    Abstract
    Discusses the nature and importance of subject analysis and subject authority control in the retrieval tools used in libraries and information centres. Included in the discussion are the requirements for effective subject retrieval from OPACs, bibliographic databases, full text systems and the Internet. Attempts to project the nature of subject analysis systems requirements into the future and to draw some conclusions about what new information professionals should be taught, and what skills they need to acquire for application in next century

    Abstract
    Standardization of subject access to bibliographic information systems is an important factor in national and international networking, cooperation, and exchange of bibliographic data. Standards, guidelines, and rules are needed to ensure consistency and quality in the design, development and application of indexing languages to documents and their citations. This paper defines the terms "standards" and "guidelines" as they apply to subject analysis used in library catalogs and bibliographic databases. It identifies and discusses the most important national and international "standards" that influence subject access to bibliographic data. Included are the tools of subject cataloging which have become standards in their own right, as well as formally prepared and approved guidelines. Each "standard" or "guideline" is described in terms of its origins, characteristics, and control and its importance in the design of bibliographic retrieval systems. Emphasis is given to the importance of the relationship between alphabetic and systematic access.

    Abstract
    The derivation of a thesaurus from a new schedule for UDC class 61 Medical Sciences which has been restructured into a faceted classification system using the framework provided by the Bliss Bibliographic Classification. The resulting thesaurus is intended to serve as a tool for indexing and searching but will also be the index to the 61 class itself. The background for the research is briefly described. The sources and methods used to select the descriptors and define their relationships are discussed. Problems are identified and some solutions proposed

    Abstract
    This paper describes a survey of subject analysis research over the ten year period 1988 to 1998. Data are drawn from the 'research environment' encompassing publications, conference papers, major bibliographic resources in the field of Library and Information Science and selective searches of the Internet. Findings reveal major and minor areas of research activity. Trends and developments are identified and conclusions drawn. Strengths and weaknesses in the approaches taken to subject analysis research are discussed and suggestions for improvements are made with a view to future research directions
