THE BRUNET SYSTEM. — Originating from the catalogue of the Thuana Library of 1679, modified around 1700 by P. Marchand, between 1711 and 1760 by G. Martin, later by De Bure, and finally by Brunet, from whom it took its name, in two successive editions of his Table méthodique (Paris 1842 and 1865). It comprises five main classes: 1. Theology; 2. Jurisprudence; 3. Sciences and arts; 4. belles-lettres; 5. History; each divided into categories. These in turn branch into various divisions and subdivisions. It is the system that served as the basis for all subsequent developments and is still used in some libraries in France.
**THE CROZET C.B.** — Developed in the Manuel pratique du bibliothécaire (Paris 1932), it consists of ten divisions: 1. General works; 2. Religions; 3. Philosophy; 4. Pure sciences; 5. Applied sciences and technology; 6. Fine arts; 7. Languages and literatures; 8. Geography; 9. History of peoples; 10. Social sciences. Each division includes various subdivisions.
**THE DECIMAL C.B. SYSTEM.** — Devised by Melvil Dewey for the library of Amherst College, Massachusetts (1873), and then applied by the same inventor to the libraries of Columbia College in New York and the University of Albany, it was expanded and disseminated by the Belgians La Fontaine and P. Otlet, who for this purpose founded the International Institute of Bibliography in Brussels in 1895, with the aim of achieving universal application. According to this system, human knowledge is divided into 9 classes, each class into 9 divisions, each division into 9 sections, each section into 9 subsections, and so on, each numbered with digits from 1 to 9; zero is reserved, within each subdivision, for general works. The classes are as follows: 1. Philosophy; 2. Religion; 3. Sociology; 4. Philology; 5. Pure science; 6. Applied science (useful arts); 7. Fine arts; 8. Literature; 9. History. Each work is thus characterized by a number, with as many digits as the subject is detailed: e.g., a general encyclopedia will be 23 (third division of the class of general works), but an Italian encyclopedia 35 (fifth section of the third division of the class of general works); and the work by M. Rosi, L'Italia odierna, will have the number 945.08, i.e., class 9 (History), division 4 (Europe), section 5 (Italy), subsection 8 (Risorgimento wars). Specifications can be extended indefinitely, and become necessary within each class or division when the system is applied to specialized libraries. In particular, for ecclesiastical libraries, detailed developments of class 2 (Religion) have been made: cf. J. Murphy Lynn, An alternative classification for Catholic books: a scheme for Catholic theology, Canon law and Church history (Milwaukee 1937), and P.-A. Martin, Religion, theology, droit canonique: classe 2 et division 348 de la classification décimale (Montréal [1938]). For the purposes of bibliographic classification, the decimal system
