Title
¬De ontwikkeling van het onderwerpsontsluitingssysteem t.b.v. de Nederlandse Bibliografie

Abstract
In May 80 the joint working parties on the Dutch National Bibliography and the Dutch National Bibliographical Centre published their final report containing proposals for a national bibliography in the Netherlands based on Brinkmann's catalogue of books. In view of the limited number of terms used in the subject index of Brinkmann's catalogue it was proposed to adopt the thesaurus of headings developed by the Netherlands Bibliotheek en Lektuur Centrum with the addition of UDC and SISO classification numbers to each entry. A test-run has identified a core of some 3.500 headings which will be input into the database to provide a subject index to the bibliography. The system will become operational on 1 Jan 81
