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

Expanded hours of access and the reduction of peak system loads are often cited as advantages of remote access to OPACs. This argument is based on the assumption that remote users search OPACs when libraries are closed or when there is low internal use. The study tested this assumption by performing a transactional log analysis of the remote and internal use of the OPAC at the Research Libraries of the New York Public Library. Analysis showed that pateerns of remote and internal use differed greatly. A large part of the remote searching occured when the Research Libraries were closed. Compared to internal searching, remote searching was distributed more evenly over the course of the day and the week. Results show that remote access expands the hours of use of the Online catalogue and has potential to reduce peak system loads at the Research Libraries

Abstract: The function of the W3, like that of Z39.50, is to offer access to networked information, and they appear to have similar client/server architectures. However, libraries need both because of the W3's lack of support for the advanced search, retrieval and management facilities that are expected of modern OPACs and are offered by Z39.50. Current research is involved in developing hybrid W3/Z39.50 services

Abstract

Describes types of international gateways available for online searching. Public data networks are provided by national telecommunications authorities. Private data networks are run by an organization for its own use, or for customers of its services. Academic data networks are a special case of private networks which serve the the academic and research communications. Gives details of a number of academic networks: JANET, BITNET, NETNORTH, EARN, Internet. Describes the gateways between JANET and the UK public data network, EARN and Internet. Describes the international X.25 infrastructure (IXI) network which is organized by COSINE (Cooperation for OSI networking in Europe) programme which aims to provide OSI-based services for European researchers

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

Discusses Austrian government policy on the information superhighway (ISH) since Aug. 94. The Austrian telecommunications infrastructure is far behind the standards of Europe. The Austrain PTT monopoly over the public telecommunications network is an obstacle to development. The rates for data services are still based on copper cable with transmission speeds of 9600 Kbps. Although there are various ISH initiatives in Austria, the gap between vision and reality is large. Describes the initiatives of the Austrian National Host and the Bureau for International Research and Technology Cooperation; the Austrian Platform for Telematic Applications; BNet (Burgenland); Telematik Initiative Wien; TELKIS Telekommunikationsinitiative Steiermark; Datahighway Upper Austria; Vorarlberger Telekommunikations GmbH; Telematik Initiative; Datenbahn Telecom GmbH (Salzburg); Ti-KOM (Tirol) and other initiatives

Abstract

The Z39.50 standard for information retrieval is important from a number of perspectives. While still not widely known within the computer networking community, it is a mature standard that represents the culmination of two decades of thinking and debate about how information retrieval functions can be modeled, standardized, and implemented in a distributed systems environment. And - importantly -- it has been tested through substantial deployment experience. Z39.50 is one of the few examples we have to date of a protocol that actually goes beyond codifying mechanism and moves into the area of standardizing shared semantic knowledge. The extent to which this should be a goal of the protocol has been an ongoing source of controversy and tension within the developer community, and differing views on this issue can be seen both in the standard itself and the way that it is used in practice. Given the growing emphasis on issues such as "semantic interoperability" as part of the research agenda for digital libraries (see Clifford A. Lynch and Hector Garcia-Molina. Interoperability, Scaling, and the Digital Libraries Research Agenda, Report on the May 18-19, 1995 IITA Libraries Workshop, <http://www- diglib.stanford.edu/diglib/pub/reports/iita-dlw/main.html>), the insights gained by the Z39.50 community into the complex interactions among various definitions of semantics and interoperability are particularly relevant. The development process for the Z39.50 standard is also of interest in its own right. Its history, dating back to the 1970s, spans a period that saw the eclipse of formal standards-making agencies by groups such as the Internet Engineering Task Force (IETF) and informal standards development consortia. Moreover, in order to achieve meaningful implementation, Z39.50 had to move beyond its origins in the OSI debacle of the 1980s. Z39.50 has also been, to some extent, a victim of its own success -- or at least promise. Recent versions of the standard are highly extensible, and the consensus process of standards development has made it hospitable to an ever-growing set of new communities and requirements. As this process of extension has proceeded, it has become ever less clear what the appropriate scope and boundaries of the protocol should be, and what expectations one should have of practical interoperability among implementations of the standard. Z39.50 thus offers an excellent case study of the problems involved in managing the evolution of a standard over time. It may well offer useful lessons for the future of other standards such as HTTP and HTML, which seem to be facing some of the same issues.
