    Abstract
    The ANSI Z39.50 standard was adopted 10 years ago. It outlines a set of rules and procedures to allow a computer system to search the databases provided by another system and to retrieve the results of that search. Traces its development adoption in library automation product lines. Recent major developments have been the migration to version 3 and the adoption of community profiles. Community profiles are documents that describe agreements that a community of interest develops to ensure clients and servers can interpret in specific ways.

    Abstract
    Describes the development of SuperJANET, the new optical fibre network for the UK academic and research community. Considers pilot applications for SuperJANET covering library and non library applications and strategic issues to be met for SuperJANET to become an information superhighway. Gigabyte networks will be 1.000 time faster than JANET and will enable sophisticated image and voice communication. SuperJANET uses synchronous digital hierarchy technology. SuperJANET is being developed and and introduced in a number of phases. Discusses supercomputing, library and information services, and strategic issues. Examines the role of technology and librarians in the development of the virtual library

    Abstract
    In Sept. 1990, the US Dept. of Education's Library Technology and Cooperation Grants Program awarded a three-year grant to the Florida Center for Library Automation (FCLA), an agency of the Florida State University System, to develop software adhering to the ANSI Z39.50 Information Retrieval protocol standard. The Z39.50 software was to operate over the OSI communications protocols and be integrated with FCLA's NOTIS system, which is shared by all 9 state universities in Florida. In order to test the correctness of its Z39.50 software, FCLA sought out other library software developers who would be willing to develop Z39.50 systems of their own. As part of this process, FCLA helped to found the Z39.50 Implementor's Group (ZIG), which has since gone on to improve the standard and promote Z39.50 implementations throughout much of the North American library systems marketplace. Early on in the project, it became apparent that TCP/IP would be a more heavily used communication vehicle for Z39.50 messages than OSI. FCLA expanded its design to include TCP/IP and, by the end of the grant in Sept. 1993, will have a working Z39.50 system that can communicate over both OSI and TCP/IP networks

    Abstract
    The primary objective of the present study was to exmine whether readers conducting bibliographic searches in ALEPH - Israel's research library network - tend to search only within the OPAC of the library within which they are working or whether they access the remote OPACs of other libraries. The ALEPH network has a dezentralized database. Therefore, it was possible to examine this question because each library has its own access code and each database can be searched separately. The data were collected by means of a one-page questionnaire lefr beside each terminal in the library of the Graduate School of Library and Archive Studies of the Hebrew University of Jerusalem during an entire academic years. results of analysis of the data collected in this survey are presented in 6 tables

    Abstract
    Information retrieval (IR) protocols support effective and interoperable intersystem search and retrieval. Although intersystem search methods have been envisioned and under development since the 1970s, it was the Z39.50 IR protocol, first released in 1988, that demonstrated real-world possibilities for such search and retrieval. As the networked information environment changed with the emergence of the World Wide Web, the need for standard IR protocols did not disappear, and one can argue the need is even more compelling given both the visible and invisible Web. A new protocol, based on the experience from Z39.50 but simpler and more comprehensible than Z39.50, is now being used for Web search and retrieval. Search and retrieve via URL (SRU) uses Web technologies and standards resulting in a Web friendly protocol that provides standard search access to existing Z39.50 resources and a wide-range of new non-catalog digital resources. This entry provides both an overview of the two protocols and technical details to understand both. A brief discussion of IR and communications protocols provides background to the specifics of these two IR protocols. Although communication protocols are by their nature technical specifications, this entry focuses on an overview of the functions and capabilities of the protocols. It uses technical concepts and terminology from the protocols to help explain how the protocols work but limits discussion of technical details.

    Abstract
    Networks allow different users from outside the library to have remote access to library catalogues. These remote users may face problems that differ from the OPAC users' in the library. They may not be comfortable with the computer technology and may not be familiar with the OPAC of the library. Libraries should offer different support services from those provided to on-site users. These users need technical advice as well as special instruction aids and guides to lead them to the information they want to retrieve
