- Abstract
- Describes the backgroud to the construction of a thesaurus at Hydro-Quebec, Quebec, Canada. Several information units, linked to form a network, share the same bibliographic database. The need for coherence and efficiency was the principle motive for the construction of the multidisciplinary thesaurus. Describes the construction process, discusses the specifity of the tool, its circulation, and considers its use on a partnership basis with other information services

- Abstract
- The aims of CATRIONA were: (1) to investigate the requirements for developing procedures and applications for cataloguing and retrieval of networked resources, and (2) to explore the feasibility of a collaborative project to develop such applications and procedures and integrate them with existing library systems. The project established that a distributed catalogue of networked resources integrated with standard Z39.50 library system OPAC interfaces with information on hard-copy resources is already a practical proposition at a basic level. At least one Z39.50 OPAC client can search remote Z39.50 OPACs, retrieve USMARC records with URLs in 856$u, load a viewer like Netscape, and use it to retrieve and display the remotely held electronic resource on the local workstation. A follow-up project on related issues is being finalised.

- This article discusses the emergence of distributed library services drawing on recent European initiatives to describe developments. It focuses on Z39.50-based services. It outlines a descriptive framework for such services and briefly introduces developments in other domains. Projects funded through the EU Telematics Application Programme are highlighted and some recent developments in U.K. higher education are introduced

- Abstract
- OPAC Network in Europe (ONE) is a project aimed at providing users with better ways to access library OPACs and national catalogues and which will stimulate and facilitate internetworking between libraries in Europe. The project is based on SR/Z39.50 standards which enable users to search widely different computer systems across networks and offer end users the promise of greater ease of use through a solution to the proliferation of different user interfaces to library catalogues

- Abstract
- The Nordic SR-net project started in 1991, with the aim to develop communications between university library systems and union catalogues in all five Nordic countries, based on the ISO protocol Search and Retrieve. The plan was to develop totally integrated solutions, where the use interface of the remote systems would be hidden, and users can use their own interfaces from their own home systems

- Abstract
- Reports on the work of the ABDUX project to investigate the use of the standardized protocol for the X.500 directory service for searching distributed bibliographic databases. It is a joint project between the Computer Science Department of the University College London, and the Library and Computer Service of Brunel University, UK. Gives a design overview and discusses the implementation phase of the project which involved: enhancements to an X.500 system; implementing user interfaces; and gathering test data for the system. Examines experiences with the system, and assesses why interest in the system has been less than hoped for. Puts forward a model for bibliographic querying which recognises the role of other protocols. Summarizes the main lessons to be drawn from the project

- Abstract
- During the 1990s statewide cooperative use of networks in the USA has moved towards providing mainly access to bibliographic and full-text resources not held locally and usually provided by commercial vendors for use by libraries. Describes 3 academic library networks: the University System of Maryland's Library Information Management System serving the information needs of users throughout the state; Georgia's GALILEO (Georgia Library Learning On-Line) which provides a set of electronic resources and services for the 34 colleges and universities of the University System of Georgia; and TexShare in which all 52 libraries from the public educational institutions in Texas participate. Although the development of funding sources, the technical implementations and support, and the management organization differ from state to state, all three reflect an incremental shift towards the electronic library

- Abstract
- This article describes an approach for linking geographically distributed collections of metadata so that they are searchable as a single collection. We describe the infrastructure, which uses standard Internet protocols such as the Lightweight Directory Access Protocol (LDAP) and the Common Indexing Protocol (CIP), to distribute queries, return results, and exchange index information. We discuss the advantages of using linked collections of authoritative metadata as an alternative to using a keyword indexing search-engine for resource discovery. We examine other architectures that use metadata for resource discovery, such as Dienst/NCSTRL, the AHDS HTTP/Z39.50 Gateway, and the ROADS initiative. Finally, we discuss research issues and future directions of the project. The Internet Scout Project, which is funded by the National Science Foundation and is located in the Computer Sciences Department at the University of Wisconsin-Madison, is charged with assisting the higher education community in resource discovery on the Internet. To that end, the Scout Report and subsequent subject-specific Scout Reports were developed to guide the U.S. higher education community to research-quality resources. The Scout Report Signpost utilizes the content from the Scout Reports as the basis of a metadata collection. Signpost consists of more than 2000 cataloged Internet sites using established standards such as Library of Congress subject headings and abbreviated call letters, and emerging standards such as the Dublin Core (DC). This searchable and browseable collection is free and freely accessible, as are all of the Internet Scout Project's services.
As well developed as both the Scout Reports and Signpost are, they cannot capture the wealth of high-quality content that is available on the Internet. An obvious next step toward increasing the usefulness of our own collection and its value to our customer base is to partner with other high-quality content providers who have developed similar collections and to develop a single, virtual collection. Project Isaac (working title) is the Internet Scout Project's latest resource discovery effort. Project Isaac involves the development of a research testbed that allows experimentation with protocols and algorithms for creating, maintaining, indexing and searching distributed collections of metadata. Project Isaac's infrastructure uses standard Internet protocols, such as the Lightweight Directory Access Protocol (LDAP) and the Common Indexing Protocol (CIP) to distribute queries, return results, and exchange index or centroid information. The overall goal is to support a single-search interface to geographically distributed and independently maintained metadata collections.
