NAUD, GABRIEL

born Feb. 2, 1600, Paris, Fr. died July 30, 1653, Abbeville French physician and librarian, considered the first important theoretician of modern library organization. His treatise, Advis pour dresser une bibliothque (1627; Advice on Establishing a Library), was the first important study of library science. Naud studied medicine at Paris and Padua and practiced after 1626, but his first love was books and libraries. In 1629 he was called to Rome as librarian to Cardinal Bagni and later Cardinal Barberini. He had occasion to expose a falsely attributed book for Cardinal Richelieu, who then called him to Paris as his own librarian, and got him the honorary title of physician to King Louis XIII. He became librarian to Cardinal Mazarin in 1643, when the latter succeeded Richelieu as first minister of France. For Mazarin he collected some 40,000 books from all over Europe to constitute the Bibliothque Mazarine, widely acclaimed as the best library of the period. In accord with the cardinal's wishes and his own, Naud made the library's motto, Come in, all you who desire to read; the library was free and open to all. Adapting a library cataloging system devised earlier, Naud used the following classifications for books in the Bibliothque: theology, medicine, law, history, philosophy, mathematics, and humanities and the appropriate subdivisions. The Bibliothque Mazarine was dispersed during the uprisings of the Fronde (164853), and Naud was exiled to Sweden. He died en route to Stockholm.
