Abstract

Academic libraries today are faced with the prospect of numerous alternatives to traditional printed indexes to the primary literature. Not only are many indexes made available by publishers on CD-ROM products, but most of these products can be acquired on computer tape for local mounting. This happy situation is further augmented by the availability of these products through mediated search services such as Dialog and end user services such as OCLC FirstSearch. Choosing the best alternative becomes a matter of estimating demand and comparing costs for each type of access. These estimates are complicated by lack of information on how often patrons will use a given alternative and by lack of qualitative data. Results of comparisons made at Trinity and Clemson Universities provide some revealing benchmarks that can help to place a quantitative framework around the decision process

Abstract

Reports a survey of all academic members of the Association of Research Libraries in the 4th quarter of 1997 which examined how academic libraries incorporate electronic information sources into their reference activities and the effects on libraries services. There was a response rate of 68 per cent, Compares results surveys carried out in 1991 and 1994. The survey covered: numbers of computers access options (intermediary, end user online, CD-ROM locally loaded databases or those accessible through the library catalogue and the Internet. There is a trend away from print resources, particularly indexing and abstracting materials, and away from CD-ROM LANs and local loading of databases towards remote online resources

Abstract

Contribution to an issue devoted on the weeding and maintenance of reference collections. CD-ROM has become part of the library universe and increasing numbers of libraries are considering the acquisition of reference tools in the new format. Issues of evaluation and selection, hardware purchase, and budget are primary concerns in this decision. Many aspects of day-to-day maintenance and access to CD-ROM sources must also be considered in the evaluation process. These issue-space, security, the care and feeding of hardware and software, reference assistance, staffing and staff training, and user instruction are vital to the success of CD-ROM in the library. Focuses particularly on literature about training for staff and users.

Abstract

Stresses the need for sites evaluating Internet resources. Lists sites and outlines how they are evaluated. Librarians need to collaborate more, and reviews need to become more consistent and informative for the user. Describes the model followed by the Marr/Kirkwood Official Guide to Business Schools Web. This uses a tabular format and compares business school sites on a set of standard criteria. The format lends itself to multiple reviewers

Abstract

A naïve user seeking introductory information on a topic may perceive a domain as it is shown by the search results in a database; however, inconsistencies in indexing can misrepresent the full picture of the domain by including irrelevant documents or omitting relevant ones, sometimes inexplicably. A bibliometric analysis was conducted on the domain of ethics in knowledge organization in the World of Science (WoS) and Library, Information Science & Technology Abstracts (LISTA) databases to discern how it is being presented by search results in those databases and to attempt to determine why inconsistencies occurred.

Abstract

We are living in a society in which using Internet is a part of everyday life. People use Internet at schools, universities, at work in small and big companies. The Web gives huge number of information from every possible field of knowledge, and one of the problems that one can face by searching through the web is the fact that this information may be written in many different languages that one does not understand. That is why web site designers came up with an idea to create on-line dictionaries to make surfing on the Web easier. The most popular are bilingual dictionaries (in Poland the most known are: LING.pl, LEKSYKA.pl, and Dict.pl), but one can find also multilingual ones (Logos.com, Lexicool.com). Nowadays, when using Internet in education becomes more and more popular, on-line dictionaries are the best supplement for a good quality work. The purpose of this paper is to present, compare and recommend the best (from the author's point of view) multilingual dictionaries that can be found on the Internet and that can serve educational purposes well.

Abstract

Describes a WWW based system which allows users to view, search and post geographically indexed information of the Earth. 2 geographic browsers have been developed: a 2D map browser capable of continuous scroll and zoom of an arbitrarily large sheet and a 3D flight-simulator browser capable of continuous flight around the Earth. On the server side, a geographical and geometrical server has been developed which contains large databases of images, elevations, lines, points and polygons stored in tiles structured into hierarchical pyramids or quadtrees. A metadata server has also been developed which contains URL pointers and geographical coordinates of various WWW documents, geographical information and geometrical models

Abstract

Hundreds of scholarly studies have investigated various aspects of Wikipedia. Although a number of literature reviews have provided overviews of this vast body of research, none has specifically focused on the readers of Wikipedia and issues concerning its readership. In this systematic literature review, we review 99 studies to synthesize current knowledge regarding the readership of Wikipedia and provide an analysis of research methods employed. The scholarly research has found that Wikipedia is popular not only for lighter topics such as entertainment but also for more serious topics such as health and legal information. Scholars, librarians, and students are common users, and Wikipedia provides a unique opportunity for educating students in digital literacy. We conclude with a summary of key findings, implications for researchers, and implications for the Wikipedia community.

Abstract

'Quality-controlled subject gateways' are Internet services which apply a rich set of quality measures to support systematic resource discovery. Considerable manual effort is used to secure a selection of resources which meet quality criteria and to display a rich description of these resources with standards-based metadata. Regular checking and updating ensure good collection management. A main goal is to provide a high quality of subject access through indexing resources using controlled vocabularies and by offering a deep classification structure for advanced searching and browsing. This article provides an initial empirical overview of existing services of this kind, their approaches and technologies, based on proposed working definitions and typologies of subject gateways

Das leidige Problem: Die Programme von Premiere World sind über den iesy-Dekoder nicht zu empfangen. Umgekehrt können die hessischen Premiere-Abonnenten mit ihrer d-box die iesy-Angebote nicht sehen. Denn statt des umstrittenen Digitalkastens aus München hat sich eKabel für eine Settop-Box des US-Herstellers Motorola entschieden. Sie arbeitet mit einer Software des amerikanischen Unternehmens Liberate und entschlüsselt alle Digitaldienste mit dem Motorola-System MediaCipher. Wer iesy-TV und die Premiere Aboprogramme der Münchner Kirch-Gruppe empfangen will, müsste sich also zwei digitale Empfangsgeräte anschaffen - eine für den Zuschauer missliche Situation. "Mit der Einspeisung der Premiere-Programme in unsere Netze verdienen wir fast nichts. Gespräche mit Kirch über ein neues Geschäftsmodell waren aber bisher erfolglos. Außerdem holt die d-box das Internet nicht auf den Fernsehschirm", begründet Geschäftsführer Günter Maier das Vorgehen von eKabel. Kirch-Sprecher Hartmut Schultz erklärt zu dem Thema lapidar, es gebe zwar Kontakte zu allen Kabelgesellschaften, aber noch keine konkreten Geschäftsmodelle". Obwohl die Kirch-Gruppe kürzlich angedeutet hatte, ihre Pay-TV-Pakete demnächst auch über andere Digitaldekoder als die d-box zu vermarkten, scheint das zumindest in Hessen noch in weiter Ferne zu liegen. Doch was bietet eKabel seinen Kunden? Zunächst ein Basispaker mit 33 analogen Fernsehprogrammen und 40 Radiosendern Die dafür zu entrichtende Kabelgrundgebühr schwankt in Hessen zwischen 15,60 Mark und 26,90 Mark. Neu ist das digitale Paket Basis plus, das Kunden für 19,60 Mark im Monat extra abonnieren können. Für sein Geld erhält der Zuschauer eine Settop-Box ins Haus gestellt, die an den Fernseher angeschlossen wird und die technische Voraussetzung für den Empfang von Digitaldiensten schafft. Mit dem Dekoder können im Basis plusPaket zehn neue digitale Spartenkanäle empfangen werden. Dabei handelt es sich um Special-interest-Sender wie Eurosportnews (Sportnachrichten), Wine & Dine (Gastronomie), Leonardo (Wissen) oder Marco Polo (Reise). Eine elektronische Programmzeitschrift, im Branchenjargon EPG - Electronic Program Guide. genannt - liefert auf Knopfdruck eine Ubersicht der neuen Programminhalte am Bildschirm. Vor allem ermöglicht die digitale Box das Versenden von E-Mails und das Abrufen von ausgewählten Internetseiten auf dem Fernsehgerät. Hierfür stellt eKabel Nutzern ein drahtloses Keyboard zur Verfügung, mit dem Webadressen und Texte der elektronischen Post eingegeben werden können. Im Basis plus-Tarif istjeweils eine Mailadresse pro Familienmitglied enthalten. Demnächst soll auch der elektronische Einkauf ("Homeshopping") am Fernseher Realität werden; insgesamt fünf Shoppingkanäle werden Zuschauern dann ihre Produkte zur Direktbestellung anpreisen. Laut eKabel-Geschäftsführer Maier ist das nur der erste Schritt zum weiteren Ausbau der iesy-TV-Angebote. Zusätzliche Digitalsender - darunter auch Spezialbouquets für ausländische Zuschauer - werden die Basispakete ergänzen, in einigen Monate sollen das Abonnement einzelner Kanäle (Pay-per-channel) sowie das Bestellen einzelner Spielfilme (Video on Demand) möglich werden. Auch für einen Hochgeschwindigkeitszugang ins Internet für den PC via Modem (iesy Net) sowie die Möglichkeit, über das Kabelnetz preiswert zu telefonieren (iesy Phone), will das Untemehmen so rasch wie möglich eine große Zahl von Kunden begeistern. Allerdings wird es rund vier Jahre dauern, bis die neuen Multimediadienste im gesamten Netz verfügbar sein werden, an dem heute 1,3 Millionen der 2,7 Millionen hessischen Haushalte hängen. Um die Strippen technisch aufzurüsten, will eKabel, das von dem britischen Telekom-Untemehmen National Transcommunications Limited (NTL) kontrolliert wird, 1,8 Milliarden Mark investieren. Langfristig will das Unternehmen 40 Prozent des Umsatzes mit Fernsehangeboten, etwa 30 Prozent mit Kabeltelefonie und ebenso viel mit Intemetdiensten und Geschäftskunden erwirtschaften. eKabel hatte vor einem Jahr 65 Prozent der zuvor im Alleinbesitz der Deutschen Telekom befindlichen Kabelanlagen erworben und dafür nach Schätzungen zwischen zwei und drei Milliarden Mark bezahlt.

Abstract

This study examines the differences between Scopus and Web of Science in the citation counting, citation ranking, and h-index of 22 top human-computer interaction (HCI) researchers from EQUATOR - a large British Interdisciplinary Research Collaboration project. Results indicate that Scopus provides significantly more coverage of HCI literature than Web of Science, primarily due to coverage of relevant ACM and IEEE peer-reviewed conference proceedings. No significant differences exist between the two databases if citations in journals only are compared. Although broader coverage of the literature does not significantly alter the relative citation ranking of individual researchers, Scopus helps distinguish between the researchers in a more nuanced fashion than Web of Science in both citation counting and h-index. Scopus also generates significantly different maps of citation networks of individual scholars than those generated by Web of Science. The study also presents a comparison of h-index scores based on Google Scholar with those based on the union of Scopus and Web of Science. The study concludes that Scopus can be used as a sole data source for citation-based research and evaluation in HCI, especially when citations in conference proceedings are sought, and that researchers should manually calculate h scores instead of relying on system calculations.

Abstract

One of the problems in assessing the success of a local library in meeting the needs of a local community has been that of visualising where its readers live. The library data file listing borrowers will have as one of its items the borrower's address and in smaller communities the librarian may have some idea as to whether or not demand for the library's services were evenly distributed. In larger communities this would be more difficult. This paper describes the use of a geographic information system to use the addresses in borrower database of the Armidale City Public Library to map the spatial distribution of its borrowers. Using this technique it is possible to identify areas of high and low use.

Abstract

Reviews the current market for CD-ROM databases with particular reference to the online versus CD-ROM versus print debate. Concludes that the most likely scenario is a steady convergence of technologies, at least until the end of the century. Review the current and the most likely future developments in the area of CD-ROM database contents, software, hardware, and marketing. Concludes that users will choose databases on the basis of such factors as: ease of use; power of use; storage and delivery capacity; quality; functionaliy; timeliness; overall appeal; and real cost, not just price. Lists the most likely candidates for successful CD-ROM database development; not yet available. Concludes that Windows user faces will steadily replace DOS based systems, but not unless the Windows replacements are truly better and not just different. Recommends that both Windows and DOS interfaces be loaded onto the same CD-ROM with each database allowing the user to choose which to use. Reviews likely developments in CD-ROM hardware and marketing strategies
