025.0 Library systems: Z39.50

025.0 Bath Profile: International Z39.50 Specification for Library Applications and Resource Discovery Draft profile identifying a subset of specifications from the Z39.50 Information Retrieval Protocol for use in Z39.50 client and server software. An explanation is given as to how this will improve search and retrieval among library catalogues, union catalogues, and other electronic resource discovery services worldwide, together with information about scope, functional requirements, and conformance issues.


025.04 BookWhere Searchable Databases List of hundreds of library catalogues and other information databases that can be searched using the Z39.50 protocol using BookWhere software, which has a pre-configured list of available hosts and databases. Includes a virtual demonstration of the software.


025.04 BOPAC2: Bradford OPAC 2 A project aimed at dealing with the problems of large and complex retrieval sets, possible from multiple databases, obtained via the Z39.50 protocol. The trial service allows cross-searching of at least 12 university library catalogues, using Z39.50 from within a Web browser.


025.0 Directory of Z39.50 Targets in the UK Directory service which provides information about Z39.50 targets in the UK in order to support the configuration of Z39.50 clients and facilitate connection to UK services. It allows UK organisations with Z39.50 targets to register these services, describe connection parameters and document supported search attributes.


025.04 Distributed Searching Across Cultural Resources Using Z39.50 and SQL: A Powerful Combination Conference paper (January 1999) which promotes a standards-based approach to Web-enabled inter-operable information retrieval for cultural networks (such as museums and galleries), using Z39.50 and the associated CIMI (Consortium for Interchange of Museum Information) profile. It presents Z+SQL, the adaptation of the Z39.50 protocol to the SQL domain. By uniting the advantages of the SQL query language with the information retrieval services of Z39.50, Z+SQL presents SQL-enabled cultural communities with a possible solution to their future distributed querying needs, to help facilitate access to their resources.


025.0 Issues Related to the Use of Z39.50 to Emulate a Centralized Union Catalogue A discussion project conducted in 1997 which arose out of the virtual Canadian union catalogue project. Deals with technical, vendor, bibliographic data, and administrative issues.


025.04 Library of Congress WWW / Z39.50 Gateway Links to various Z39.50 resources that relate to searching databases that have implemented Z39.50. Access to many Z39.50 servers is provided through the LC’s WWW/Z39.50 gateway.


025.0 MODELS: Moving to Distributed Environments for Library Services The MODELS project involves the examination of metadata and the collections they describe. Metadata and collections currently reside in multiple disjointed print and digital resource spaces. MODELS seeks to explain and analyse some of the issues involved in reducing this disjointedness and moving towards more unified access to information systems and resources.


025.0 Profile for Z39.50 over HTTP Discussion paper aimed towards a profile for Z39.50 over HTTP, covering five main issues: Encoding (ASN.1/BER v. character encoding), Statefulness and statelessness, Z39.50 state machine peculiarities,.Transport mechanism: Z39.50 over HTTP, and.Query language or protocol.


025.04 Z39.50 Application Issues Includes details of issues identified by end users who are using Z39.50.


025.04 Z39.50 Attribute Architecture Document outlining the Z39.50 attribute architecture, including revisions based on discussions at ZIG meetings (Z39.50 Implementors Group) and over the ZIG mailing list, from 1996 onwards. The major conclusion of the group was that a new architecture for attribute sets should be developed; they went on to recommend an architecture based on classes of attribute sets, with expanded attribute types.


025.0 Z39.50 Part 1: An Overview Technical briefing explaining the substance and significance of Z39.50, the international standard for communication between library and information related computer systems. Aimed at library and information system managers.


025.0 Z39.50 Part 2: Technical Details Article which describes the different facilities of Z39.50. It aims to equip librarians with enough knowledge to understand what is possible so that they can manage the set-up of Z39.50 servers or talk to vendors about their product’s capabilities.


025.04 Z39.50 Related Issues Collection of documents relating to Z39.50 including the Z39.50 information retrieval standard in English and French.


025.0 Z39.50: A Primer on the Protocol An overview of the Z39.50 standard explaining what it is and how it works. Identifies the benefits of using Z39.50 implementations, offers a brief history, describes some key technical features, provides examples of some Z39.50 applications, and forecasts the future direction of the standard. Available in PDF only.


025.04 Z39.50-International Standard Maintenance Agency This page contains documentation and information relating to the Z39.50 protocol. Various versions of the standard are provided as well as related developments. Information about the US Implementors Group (ZIG) is given, together with articles and tutorials.
