One of the famous libraries of the world, founded by Cardinal Federigo Borromeo at Milan between 1603,1609. It consists of a single hall, 75 foot by 29 foot, with bookcases along the walls, lighted by large semi-circular windows at each end. The books are procured by agents from all parts of Europe and also from the East. It was one of the first libraries to offer facilities for research, accessible to all students.
