    Abstract
    Looks at the services offered by academic OPACs. Describes the services provided by Harvard Online Library Information System, University of California MELVYL Catalog, Stanford University' SOCRATES, and Princeton University Library. Many libraries now offer dial-up and/or Internet access to their OPACs

    Abstract
    Describes a layer model for networks. For each layer, one or more services are defined, and for each service a protocol is specified. 2 OSI application level protocols have been defined for library services: SR and ILL. The underlying layers are supposed to be OSI services, but some implementations are using TCP/IP, and some are using a mixture of OSI and TCP/IP. The systems based directly on TCP/IP can not communicate with those based purely on OSI. Discusses the pros and cons for choosing OSI or TCP/IP. Gateways between the OSI and TCP/IP networks are needed. The ISO protocol SR and the ANSI protocol Z39.50 are both 'search and retrieve' protocols. The SR is almost a subst of Z39.50, but they may become identical in the future. There is only one protocol for interlibrary loan, the ISO ILL protocol. It covers 3 models of interlibrary loan and all services connected with ILL. Other services such as Explain, Scan and Update are presently being discussed in ISO TC 46. Discusses the needs of the library community for network services such as file transfer, remote login, directories and electronic mail

    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
    Technological and regulatory developments are opening the door for competition and new services in the local loop. The reunification of Germany created an opprotunity for Deutsche Telekom to install fibre in the loop on a large scale in eastern Germany. Deutsche Telekom's strategy consists of 4 steps: fibre in the loop is seen as a process innovation. New broadband services - product innovations - can be based on the process innovation. Only a sufficient number of installations will enable the industry to invest in new products. Besides the local networks equipped with fibre, there is an overlay network for the rapid delivery of fibre access for business customers. The experience gained in eastern Germany will be transferred to western Germany when tranforming its existing network structure

    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
    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

    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
    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
    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
