    Abstract
    Classification numbers and shelf marks may be useful in online searching. Ways of using classification in online searching include: direct classification searching; use of classification as linking devices or pivots; and direct or indirect searching of classification schedules and indexes. Discusses each of these techniques, mainly in the context of library OPAC searching although they may be applied to other types of online retrieval systems. The use of classification numbers as pivots enabling online searchers to retrieve related references by means of automation searching of identical or related classification numbers is reviewed with reference to the OKAPI project; BLCMP project and the DDC online project

    Abstract
    Discusses some of the methods of subject access to on-line catalohues (OPACs) and argues that none are entirley satisfactory. Describes 2 methods for improving subject access: best match searching; and automatic query expansion application and discusses their feasibility. Mentions emerging application standards for information retrieval and concludes that existing standards are incompatible with most methods for improving standards
