Abstract

A survey is given, how modifications in the field of the information processing and technology have influenced the concepts for teaching and studying the subjects of knowledge organization and information retrieval in German universities for library and information science. The discussion will distinguish between fields of modifications and fields of stability. The fields of the modifications are characterised by procedures and applications in libraries. The fields of stability are characterised by theory and methods

Abstract

The study of faceted classification systems has primarily been directed towards application for precombined catalogues or bibliographies, not so much for use in post coordinated retrieval systems. Argues that faceted classification systems in some respects are superior to other techniques of on-line retrieval as far as facet and concept analysis is combined with an expressive notational system in order to guide a form of retrieval which will use Boolean operators (for combining the facets regardless of one special citation order) and truncation for retrieving hierarchically different sets of documents. This point of view is demonstrated by 2 examples. The 1st one uses a short classification system derived from B. Buchanan and the 2nd is built upon the classification system used by Library and Information Science Abstracts (LISA). Further discussion is concerned with some possible consequences which could be derived from a retrieval with PRECIS strings
