    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 IOS rererence model of open distributed processing (RM-ODP) consists of: an overview of the reference model, the descriptive model, the prescriptive model, and the architectural semantics. They provide the concepts and rules of distributed processing to ensure openness between interacting distributed application components. Openness is a combination of characteristics: accessibility, heterogeneity, autonomy and distribution. The RM-ODP introduces the concept of viewpoint to describe a system from a particular set of concerns, and hence to deal with the complexity of distributed systems. While all the viewpoints are relevant to the description and design of distributed systems, the computational and engineering models are the ones that bear most directly on the design and implementation of distributed systems. From a distributes software engineering point of view, the computational and engineering viewpoints are again the most important; they reflect the software structure of the distributed application most closely. Concentrates on the computational and engineering viewpoints

    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
    CD-ROM databases are finding a permanent niche in libraries and librarians are trained both to use each new product and to keep abreast of changes in them. From the library user point of view it is possible to dial into or remotely access CD-ROM databases. Discusses the use of the communications software pcAnywhere, examines the benefits to users and libraries of remote access, and lists other areas which might be of interest to learning resource centres in regard to CD-ROM services

    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

    Open System Interconnection (OSI) Standard 7498 appeared in 1984. Open systems of PCs and workstations decentralize information processing and divide it between several computers, based on the client-server concept. Relevant terminology is explained, including application protocol, bases of the SR/Z39.50 model, data transmission, search request services, query types, attribute sets, transmission format, transfer syntax, solution models and cooperation between library systems

    Abstract
    Hartford University mounted a DRA Atlas Integrated library system in 1991, using a DECnet/Ethernet network and a VAX 6310 mainframe computer. As VAX VT320 terminals were available in many campus buildings, the library's catalogue could be searched from many locations and could be dialed up by remote users. Commercial databases in MARC format could be mounted on the system and searched with the same commands that users employed for the OPAC. Explains the use of Periodical Abstracts from UMI on the online catalogue. Discusses searching strategies and compares the Periodical Abstracts Ondisc CD-ROM with the tape loaded product

    Abstract
    Adaptive, in-call, bandwidth reservation may be used to enhance bandwidth utilization in a policed asynchronous transfer mode (ATM) virtual path shared by traffic streams originated by many bursty sources. Presents a model, based on Markov-modulated sources and stochastic fluid methods, for performance analysis of the proposed mechanism. The model, corroborated by simulations, is used to study achievable bandwidth gain and the effects of feedback delay and competing reservation processes

    Abstract
    Examined two groups of online catalogue users segregated by their method of access to the system: terminals in the library or remote workstations. An online survey collected demographic data, perceptions on source and terminal accessibility, and information on usage, task variety and search satisfaction. Transaction logs furnished data on browsing behavious, while interviews of both groups provided additional information about remote use. Results indicate that remote use is comparable to traditional use

    Abstract
    This study aimed to determine if the searching behaviour of remote users of LIAS, Penn State's online catalogue differed from those using the OPAC within the library. More than 1.000 searches done by remote users (those accessing the system via either dial-access or the university's computer network) were compared to more than 1.000 searches done by in-house users. Each search was duplicated step by step and analysed according to a pre-determined set of criteria. Although few dramatic differences were found between the 2 groups, there were enough subtle differences to generate interest. In general, remote users are the more sophisticated searchers, bearing out the assumption that remote users seem to have a better conceptual knowledge of how an information system should operate. On the other hand, they struggle more with the procedural details of how to use the OPAC. Dial-access users seem to constitute a unique group of users: their searches are often quite different than those done by either network or in-house users

    Abstract
    The rapid growth of the Internet TCP/IP networks has encouraged the deployment of management products based on the Internet's Simple Network Management Protocol (SNMP). However, many organizations, including most telecommunications service providers, continue to define enterprise management solutions based on ISO/CCITT standard management and underlying Common Management Information Protocol (CMIP). Concludes that the key to achieving timely, effective, integrated management is to encourage a transition process aimed away from existing commercial investment in both ISO/CCITT and Internet based management technologies through deployment of common methods and tools which support integration
