Abstract
Examines the use of the Z39.50 Information Retrieval protocol for provision of access to its collections. Z39.50 offers a translation of different search engines developed by library systems suppliers and online database hosts. Traces its development and describes its abstraction and metalanguage, and the TCP/IP and OSI layer. It is being further developed in project ONE - OPAC Network in Europe, and European Union Library Plan project which began in Jan 95, of which the British Library is a partner. It aims to link national library catalogues in an open standards and telecommunications network, and to achieve interoperability by use of Z39.50. Describes the project so far, agreements made, and future developments
