    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
    Under the auspices of the Desire II project, researchers at NetLab and OCLC are providing searching and browsing of a test collection of engineering documents on the Web. The goal of the project is to explore simple methods of automatic classification to provide subject browsing of a robot-generated engineering index. At NetLab the documents are automatically classified and organized using an engineering-specific scheme, the Engineering Index (Ei) Thesaurus and Classification; at OCLC the Dewey Decimal Classification (DDC), a general knowledge organization scheme, is being used

    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.

    Abstract
    If you are an indexer who is accustomed to working in solitude with static words, you might face some big surprises in the production of a multimedia CD-ROM. You will not be working alone. You will not be working from a manuscript. Your dexterity with a dedicated software tool for indexing will be irrelevant. The coding or tagging might not be your worry either, because it will likely be done by members of a separate technical staff. The CD-ROM can currently hold 660 megabytes of data. Its production is a massive team effort. Because of the sheer volume of data involved, it is unlikely that one indexer working alone can handle the job in a reasonable period of time. The database for the actual index entries is likely to have been designed specifically for the project at hand, so the indexers will learn the software tools on the job. The entire project will probably be onscreen. So, if you choose to thrust yourself into this teeming amalgam of production, what are the prerequisites and what new things can you expect to learn? CD-ROM is an amorphous new medium with few rules. Your most important resume items might be your flexibility, imagination, and love of words. What remains unchanged from traditional back-of-the-book indexing is the need for empathy with the user; you will still need to come up with exactly the right word for the situation. What is new here is the situation: you might learn to envision the words that correspond to non-textual media such as graphics, photos, video clips, and musical passages. And because you will be dealing with vast amounts of textual and sensory data, you might find yourself rethinking the nature and purpose of an index as a whole. CD-ROM production can take many forms; three will be discussed here

    Abstract
    'I wish that I had been able to obtain such a guide when I started dealing with enquiries' - "Managing Information". 'By the time I got to it 3 staff had noticed it on the desk and written a note saying really good and can we have a copy' - "BBOB News". 'This is certainly a comforting and very useful guide for the information worker, particularly inexperienced or unqualified, staffing a general enquiry desk' - "New Library World". There is a queue, the phone is ringing, the photocopier has jammed and your enquirer is waiting for a response. You are stressed and you can feel the panic rising. Where do you go to find the information you need to answer the question promptly and accurately?Answering queries from users is one of the most important services undertaken by library and information staff. Yet it is also one of the most difficult, least understood subjects. There are still very few materials available to help frontline staff - often paraprofessional - develop their reader enquiry skills. This award-winning sourcebook is an essential guide to where to look to find the answers quickly. It is designed as a first point of reference for library and information practitioners, to be depended upon if they are unfamiliar with the subject of an enquiry - or wish to find out more. It is arranged in an easily searchable, fully cross-referenced A-Z list of around 150 of the subject areas most frequently handled at enquiry desks.Each subject entry lists the most important information sources and where to locate them, including printed and electronic sources, relevant websites and useful contacts for referral purposes. The authors use their extensive experience in reference work to offer useful tips, warn of potential pitfalls, and spotlight typical queries and how to tackle them. This new edition has been brought right up-to-date with all sources checked for currency and many new ones added. The searchability is enhanced by a comprehensive index to make those essential sources even easier to find - saving you valuable minutes! Offering quick and easy pointers to a multitude of information sources, this is an invaluable reference deskbook for all library and information staff in need of a speedy answer, in reference libraries, subject departments and other information units.

    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 (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: Spektrum der Wissenschaft 2003, H.7, S.95-96 (E. Reinecke): "Mehr als zweihundert Jahre lang stellte der Star unter den Nachschlagewerken, die Encyclopaedia Britannica, sich selbst als echt britischen Luxusartikel dar, obgleich sie schon seit den 1930er Jahren in Chicago produziert wird. Nicht nur die edle Ausstattung der Bände selbst beeindruckte den Kunden; auch der persönliche Besuch eines Lexikonvertreters vermittelte das Gefühl, hier einen besonderen Kauf zu tätigen. Der stolze Preis passte in diesen Rahmen: Schon die bescheidenste Ausgabe des Prachtwerks kostete über 3000 DM. Dann kam das Internet, und alles wurde anders. In Gestalt der Microsoft Encarta trat 1992 ein großmächtiger Konkurrent mit niedrigen Preisen auf. Sie konnte zwar die Qualität der ehrwürdigen »Britannica« nicht erreichen; doch wie in anderen Fällen siegte Masse über Klasse. 1996 hatten sich die Verkaufszahlen der »Britannica« halbiert, auch die Produktion einer eigenen CD-Rom-Version konnte die Talfahrt nicht mehr aufhalten. Sie endete noch im selben Jahr mit dem Verkauf des Traditionsunternehmens an einen Schweizer Investor. Für Computer- und Internetfans folgte eine Ära der Freude: Die neuen Eigentümer passten sich dem Trend der Zeit an und gaben den Verkauf über Vertreter zu Gunsten der digitalen Version auf. Wer zu diesem Zeitpunkt die Britannica erwerben wollte, mußte sich mit einer Scheibe zufrieden geben oder den Weg ins World Wide Web gehen. Im Internet waren die Artikel zunächst sogar umsonst zu haben. Heute werden drei verschiedene CDRom-/DVD-Versionen angeboten, und die Website der Encyclopxdia Britannica ist allseits bekannt und beliebt - allerdings nicht mehr kostenlos zugänglich. Wer mehr als Appetithäppchen will, muss sich auf ein Abonnement einlassen. Dieses ist schnell und einfach abgeschlossen; die Kundenfreundlichkeit der Site und ihrer Betreiber ist durchaus bemerkenswert. Nachdem die Entwicklung der elektronischen Britannica schon so weit vorangetrieben war, gab der Verlag 2002 wieder eine neue Devise aus: »Back to the roots«. Nach vier Jahren rein digitaler Vermarktung kommt eine überarbeitete Neuauflage in gedruckter Form auf den Markt. Nun kann der geneigte Leser sich wieder am Anblick von fast anderthalb Metern Buch erfreuen und trotzdem auf dem letzten Stand sein - zumindest kurzfristig. In der Darstellung des deutschen Vertreibers sind gar die CD-Rom-Versioneu nur noch eine »Ergänzung« zum »repräsentativen gedruckten Erzeugnis«. Was kann einen deutschen Leser bewegen, sich der Sprachhürde zum Trotz für die Encyclopxdia Britannica zu entscheiden - egal ob digital oder gedruckt? Der Umfang ist in der Tat beeindruckend. Allein der zwölfbändige erste Teil, die »Micropxdia«, enthält bereits die Stichwortartikel eines kompletten Lexikons. Das richtig tief gehende Wissen (»Knowledge in Depth«) steht in der 17 Bände umfassenden »Macropxdia«. Auf durchschnittlich zwanzig, gelegentlich bis zu 300 Seiten findet der Leser eine Art Überblicksvorlesung zu Themen wie »Telekommunikation«, »Algebra« oder »Die Schweiz«. So wird der Nachschlagende im besten Sinne zum Studierenden. Insgesamt kommen über 65 000 Artikel mit mehr als 24 000 Fotos, Karten und Illustrationen zusammen. Zur Erschließung dieser Fülle gibt es einen zweibändigen Index der Luxusklasse: mit 700 000 Einträgen, die zum Stich wort nicht nur Band und Seitenzahl, sondern auch die Spalte und die - obere oder untere - Spaltenhälfte nennen.
