Title: Gemeenschappelijke onderwerpsontsluiting (GOO) : een samenwerkingsproject in Pica-verband
Source: Open. 24(1992) no.2, S.48-53
Year: 1992
Abstract: In the Netherlands, for historical reasons, there have been wide variations in subject indexing practice from library to library. With the creation of the Pica (Project for Integrated Catalogue Automation) catalogue network a start was made to create a subject classification suitable for all types of libraries. In 1985 a working party was formed with representatives from the Dutch university libraries and Royal Library. The working party has been responsible for the creation of the general subject classification which has been in use in the Royal Library, and Groningen, Leiden, Nijmegen, and Twente university libraries since Oct. 91. The system was designed for use in online public access catalogues but may also be used as a basis for collection assessment
