    Abstract
    The key political and strategic issues which needs to be addressed for the future development of the Australian subject gateways are: continued quality of content creation, integration of access to print and electronic resources, archiving and persistent identification, sustainability of services and service integration. These issues will be more effectively tackled internationally, and the Australian subject gateways are keen to work with international collaborators to achieve a mutually beneficial outcome

    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

    Abstract
    NOVAGate is a subject-based information gateway covering electronic resources in the agricultural, veterinary and related fields. The service, which opened in July 1998, is produced by the veterinary and agricultural libraries of the 5 Nordic countries - Denmark, Finland, Iceland, Norway and Sweden - which serve the NOVA University. The gateway covers Nordic and European resources as well as the resources of international organizations, but being planned is a network of subject gateways which will give access to a wide range of international quality resources within the agricultural, veterinary and related fields. The service uses the ROADS software

    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
    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
    Project SSG-FI at SUB Göttingen provides special subject gateways to international high quality Internet resources for scientific users. Internet sites are selected by subject specialists and described using an extension of qualified Dublin Core metadata. A basic evaluation is added. These descriptions are freely available and can be searched and browsed. These are now subject gateways for 3 subject ares: earth sciences (GeoGuide); mathematics (MathGuide); and Anglo-American culture (split into HistoryGuide and AnglistikGuide). Together they receive about 3.300 'hard' requests per day, thus reaching over 1 million requests per year. The project SSG-FI behind these guides is open to collaboration. Institutions and private persons wishing to contribute can notify the SSG-FI team or send full data sets. Regular contributors can request registration with the project to access the database via the Internet and create and edit records

    Abstract
    Wikipedia (the free online encyclopedia that anyone can edit) is having a huge impact on how a great many people gather information about the world. So, it is important for epistemologists and information scientists to ask whether people are likely to acquire knowledge as a result of having access to this information source. In other words, is Wikipedia having good epistemic consequences? After surveying the various concerns that have been raised about the reliability of Wikipedia, this article argues that the epistemic consequences of people using Wikipedia as a source of information are likely to be quite good. According to several empirical studies, the reliability of Wikipedia compares favorably to the reliability of traditional encyclopedias. Furthermore, the reliability of Wikipedia compares even more favorably to the reliability of those information sources that people would be likely to use if Wikipedia did not exist (viz., Web sites that are as freely and easily accessible as Wikipedia). In addition, Wikipedia has a number of other epistemic virtues (e.g., power, speed, and fecundity) that arguably outweigh any deficiency in terms of reliability. Even so, epistemologists and information scientists should certainly be trying to identify changes (or alternatives) to Wikipedia that will bring about even better epistemic consequences. This article suggests that to improve Wikipedia, we need to clarify what our epistemic values are and to better understand why Wikipedia works as well as it does. Somebody who reads Wikipedia is rather in the position of a visitor to a public restroom, says Mr. McHenry, Britannica's former editor. It may be obviously dirty, so that he knows to exercise great care, or it may seem fairly clean, so that he may be lulled into a false sense of security. What he certainly does not know is who has used the facilities before him. One wonders whether people like Mr. McHenry would prefer there to be no public lavatories at all.

    Rez. in: B.I.T. online 6(2003) H.3, S.298-299 (J. Plieninger): "Wer im vorigen Heft von B.I.T.online den Fachbeitrag von Hermann Rösch über Bibliothekarische Auskunft im Web gelesen und sich daraufhin überlegt, einen solchen Dienst einzuführen, für den wäre dieses Buch das geeignete Mittel, sich für die Einführung einer Online-Auskunft fit zu machen. Die Autorin ist in der amerikanischen Internet Librarian- und Reference Librarian-Szene wohlbekannt: 1993 verfasste sie mit zwei Mitautoren Crossing the Internet Treshold, ein Tutorial für die Nutzung des Netzes, welches für die Profession eine Hilfestellung für die breite Nutzung des Internets bot. Das hier besprochene Buch könnte eine ähnliche Funktion für die Einführung der Virtual Reference bekommen: Es bietet einen Selbstlernkurs, welcher anschaulich die Grundlagen und die Grundhaltung bei der Implementation eines solchen Dienstes vermittelt. Was ist alles in diesem Kurs enthalten? Der erste Teil des Buches behandelt den Entscheidungsprozess, einen Online-Auskunftsdienst einzuführen: Es werden Vor- und Nachteile diskutiert, die Bedürfnisse der Benutzer untersucht ("There will always be a need for a human consultant to satisfy the needs of the information seeker.") und die Grundlagen der Entscheidungsfindung für eine geeignete Software behandelt. Der zweite Teil handelt dann von den Fragen der "Einrichtung" des virtuellen Auskunftsplatzes. Hier gibt es z.B. eine Schulung in den besonderen Kommunikationsformen, welche beim Chat zu beachten sind, eine Einbettung des neuen Dienstes in das Leitbild, die Geschäftsordnung bzw. Arbeitsorganisation der Bibliothek ("library policies") und zuletzt die komfortable Ausstattung des Auskunftsplatzes für Benutzer und Beschäftigte bis hin zu Fragen der Evaluation und Qualitätssicherung. Der dritte Teil behandelt die Aufgabe, einen Dienst zu implementieren, der sich selbst trägt, indem man ein Marketing für den neuen Dienst einrichtet, das ihn auf herkömmlichen und neuen Wegen promotet und ihn benutzerfreundlich ausgestaltet.
    Rez. in BuB 56(2004) H.3: "Auskunfts- und Informationsdienst wird in den USA als unverzichtbare und wohl wichtigste bibliothekarische Tätigkeit betrachtet. Daher verwundert nicht, dass die Popularisierung des Internet Bibliothekare und Bibliotheken frühzeitig dazu veranlasst hat, ihre Auskunftsdienstleistungen im Web anzubieten. Dies geschah zunächst durch organisierte Auskunft per E-Mail, später per Webformular und vor allem seit 2000/2001 verstärkt per Chat. Als zusammenfassende Bezeichnung für diese Varianten wird meist der Begriff digital reference verwendet. In den USA, aber auch in Australien, Großbritannien oder Skandinavien schenkt man dem Thema Digital Reference schon seit mehreren Jahren größte Aufmerksamkeit. Die Zahl der bislang dazu publizierten Fachaufsätze lag Ende 2003 bereits weit über 600, jährlich im November findet seit 1999 die »Digital Reference Conference« statt, und mit DIG_REF sowie LiveReference existieren zwei Diskussionslisten, die sich ausschließlich mit Fragen bibliothekarischer Auskunft im Internet beschäftigen. Im vergangenen Jahr sind in den USA allein vier umfangreiche Monographien zu Digital Reference erschienen, darunter das hier zu besprechende Werk von Anne Lipow. ... Gegenwärtig deutet sich an, dass das Thema Digital Reference, Online-Auskunft oder Auskunft per Chat in deutschen Bibliotheken auf mehr Interesse stößt als in den vergangenen Jahren. Nachdem bislang vorwiegend (einige wenige) wissenschaftliche Bibliotheken ChatAuskunft anbieten, haben mehrere Öffentliche Bibliotheken, darunter die ZLB Berlin und die Stadtbücherei Frankfurt am Main, angekündigt, zukünftig auchAuskunftperChatanbieten zu wollen. Eine wichtige Rolle spielt in diesem Zusammenhang der weltweite Auskunftsverbund QuestionPoint, der von OCLC gemeinsam mit der Library of Congress betrieben wird. Sowohl denjenigen, die sich noch im Unklaren sind, als auch jenen, die entsprechende Planungen bereits beschlossen haben, kann der Band von Anne Lipow nur wärmstens empfohlen werden." (H. Rösch)

    Abstract
    The authors report on the findings of a usability test conducted to evaluate the usability of the VeriaGrid online system. The VeriaGrid (www.theveriagrid.org) is a prototype virtual map that focuses on the provision of information related to the cultural heritage of the city of Veria (Greece). It has been developed under the Light Project by the Central Public Library of Veria (www.libver.gr). It is an interactive application that includes various functional or thematic areas such as an interactive digital map of Veria, image gallery, videoclips, panoramic site photos, and general information about the city of Veria. The findings of the usability test revealed that users had some difficulties in using novel features of the digital map (such as the Recommended Points and the Routes functions) and finding textual information about cultural heritage of the city of Veria. Users, however, were satisfied with the overall usability of the system. In light of these findings, some recommendations for improving the usability of the system are made.

    Abstract
    The purpose of this paper is to identify, describe, evaluate and compare South African search engines, directories and portals. The comparative evaluation entailed analysis of six search engines by means of a checklist of desirable features, as well as a performance test by means of sample searches. The following aspects and features are covered in the checklist: database characteristics, search facilities and techniques, search results and portal services. In the performance test the local search engines were also compared with three international ones. Aardvark was rated the best local search engine judging by its performance in the sample searches, but it was outperformed by two of the international engines, Alta Vista and FAST, with regard to the total number of relevant hits retrieved. The results of the investigation will be of use to searchers in their selection of appropriate search tools and to search engine developers in the process of improving their systems

    Abstract
    By Internet resources Zhang means any electronic file accessible by any Internet protocol. Their usage is determined by an examination of the citations to such sources in a nine-year sample of four print and four electronic LIS journals, by a survey of editors of these journals, and by a survey of scholars with "in press" papers in these journals. Citations were gathered from Social Science Citation Index and manually classed as e-sources by the format used. All authors with "in press" papers were asked about their use and opinion of Internet sources and for any suggestions for improvement. Use of electronic sources is heavy and access is very high. Access and ability explain most usage while satisfaction was not significant. Citation of e-journals increases over the eight years. Authors report under citation of e-journals in favor of print equivalents. Traditional reasons are given for citing and not citing, but additional reasons are also present for e-journals.

    Rez. in: c't 2002, H.23, S.229 (T.J. Schult): "Mac-Anwender hatten bisher keine große Auswahl bei Multimedia-Enzyklopädien: entweder ein grottenschlechtes Kosmos Kompaktwissen, das dieses Jahr letztmalig erscheinen soll und sich dabei als Systhema Universallexikon tarnt. Oder ein Brockhaus in Text und Bild mit exzellenten Texten, aber flauer Medienausstattung. Die von Acclaim in Deutschland vertriebenen Britannica-Enzyklopädien stellen eine ausgezeichnete Alternative für den des Englischen Kundigen dar. Während früher nur Einfach-Britannicas auf dem Mac liefen, gilt dies nun für alle drei Versionen Student, Deluxe und Ultimate Reference Suite. Die Suite enthält dabei nicht nur alle 75 000 Artikel der 32 Britannica-Bände, sondern auch die 15 000 der Student Encyclopaedia, eines eigenen Schülerlexikons, das durch sein einfaches Englisch gerade für Nicht-Muttersprachler als Einstieg taugt. Wer es noch elementarer haben möchte, klickt sich zur Britannica Elementary Encyclopaedia, welche unter der gleichen Oberfläche wie die anderen Werke zugänglich ist. Schließlich umfasst die Suite einen Weltatlas sowie einsprachige Wörterbücher und Thesauri von Merriam-Webster in der Collegiate- und Student-Ausbaustufe mit allein 555 000 Definitionen, Synonymen und Antonymen. Wer viel in englischer Sprache recherchiert oder gar schreibt, leckt sich angesichts dieses Angebots (EUR 99,95) die Finger, zumal die Printausgabe gut 1600 Euro kostet. Die Texte sind einfach kolossal - allein das Inhaltsverzeichnis des Artikels Germany füllt sieben Bildschirmseiten. Schon die Inhalte aus den BritannicaBänden bieten mehr als doppelt so viel Text wie die rund tausend Euro kostende Brockhaus Enzyklopädie digital (c't 22/02, S. 38). Allein die 220 000 thematisch einsortierten Web-Links sind das Geld wert. Wer die 2,4 Gigabyte belegende Komplettinstallation wählt, muss sogar nie mehr die DVD (alternativ vier CD-ROMs) einlegen. Dieses Jahr muss sich niemand mehr mit dem Britannica-typischen Kuddelmuddel aus Lexikonartikeln und vielen, vielen Jahrbüchern herumschlagen - außer dem Basistext der drei Enzyklopädien sind 'nur' die zwei Jahrbücher 2001 und 2002 getrennt aufgeführt. Wer des Englischen mächtig ist, mag hier die gute Gelegenheit zum Kauf nutzen."

    Abstract
    Wikipedia is fast becoming a key information source for many despite criticism that it is unreliable and inaccurate. A number of recommendations have been made to sort the chaff from the wheat in Wikipedia, among which is the idea of color-coding article segment edits according to age (Cross, 2006). Using data collected as part of a wider study published in Nature, this article examines the distribution of errors throughout the life of a select group of Wikipedia articles. The survival time of each error edit in terms of the edit counts and days was calculated and the hypothesis that surviving material added by older edits is more trustworthy was tested. Surprisingly, we find that roughly 20% of errors can be attributed to surviving text added by the first edit, which confirmed the existence of a first-mover effect (Viegas, Wattenberg, & Kushal, 2004) whereby material added by early edits are less likely to be removed. We suggest that the sizable number of errors added by early edits is simply a result of more material being added near the beginning of the life of the article. Overall, the results do not provide support for the idea of trusting surviving segments attributed to older edits because such edits tend to add more material and hence contain more errors which do not seem to be offset by greater opportunities for error correction by later edits.

    Abstract
    Academic and special libraries are in the midst of a shift toward hybrid collections. This shift from collection ownership to an information access model supports the distributed nature of learning and work. However, unanticipated consequences of these changes are emerging. One confounding result is a visible pattern of discontinuities in collections, with unique features for electronic products. Patterns of discontinuities encountered included the occurrence of intermittent holes and unintentionally masked information. This has both immediate and long-term implications for library users and services, and there are not yet coherent measures to assess these sorts of outcomes. A framework is required for the systematic evaluation of the effects of new systems such as bundled electronic resources. This research suggests that evaluating both use and non-use of electronic collections will supplement other acquisitions and service measures to support long-range planning and decision-making.
