Abstract

Reflects on the situation a few years ago in the field of subject access in libraries and evaluates the present situation in the light of recent developments. Discusses factors which characterise the situation in West Germany today. Examines the organisation of cooperative subject access during the course of which various relationships are explored, and the dovetailing of the network and local library operations, and the formation of local and on-line catalogues are discussed. Describes the relationship between formal and subject access; discusses cooperation in the allocation of catchwords, and cooperation in classified subject access; and addresses 2 forms of cooperative subject access

Abstract

The problem of the equivalence relationship in natural languages and in artificial documentary languages is discussed and it is shown that the use of this concept for synonyms should be avoided. A proposal is made to substitute this concept by similarity or tolerance relationship

Abstract

Analyses mathematical terminology to give practical hints for assigning subject headings to a book and proposes a method to use for subject analysis. The method is based on connections between the subject-classification scheme of the American Mathematical Society and indexing with subject headings. Gives examples and compares them with LCSH and PRECIS. A thesaurus of mathematics, using PRECIS methods and connecting with the Amercian Mathematical Society classification is desirable. Authors could also classify their own work and the data could be printed with the books

Abstract

Free text searching with keywords in a complete data store is not necessarily the best automatic retrieval method. There must be a proper classification of documents and concepts and the use of a proper classification system avoids problems of terminological deficiency. The dialogue search form makes the on-line catalogue a new information medium. A bibliographic unit must be created with as many search access points as possible, using verbal and classificatory search elements. Verbal search categories must include free text elements for individual search access requirements and a controlled vocabulary with syntactic connections. Classified data should consist of a universal classification system with clear structural notation for access and surface searching, together with several specialist subject classifications for differentiated documentation and retrieval. The universal classification needs no detailed subdivision: it serves mainly as a guide and entry to the detailed sub-systems
