Indian librarian and educator (mathematician) who was considered the father of library science in India and whose contributions had worldwide influence.
Ranganathan's chief technical contributions to library science were in classification and indexing theory. His Colon Classification (1933) introduced a system that is widely used in research libraries around the world and that has affected the evolution of such older systems as the Dewey Decimal Classification. Later he devised the technique of chain indexing for deriving subject-index entries.
His Five Laws of Library Science (1931) was widely accepted as a definitive statement of the ideal of library service. He also drafted plans for a national and several state library systems, founded and edited several journals, and was active in numerous professional associations.
Colon Classification is the system of library organization developed by Ranganathan in 1933. It is general rather than specific in nature, and it can create complex or new categories through the use of facets, or colons.
In it, there are 108 main classes and 10 generalized classes (broadly divided between the humanities and sciences), which are represented by a mixed notation of Arabic numerals and Roman and Greek letters. Each main class comprises five fundamental facets, or groups: personality, matter, energy, space, and time.
Ranganathan's main contribution to classification was the notion of these fundamental facets, or categories. Instead of schedules of numbers for each topic, Colon Classification uses series of short tables from which component numbers are chosen and linked by colons to form a whole. The book number is an integral part of the call number, a departure from Dewey or Library of Congress systems.
Each main class has its appropriate facets and focuses; e.g., literature has language and form. In addition, there are four floating tables that correspond to subdivisions -- e.g., form, geography, time, and language. Further expansion of the tables is allowed through colon addition or omission (if the subject cannot be expanded).
The collection of the University of Madras, India, was utilized in the creation of Colon Classification.
