    Rez. in: Mitt. VÖB 59(2006) H.3, S.95-98 (O. Oberhauser): "Dieser Sammelband der Herausgeber A. Spink & C. Cole ist kurz vor ihrem im letzten Heft der Mitteilungen der VÖB besprochenen zweiten Buch erschienen. Er wendet sich an Informationswissenschaftler, Bibliothekare, Sozialwissenschaftler sowie Informatiker mit Interesse am Themenbereich Mensch-Computer-Interaktion und präsentiert einen Einblick in die aktuelle Forschung zum kognitiv orientierten Information Retrieval. Diese Richtung, die von der Analyse der Informationsprobleme der Benutzer und deren kognitivem Verhalten bei der Benutzung von Informationssystemen ausgeht, steht in einem gewissen Kontrast zum traditionell vorherrschenden IR-Paradigma, das sich auf die Optimierung der IR-Systeme und ihrer Effizienz konzentriert. "Cognitive information retrieval" oder CIR (natürlich geht es auch hier nicht ohne ein weiteres Akronym ab) ist ein interdisziplinärer Forschungsbereich, der Aktivitäten aus Informationswissenschaft, Informatik, Humanwissenschaften, Kognitionswissenschaft, Mensch-Computer-Interaktion und anderen informationsbezogenen Gebieten inkludiert.
    CIR Processes - A multitasking framework for cognitive information retrieval, von Amanda Spink und Charles Cole (Australien/Kanada), sieht - im Gegensatz zu traditionellen Ansätzen - die simultane Bearbeitung verschiedener Aufgaben (Themen) während einer Informationssuche als den Normalfall an und analysiert das damit verbundene Benutzerverhalten. - Explanation in information seeking and retrieval, von Pertti Vakkari und Kalervo Järvelin (Tampere), plädiert anhand zweier empirischer Untersuchungen für die Verwendung des aufgabenorientierten Ansatzes ("task") in der IR-Forschung, gerade auch als Bindeglied zwischen nicht ausreichend mit einander kommunizierenden Disziplinen (Informationswissenschaft, Informatik, diverse Sozialwissenschaften). - Towards an alternative information retrieval system for children, von Jamshid Beheshti et al. (Montréal), berichtet über den Stand der IR-Forschung für Kinder und schlägt vor, eine Metapher aus dem Sozialkonstruktivismus (Lernen als soziales Verhandeln) als Gestaltungsprinzip für einschlägige IR-Systeme zu verwenden. CIR Techniques - Implicit feedback: using behavior to infer relevance, von Diane Kelly (North Carolina), setzt sich kritisch mit den Techniken zur Analyse des von Benutzern von IR-Systemen geäußerten Relevance-Feedbacks - explizit und implizit - auseinander. - Educational knowledge domain visualizations, von Peter Hook und Katy Börner (Indiana), beschreibt verschiedene Visualisierungstechniken zur Repräsentation von Wissensgebieten, die "Novizen" bei der Verwendung fachspezifischer IR-Systeme unterstützen sollen. - Learning and training to search, von Wendy Lucas und Heikki Topi (Massachusetts), analysiert, im breiteren Kontext der Information- Seeking-Forschung, Techniken zur Schulung von Benutzern von IRSystemen.

    Abstract
    Suchmaschinen sind die neuen »Gatekeeper« im Internet. Sie kanalisieren unsere Aufmerksamkeit und haben entscheidenden Einfluss darauf, welche Inhalte wie zugänglich sind. Ohne sie sind Informationen im Netz nur schwer auffindbar. Allerdings: Nur wenige Nutzer wissen, wie man Suchmaschinen optimal bedient und wie sie funktionieren. Sie sind anfällig für Manipulationen (»Spamming«) und verschaffen auch ungewollt Zugang zu illegalen und jugendgefährdenden Inhalten. Wie können Suchmaschinen trotzdem ihrer Verantwortung als zentrale Informationssortierer gerecht werden? Eine groß angelegte Untersuchung der Bertelsmann Stiftung stellt diese Beobachtungen auf eine wissenschaftliche Basis. Eine Nutzerbefragung, ein Laborexperiment und ein Leistungsvergleich geben Aufschluss über Image, Bedienerfreundlichkeit und Qualität von Suchmaschinen. Aus dieser Analyse entwickeln die Autoren einen Code of Conduct für Suchmaschinenbetreiber, der einen möglichst objektiven und transparenten Zugang zu Informationen im Netz garantieren soll. Das Buch ist dreigeteilt: Im ersten umfangreichen Teil (bis Seite 490) werden, nach einer Einführung in die Suchmaschinenproblematik und ihr Umfeld, Qualität und Nutzung erforscht: Nach der Marktanalyse der deutschsprachigen Suchdienste werden ausgewählte einem Leistungsvergleich unterzogen. Der Gefährdung von Kindern und Jugendlichen widmet sich das Kapitel Problemanalyse. Wie erfolgreich Spamversuche die Suchergebnisse beeinflussen können, wird anschließend dargestellt. Den Kenntnissen und Einstellungen von Nutzern von Suchdiensten widmet sich ein ausführliches Kapitel. Nutzungshäufigkeit, Suchprozesse und Vorgehensweisen sind detailliert untersucht worden. Die Ergebnisse der Laborexperimente liefern konkrete Einsichten, auf über 100 Seiten verständlich beschrieben. In Kapitel 6 werden die angewandten Methoden ausführlich erläutert. Das angefügte Glossar könnte ausführlicher sein. Der zweite Teil appelliert an die gesellschaftliche Verantwortung der deutschen Suchdienstbetreiber, indem ein Code of Conduct für Suchmaschinen entworfen wird. Im dritten Teil wird auf die Entwicklungen in der Suchmaschinenlandschaft eingegangen, die sich durch Firmenübernahmen und die Monopolstellung von Google ergeben haben.

    Rez. in: Mitt. VÖB 59(2006) H.3, S.100-103 (O. Oberhauser): "Dieses als Band 3507 der bekannten, seit 1973 erscheinenden Springer-Serie Lecture Notes in Computer Science (LNCS) publizierte Buch versammelt die Vorträge der 5. Tagung "Conceptions of Library and Information Science". CoLIS hat sich in den letzten anderthalb Jahrzehnten als internationales Forum für die Präsentation und Rezeption von Forschung auf den Fachgebieten Informatik und Informationswissenschaft etabliert. Auf die 1992 in Tampere (Finnland) anlässlich des damals 20jährigen Bestehens des dortigen Instituts für Informationswissenschaft abgehaltene erste Tagung folgten weitere in Kopenhagen (1996), Dubrovnik (1999) und Seattle, WA (2002). Die zuletzt an der Strathclyde University in Glasgow (2005) veranstaltete Konferenz war dem Thema "Context" im Rahmen der informationsbezogenen Forschung gewidmet, einem komplexen, dynamischen und multidimensionalen Begriff von grosser Bedeutung für das Verhalten und die Interaktion von Mensch und Maschine. . . .
    Mehrere Beiträge befassen sich mit dem Problem der Relevanz. Erica Cosijn und Theo Bothma (Pretoria) argumentieren, dass für das Benutzerverhalten neben der thematischen Relevanz auch verschiedene andere Relevanzdimensionen eine Rolle spielen und schlagen auf der Basis eines (abermals auf Ingwersen zurückgehenden) erweiterten Relevanzmodells vor, dass IR-Systeme die Möglichkeit zur Abgabe auch kognitiver, situativer und sozio-kognitiver Relevanzurteile bieten sollten. Elaine Toms et al. (Kanada) berichten von einer Studie, in der versucht wurde, die schon vor 30 Jahren von Tefko Saracevic3 erstellten fünf Relevanzdimensionen (kognitiv, motivational, situativ, thematisch und algorithmisch) zu operationalisieren und anhand von Recherchen mit einer Web-Suchmaschine zu untersuchen. Die Ergebnisse zeigten, dass sich diese fünf Dimensionen in drei Typen vereinen lassen, die Benutzer, System und Aufgabe repräsentieren. Von einer völlig anderen Seite nähern sich Olof Sundin und Jenny Johannison (Boras, Schweden) der Relevanzthematik, indem sie einen kommunikationsorientierten, neo-pragmatistischen Ansatz (nach Richard Rorty) wählen, um Informationssuche und Relevanz zu analysieren, und dabei auch auf das Werk von Michel Foucault zurückgreifen. Weitere interessante Artikel befassen sich mit Bradford's Law of Scattering (Hjørland & Nicolaisen), Information Sharing and Timing (Widén-Wulff & Davenport), Annotations as Context for Searching Documents (Agosti & Ferro), sowie dem Nutzen von neuen Informationsquellen wie Web Links, Newsgroups und Blogs für die sozial- und informationswissenschaftliche Forschung (Thelwall & Wouters). In Summe liegt hier ein interessantes und anspruchsvolles Buch vor - inhaltlich natürlich nicht gerade einheitlich und geschlossen, doch dies darf man bei einem Konferenzband ohnedies nicht erwarten. Manche der abgedruckten Beiträge sind sicher nicht einfach zu lesen, lohnen aber die Mühe. Auch für Praktiker aus Bibliothek und Information ist einiges dabei, sofern sie sich für die wissenschaftliche Basis ihrer Tätigkeit interessieren. Fachlich einschlägige Spezial- und grössere Allgemeinbibliotheken sollten das Werk daher unbedingt führen.

    Abstract
    In this collection of nearly 50 articles written by librarians, computer specialists, and other information professionals, the reader finds 10 chapters, each devoted to a problem or a side effect that has emerged since the introduction of the Internet: control over selection, survival of the book, training users, adapting to users' expectations, access issues, cost of technology, continuous retraining, legal issues, disappearing data, and how to avoid becoming blind sided. After stating a problem, each chapter offers solutions that are subsequently supported by articles. The editor's comments, which appear throughout the text, are an added bonus, as are the sections concluding the book, among them a listing of useful URLs, a works-cited section, and a comprehensive index. This book has much to recommend it, especially the articles, which are not only informative, thought-provoking, and interesting but highly readable and accessible as well. An indispensable tool for all librarians.

    Rez. in: JASIST 55(2004) no.11, S.1025-1026 (D.E. Agosto): ""Did you ever feel as though the Internet has caused you to lose control of your library?" So begins the introduction to this volume of over 50 articles, essays, library policies, and other documents from a variety of sources, most of which are library journals aimed at practitioners. Volume editor Block has a long history of library service as well as an active career as an online journalist. From 1977 to 1999 she was the Associate Director of Public Services at the St. Ambrose University library in Davenport, Iowa. She was also a Fox News Online weekly columnist from 1998 to 2000. She currently writes for and publishes the weekly ezine Exlibris, which focuses an the use of computers, the Internet, and digital databases to improve library services. Despite the promising premise of this book, the final product is largely a disappointment because of the superficial coverage of its issues. A listing of the most frequently represented sources serves to express the general level and style of the entries: nine articles are reprinted from Computers in Libraries, five from Library Journal, four from Library Journal NetConnect, four from ExLibris, four from American Libraries, three from College & Research Libraries News, two from Online, and two from The Chronicle of Higher Education. Most of the authors included contributed only one item, although Roy Tennant (manager of the California Digital Library) authored three of the pieces, and Janet L. Balas (library information systems specialist at the Monroeville Public Library in Pennsylvania) and Karen G. Schneider (coordinator of lii.org, the Librarians' Index to the Internet) each wrote two. Volume editor Block herself wrote six of the entries, most of which have been reprinted from ExLibris. Reading the volume is muck like reading an issue of one of these journals-a pleasant experience that discusses issues in the field without presenting much research. Net Effects doesn't offer much in the way of theory or research, but then again it doesn't claim to. Instead, it claims to be an "idea book" (p. 5) with practical solutions to Internet-generated library problems. While the idea is a good one, little of the material is revolutionary or surprising (or even very creative), and most of the solutions offered will already be familiar to most of the book's intended audience.
    Unlike muck of the professional library literature, Net Effects is not an open-aimed embrace of technology. Block even suggests that it is helpful to have a Luddite or two an each library staff to identify the setbacks associated with technological advances in the library. Each of the book's 10 chapters deals with one Internet-related problem, such as "Chapter 4-The Shifted Librarian: Adapting to the Changing Expectations of Our Wired (and Wireless) Users," or "Chapter 8-Up to Our Ears in Lawyers: Legal Issues Posed by the Net." For each of these 10 problems, multiple solutions are offered. For example, for "Chapter 9-Disappearing Data," four solutions are offered. These include "Link-checking," "Have a technological disaster plan," "Advise legislators an the impact proposed laws will have," and "Standards for preservation of digital information." One article is given to explicate each of these four solutions. A short bibliography of recommended further reading is also included for each chapter. Block provides a short introduction to each chapter, and she comments an many of the entries. Some of these comments seem to be intended to provide a research basis for the proposed solutions, but they tend to be vague generalizations without citations, such as, "We know from research that students would rather ask each other for help than go to adults. We can use that (p. 91 )." The original publication dates of the entries range from 1997 to 2002, with the bulk falling into the 2000-2002 range. At up to 6 years old, some of the articles seem outdated, such as a 2000 news brief announcing the creation of the first "customizable" public library Web site (www.brarydog.net). These critiques are not intended to dismiss the volume entirely. Some of the entries are likely to find receptive audiences, such as a nuts-and-bolts instructive article for making Web sites accessible to people with disabilities. "Providing Equitable Access," by Cheryl H. Kirkpatrick and Catherine Buck Morgan, offers very specific instructions, such as how to renovate OPAL workstations to suit users with "a wide range of functional impairments." It also includes a useful list of 15 things to do to make a Web site readable to most people with disabilities, such as, "You can use empty (alt) tags (alt="') for images that serve a purely decorative function. Screen readers will skip empty (alt) tags" (p. 157). Information at this level of specificity can be helpful to those who are faced with creating a technological solution for which they lack sufficient technical knowledge or training.
    Some of the pieces are more captivating than others and less "how-to" in nature, providing contextual discussions as well as pragmatic advice. For example, Darlene Fichter's "Blogging Your Life Away" is an interesting discussion about creating and maintaining blogs. (For those unfamiliar with the term, blogs are frequently updated Web pages that ]ist thematically tied annotated links or lists, such as a blog of "Great Websites of the Week" or of "Fun Things to Do This Month in Patterson, New Jersey.") Fichter's article includes descriptions of sample blogs and a comparison of commercially available blog creation software. Another article of note is Kelly Broughton's detailed account of her library's experiences in initiating Web-based reference in an academic library. "Our Experiment in Online Real-Time Reference" details the decisions and issues that the Jerome Library staff at Bowling Green State University faced in setting up a chat reference service. It might be useful to those finding themselves in the same situation. This volume is at its best when it eschews pragmatic information and delves into the deeper, less ephemeral libraryrelated issues created by the rise of the Internet and of the Web. One of the most thought-provoking topics covered is the issue of "the serials pricing crisis," or the increase in subscription prices to journals that publish scholarly work. The pros and cons of moving toward a more free-access Web-based system for the dissemination of peer-reviewed material and of using university Web sites to house scholars' other works are discussed. However, deeper discussions such as these are few, leaving the volume subject to rapid aging, and leaving it with an audience limited to librarians looking for fast technological fixes."

Wie die Herausgeber Allen Foster und Pauline Rafferty - beide aus dem Department of Information Studies an der Aberystwyth University (Wales) - in ihrer Einleitung betonen, sind Theorie und Praxis der Wissensorganisation im Internet- Zeitalter nicht mehr nur die Domäne von Informationswissenschaftlern und Bibliotheksfachleuten, sondern auch von Informatikern, Semantic-Web-Entwicklern und Wissensmanagern aus den verschiedensten Institutionen; neben das wissenschaftliche Interesse am Objektbereich ist nun auch das kommerzielle getreten.
