📚 Classified Catalogue Code (CCC) by S. R. Ranganathan – A Fundamental Cataloguing Standard in Library Science



The Classified Catalogue Code (CCC) is a pioneering Indian cataloguing code developed by Dr. S. R. Ranganathan in 1934. It is designed to work with the Colon Classification System and provides structured rules for cataloguing books in a subject-wise, classified format.

  • Multiple Access Points: Main, author, class, and analytical entries.
  • Cross References: Provides detailed access through see/see also references.
