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

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

The focus of this study is the search behavior of remote users of the University of California MELVYL Library System, an OPAC. Transaction logs from randomly selected remote user search sessions are analyzed. Descriptive data on the number and type of searches, choice of search mode and database, number of retrievals, number and type of errors, and use of system HELP facilities are presented. The search data have been cross-tabulated with demographic data on the same group of remote users, collected through an online survey conducted by the authors. Effectiveness of system usage is discussed. A case mode is made for the desirability of additional heuristics in the catalog portion of the system

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

Discusses the advantages and disadvantages of a common user interface to enable searching of all databases regardless of producer, supplier or location, such as local CD-ROM, or network. Explains client server architecture, the basic component of a common user interface and outlines current developments including the Z39.50 application layer protocol. A common user interface will result in greater synergy between information providers, technology providers, distributors and information professionals. It will also be able to search across the Internet and make that huge wealth of data much more available than it currently is. Predicts that a common user interface will be in operation by the turn of the century

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

Hinich and Molyneux review the literature of internet measurement and note three results consistently to be found in network traffic studies. These are "self-similarity," "long-range dependence," by which is meant that events in one time are correlated with events in a previous time and remain so through longer time periods than expected, and "heavy tails" by which they mean many small connections with low byte counts and a few long connections with large byte counts. The literature also suggests that conventional time series analysis is not helpful for network analysis. Using a single day's traffic at the Berkeley National Labs web server, cumulated TCP flows were collected, log transforms were used with the adding of .01 to all values allowing log transforms of the zero values, and providing a distribution that overcomes the heavy tail problem. However, Hinich's bicorrelation test for nonlinearity using overlapping moving windows found strong evidence of nonlinear structures. Time series analysis assumes linear systems theory and thus additivity and scalability. Spectral analysis should provide large peaks at the lowest frequencies if long range dependence is present since the power spectrum would go to infinity if the frequency goes to zero. This does not occur and so long range dependence must be questioned, at least until it is determined what effect other OSI layers may have on the TCP data.
