Many important catalogues of special classes of mss. and im. portant single volumes have been published in facsimile. A new catalogue of the printed books was made in 1927-29 to make easily available the library's rich treasures. This catalogue, made possible by the aid of the Carnegie Endowment, was worked out mainly according to the code of the American Library Associa tion by four Vatican librarians and four American librarians.
The Biblioteca Casanatense, founded by Cardinal Casanate in 1698 (131,778 printed vols., 2,086 incunabula, with many Roman and Venetian editions, and 6,124 mss., some of the 8th–ioth centuries), is rich in theology, mediaeval history, law and the social sciences. An incomplete catalogue of the printed books by A. Audiffredi (1761-88) still remains a model.
The Biblioteca Angelica, founded in 1614 by Angelo Rocca (120,00o printed vols. and 3,00o mss.) was the first library in Rome to be opened to the public. The library of the University of Rome is the Alessandrina, founded by Alexander VII. in 1661, with the greater part of the printed books belonging to the dukes of Urbino, and opened in 1676. In 1815 Pius VII. granted to it the right to receive a copy of every book printed in the States of the Church, which grant was continued by Italian law but limited to the province of Rome. The library possesses 200,00o printed books.
The library of the Senate, established at Turin in 1848, contains 130,289 vols. rich in the history and statutes of Italian cities. That of the Chamber of Deputies (1848) contains 250,00o vols., and specializes in more modern history, law and politics. The
Vallicelliana (1581), controlled by the R. Society Romana di Storia Patria has some important mss., including one attributed to Alcuin; the Lancisiana (17i I), is valuable for its medical col lections; the Accademia di San Luca possesses a good art library; the Biblioteca Militare Centrale (1893) has ioo,000 printed vols. and 72,000 maps; and the Biblioteca della R. Accad. di S. Cecilia (1875), a musical collection of 15o,000 vols. and 6,000 mss.; the Corsiniana, founded by Clement XII., is rich in incunabula and prints, and, since 1884, belongs to the Accademia dei Lincei. The Deutsches Institut, Ecole Francaise and British and American Schools, and the International Institute of Agriculture may be mentioned. All these and many other Roman libraries are open, at least to advanced students.
