Abstract
Describes the work of the ABDUX project, containing a brief description of the rationale for using X.500 for access to bibliographic information. Outlines the project's design work and a demonstration system. Reviews the standards applicable to bibliographic data and library OPACs. Highlights difficulties found when handling bibliographic data in library systems. Discusses the service requirements of OPACs for accessing bibliographic, discussing how X.500 Directory services may be used. Suggests the DIT structures that coulb be used for storing both bibliographic information and descriptions on information resources in general in the directory. Describes the way in which the model of bibliographic data is presented. Outlines the syntax of ASN.1 and how records and fields may be described in terms of X.500 object classes and attribute types. Details the mapping of MARC format into an X.500 compatible form. Provides the schema information for representing research notes and archives, not covered by MARC definitions. Examines the success in implementing the designs and loos ahead to future possibilities
