Abstract

Colon Classification (CC) is truly the first freely faceted scheme for library classification devised and propagated by Dr. S.R. Ranganathan. The scheme is being taught in theory and practice to the students in most of the LIS schools in India and abroad also. Many manuals, Guide books and Introductory works have been published on CC in the past. But the present work tread a new path in presenting CC to the student, teaching and professional community. The present work Colon Classification: Theory and Practice; A Self Instructional Manual is the result of author's twenty-five years experience of teaching theory and practice of CC to the students of LIS. For the first ime concerted and systematic attempt has been made to present theory and practice of CC in self-instructional mode, keeping in view the requirements of students learners of Open Universities/ Distance Education Institutions in particular. The other singificant and novel features introduced in this manual are: Presenting the scope of each block consisting certain units bollowed by objectives, introduction, sections, sub-sections, self check exercises, glossary and assignment of each unit. It is hoped that all these features will help the users/readers of this manual to understand and grasp quickly, the intricacies involved in theory and practice of CC(6th Edition). The manual is presented in three blocks and twelve units.

Abstract

During the twentieth century, bibliographic classification theory underwent a structural revolution. The first modern bibliographic classifications were top-down systems that started at the universe of knowledge and subdivided that universe downward to minute subclasses. After the invention of faceted classification by S.R. Ranganathan, the ideal was to build bottom-up classifications that started with the universe of concepts and built upward to larger and larger faceted classes. This ideal has not been achieved, and the two kinds of classification systems are not mutually exclusive. This paper examines the process by which this structural revolution was accomplished by looking at the spread of facet theory after 1924 when Ranganathan attended the School of Librarianship, London, through selected classification textbooks that were published after that date. To this end, the paper examines the role of W.C.B. Sayers as a teacher and author of three editions of The Manual of Classification for Librarians and Bibliographers. Sayers influenced both Ranganathan and the various members of the Classification Research Group (CRG) who were his students. Further, the paper contrasts the methods of evaluating classification systems that arose between Sayers's Canons of Classification in 1915- 1916 and J. Mills's A Modern Outline of Library Classification in 1960 in order to demonstrate the speed with which one kind of classificatory structure was overtaken by another.
