    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
    Z39.50 is an information retrieval protocol. It has generated much interest but is so far little deployed in UK systems and services. Gives a functional overview of the protocol itself and the standards background, describes some European initiatives which make use of it, and outlines various issues to do with its future use and acceptance. Z39.50 is a crucial building block of future distributed information systems but it needs to be considered alongside other protocols and services to provide useful applications

    Abstract
    Proposes a new model for bibliographic access, the virtual catalogue, to serve the virtual library. Suggests the use of current software and networks to build links between bibliographic databases of all kinds, including full text, to enable the user to search a specified subset of databases. Suggests that local data be limited to holdings information linked to, but separate from, bibliographic databases both local and remote

    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.

    Abstract
    The State Library of Iowa, USA, received a Higher Education Act title II grant from the US Dept. of Education in 1994 to create a demonstration project of new library information technologies. Describes 2 interlinked components of the project: Web-based union catalogue development and statewide deployment of the ANSI/NISO Z39.50 standard for database search and retrieval. Z39.50 was chosen because of its ability to searching multiple remote databases in a single session and its common interface across a variety of implementations. Use of a distributed Z39.50 search makes the need for maintaining large union catalogues unnecessary

    Abstract
    The British Library is currently progressing several projects involving Z39.50 and SR standards. The Network OPAC trial service is being extended for a further year and the user base broadened. Future applications of Z39.50 currently being investigated include access from Z39.50 clients developed by other suppliers; a virtual database to cover all the library's diverse catalogues; and a national distributed bibliographic database

    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

    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
    Describes the virtual Canadian union catalogue (vCuc) pilot project which aims to determine the long term feasibility of using Z39.50 for searching distributed individual library catalogues and union catalogues which together would emulate a centralized union catalogue. This 'virtual' catalogue will not replace the existing union catalogue at the National Library of Canada, but rather complement it. Describes progress to data with the project

    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.

    Abstract
    Effective resourcesharing presupposes an infrastructure which permits users to locate materials of interest in both print and electronic formats. 2 approaches for providing this are union catalogues and Z39.50 based distributed search systems and computer to computer information retrieval protocols. The advantages and limitations of each approach are considered, paying particular attention to a relaistic assessment of Z39.50 implementations. Argues that the union catalogue is far from obsolete and the 2 approaches should be considered complementary rather than competitive. Technologies to create links between the bibliographic apparatus of catalogues and abstracting and indexing databases and primary content in electronic form, such as the new Serial Item and Contribution Identifier (SICI) standard are also discussed as key elements in the infrastructure to support resource sharing
