Abstract

Shiyali Ramamrita Ranganathan (1892-1972) has been called the father of the Indian library movement. He developed the revolutionary Colon Classification (CC) from 1924 to 1928, which was published in seven editions from 1933 to 1987. In this article, the evolution of CC through its seven editions is discussed. The unique features of CC are described, including the work in idea, verbal, and notational planes. Tools for designing and evaluating a system are enshrined in his fifty-five canons, twenty-two principles, thirteen postulates, and ten devices (Indian Statistical Institute 2012, 34-38). Semantic and syntactic relations are enshrined in his order of main classes, Principles of Helpful Sequence in arrays, the PMEST facet formula fitted with rounds and levels of facets, and other principles, such as the famous wall-picture principle for citation order of facets, and numerous devices for improvising class numbers for non-existent isolates and potential subjects. Briefly explained are facet and phase analyses and number building with its notational base of seventy-four characters and symbols. The entry concludes with a discussion of the extent of application of CC in libraries, its contribution to the science of classification, and a view of its future.
