Abstract
Examines ho well UDC numbers performs as a subject retrieval device in online systems. Discusses: truncation, coordination, USC as a discipline based scheme, ranges, and requirements in search software. Gives examples of UDC in pre-coordinated and post-coordinated working systems. Discusses the possible use of UDC as a thesaurus. Outlines improvements that would enable its use in online retrieval
