UDC Online




The UDC Online is the Complete Edition of UDC with additional functionality. Originally intended for organizing documentation on everything that had ever been written, UDC has exceeded its parent, the Dewey Decimal Classification, both in the size of its vocabulary and its indexing capabilities.

It was produced and researched in association and with representation from the following industry experts:

  • CILIP (Chartered Institution of Library and Information Professionals)
  • National Information Services and Systems (NISS)
  • Society of Indexers
  • Standing Conference of National and University Libraries.

Derived from the Master Reference File (MRF) from the UDC Consortium, UDC Online contains all available references and classification and has over 65,000 entries.

UDC Online has been given a complete overhaul by BSI and is now owned and run by us.
