    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
    Discusses the factors influencing remote access to CD-ROMs: how many CD-ROM workstations are located at the place of work (single or multiple workstations); whether a PC or a CD-ROM LAN is in operation; what level of security is needed in the organisation; how many remote users need to be accomodated; and the level of software sophistication present in the staff of the organisation

    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
    Der neue 128-Bit-Header treibt die Möglichkeiten ins Astronomische: 3,4 mal zehn hoch 38 Adressen, eine 3,4 mit 38 Nullen. -Das IPv6-Forum zerhackte den Zahlentrumm in anschauliche Stücke: Pro Quadratmillimeter Erdoberfläche stehen nun zirka 667 Billiarden, pro Mensch 6,5 mal zehn hoch 28 Adressen, bereit." Eine Billiarde bringt es immerhin auf respektable 15 Nullen. Schon kurz darauf ging ein Aufschrei durch die Netzgemeinde. Das neue Protokoll schrieb die weltweit eindeutigen Seriennummern bestimmter Netzwerkkarten auf den virtuellen Adressaufkleber. Die Ethernet-Adapter bewerkstelligen den Datentransport bei Computern, die über eine Standleitung, ein Koaxialkabel, dauernd online sind. Die Spur von Ethernet-Usern wäre damit leicht zu verfolgen gewesen, ihre Nutzerprofile, ihre Surfgewohnheiten einsehbar wie offene Bücher. Das Problem, ließ Icann nun wissen, sei behoben: Es gebe keine festen Kennzahlen mehr in den Adressköpfen. Bei jedem Hochfahren eines Rechners oder sogar noch öfter werden die Nummern neu durchgemischt", erläutert Hans Petter Dittler, stellvertretender Vorsitzender der deutschen Sektion der Internet Society. Das Betriebssystem Linux kann bereits mit dem IPv6 arbeiten. Microsoft will den Standard in das nächste Windows-Betriebssystem einbauen: "Wir denken, der vorgeschlagene Standard ist wichtig zum Schutz der Privatsphäre der Internet-Nutzer", sagt Jawad Khaki, Vizepräsident für Netzwerke. Seit einigen Tagen steht auf der Microsoft-Homepage eine Vorab-Version von lPv6 für Windows 2000 zum Herunterladen bereit. Geradezu euphorisch gibt sich Protokoll-Chef Vint Cerf. Mit IPv6 haben wir die Grundlage dafür", philosophierte der Internet-Daddy auf dem ersten lPv6-Kongress 1999 in Berlin, "das Internet von unserem Planeten über den Mars und die Asteroiden bis in den Weltraum hinaus auszudehnen." Doch im Internet-Alltag wird das alte Protokoll noch lange Vorrang haben. Grund sind handfeste Programmier-Probleme. Denn Software, die sich explizit auf die vierte IP-Version bezieht, muss umgeschrieben werden - etwa um mit den längeren Adressfeldern umgehen zu können. Hubert Martens vom Münchner Multinet Services befürchtet gar einen InternetCrash: "Das Jahr-2000-Problem war harmlos gegen das, was uns mit lPv6 droht."
