largest collections of early American imprints. Especially notable holdings include the Bay Psalm Book (1640), the Eliot Indian Bibles (1661-1663), and the early Saur Bibles of Germantown, Pennsylvania (from 1743).
