Abstract

Retrieval techniques may be based on the full text of documents, or on descriptors selected from a thesaurus. The latter approach constitutes an attempt to bridge the gap between demand and documents, which causes problems if demand cannot be forecast. Building up a thesaurus involves choosing the method of collecting descriptors, choosing the actual descriptors and making the system easily accessible to users. Classification and a classified catalogue are essential to the organisation of knowledge. Rules for the formation of classes have developed out of natural systems of classification. Chain indexing greatly aids the formation of the subject index. UDC and DDC are used in most documentation centres in the Netherlands. Public libraries mostly use SISO, a Dutch universal classification system
