Reflections on the utilization of the Universal Decimal Classification

Until recently the writer participated actively in the application and development of the Universal Decimal Classification, principally by means of computer‐based techniques available via large ICL 1900 series installations. During the decade 1968–1978 a multi‐purpose database was developed and operated using remote computer resources equipped with extensive telecommunication facilities. Primarily designed to support senior managers, the subject coverage of the system encompasses all matters judged to be useful in the particular business environment concerned. One feature of the system is the use of the UDC for both information (reference) retrieval and profile matching. It is hoped that some personal reflections arising from the experience gained and on associated matters will be useful to those involved in the management of information in large organizations.
