Establishment
Pope Nicholas V established the library in the Vatican in 1448 by combining some 350 Greek, Latin and Hebrew codices inherited from his predecessors with his own collection and extensive acquisitions, among them manuscripts from the imperial Library of Constantinople. The Biblioteca Apostolica Vaticana was established in 1475.
When its first librarian, Bartolomeo Platina, produced a listing in 1481, the library held over 3,500 items, making it by far the largest in the Western world. Around 1587, Pope Sixtus V commissioned the architect Domenico Fontana to construct a new building for the library; it is still in use today. Books were displayed on benches to which they were chained.
