Vatican Apostolic Library
From the Vatican Apostolic Library: From the fourth century onwards there is evidence of the Scrinium of the Roman Church, which was both a library and an archive. In a document dated to 784, under Pope Adrian I, the figure of the Bibliothecarius of the Roman Church appears. The title was given to the Librarian Theophylactus. The earliest library and archive of the Popes were dispersed, for unknown reasons in the early 1200's.
