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.

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
