    Abstract
    The universal classification schemes developed in the 19th century are a direct response to the social changes of that era. However, the increasing use of automation in libraries has highlighted the need fir greater precision in hierarchical structures. A thesaurus of used and related headings can be employed to show the spatial relationship of semantic terms. The resulting search profile can be further enhanced by the addition of citation weighting. To assist users to define searches more accurately libraries using large general classification schemes should consider adding supplementary classification data to records

    Abstract
    Developments in electronic communication technology have meda online databases a normal part of library collections. To provide users with direct access to Internet resources the Dutch Royal Library has cooperated with several university libraries in the Netherlands to develop the Nederlandse Basisclassificatie Web. Subject specialists select sources, add English summaries and NBW code, and input them to the online database. A Web desk and training workshops have been provided to assist users, and improvements to the system will simplify search procedures
