- Neben Anwendungen und Beispielen aus verschiedenen Ländern belegt der Autor anhand beeindruckender Beispiele, wie wenig sinnstiftend Wort-/Wortsstammfilter sind (Seite 84 bis 91). Ein Hauptproblem in der Informations- und Wissensgesellschaft sieht er darin: »Die Bequemlichkeit der Nutzer« führe zu einer selbst auferlegten »Informationsbeschränkung« bei der Nutzung von Suchmaschinen (Seite 18 bis 21). Dementsprechend sieht Strzolka in der »fehlenden Informationskompetenz und Zensur« eine »unheilvolle Allianz« (Seite 24). »Sich auf Suchmaschinen als objektive Instanz zu verlassen«, heißt es später (Seite 56), »ist so naiv, wie die Bibel als einzige Informationsquelle für das Leben in der modernen Welt zu nutzen«. Denn: »Suchmaschinen zensieren nicht - Ihre Betreiber organisieren Zensur.« Internetzensur Auf 25 Seiten (Seite 74 bis 99) dokumentiert Strzolka mit bemerkenswerten Beispielen, wie das in der Praxis geschieht. Nach Strzolka beteiligen sich Bibliothekare auch an der (Internet-)Zensur (Seite 22 f, mit Beispielen auf Seite 34). Hier wäre eine tiefergehende Auseinsandersetzung angebracht gewesen. Beeindruckend dabei, wie Strzolka über »Zensur und Idiotenfallen« (Seite 84 bis 90) berichtet. »Das Internet ist eine ausgesprochen heterogene Datensammlung und >keineswegs die größte Bibliothek der Welt>, wie immer zu hören ist.« (Seite 25) Denn: »Informationsportale verengen den Weg in die Wissensgesellschaft [...], weil sie die Fokussierung auf gewünschte Quellen [fördern]« (Seite 25). Vor diesem Hintergrund müsse deshalb eher von »Informationsbeschränkung« als von »Informationsvielfalt« die Rede sein.

- Rez. in: KO 31(2004) no.2, S.117-118 (D. Campbell): "This excellent volume offers 22 papers delivered at an IFLA Satellite meeting in Dublin Ohio in 2001. The conference gathered together information and computer scientists to discuss an important and difficult question: in what specific ways can the accumulated skills, theories and traditions of librarianship be mobilized to face the challenges of providing subject access to information in present and future networked information environments? The papers which grapple with this question are organized in a surprisingly deft and coherent way. Many conferences and proceedings have unhappy sessions that contain a hodge-podge of papers that didn't quite fit any other categories. As befits a good classificationist, editor I.C. McIlwaine has kept this problem to a minimum. The papers are organized into eight sessions, which split into two broad categories. The first five sessions deal with subject domains, and the last three deal with subject access tools. The five sessions and thirteen papers that discuss access in different domains appear in order of in creasing intension. The first papers deal with access in multilingual environments, followed by papers an access across multiple vocabularies and across sectors, ending up with studies of domain-specific retrieval (primarily education). Some of the papers offer predictably strong work by scholars engaged in ongoing, long-term research. Gerard Riesthuis offers a clear analysis of the complexities of negotiating non-identical thesauri, particularly in cases where hierarchical structure varies across different languages. Hope Olson and Dennis Ward use Olson's familiar and welcome method of using provocative and unconventional theory to generate meliorative approaches to blas in general subject access schemes. Many papers, an the other hand, deal with specific ongoing projects: Renardus, The High Level Thesaurus Project, The Colorado Digitization Project and The Iter Bibliography for medieval and Renaissance material. Most of these papers display a similar structure: an explanation of the theory and purpose of the project, an account of problems encountered in the implementation, and a discussion of the results, both promising and disappointing, thus far. Of these papers, the account of the Multilanguage Access to Subjects Project in Europe (MACS) deserves special mention. In describing how the project is founded an the principle of the equality of languages, with each subject heading language maintained in its own database, and with no single language used as a pivot for the others, Elisabeth Freyre and Max Naudi offer a particularly vivid example of the way the ethics of librarianship translate into pragmatic contexts and concrete procedures. The three sessions and nine papers devoted to subject access tools split into two kinds: papers that discuss the use of theory and research to generate new tools for a networked environment, and those that discuss the transformation of traditional subject access tools in this environment. In the new tool development area, Mary Burke provides a promising example of the bidirectional approach that is so often necessary: in her case study of user-driven classification of photographs, she user personal construct theory to clarify the practice of classification, while at the same time using practice to test the theory. Carol Bean and Rebecca Green offer an intriguing combination of librarianship and computer science, importing frame representation technique from artificial intelligence to standardize syntagmatic relationships to enhance recall and precision.

- Chapter 2 (Technology and People) focuses an several theories of technological acceptance and diffusion. Unfortunately, Bruce's presentation is somewhat confusing as he moves from one theory to next, never quite connecting them into a logical sequence or coherent whole. Two theories are of particular interest to Bruce: the Theory of Diffusion of Innovations and the Theory of Planned Behavior. The Theory of Diffusion of Innovations is an "information-centric view of technology acceptance" in which technology adopters are placed in the information flows of society from which they learn about innovations and "drive innovation adoption decisions" (p. 20). The Theory of Planned Behavior maintains that the "performance of a behavior is a joint function of intentions and perceived behavioral control" (i.e., how muck control a person thinks they have) (pp. 22-23). Bruce combines these two theories to form the basis for the Technology Acceptance Model. This model posits that "an individual's acceptance of information technology is based an beliefs, attitudes, intentions, and behaviors" (p. 24). In all these theories and models echoes a recurring theme: "individual perceptions of the innovation or technology are critical" in terms of both its characteristics and its use (pp. 24-25). From these, in turn, Bruce derives a predictive theory of the role personal perceptions play in technology adoption: Personal Innovativeness of Information Technology Adoption (PIITA). Personal inventiveness is defined as "the willingness of an individual to try out any new information technology" (p. 26). In general, the PIITA theory predicts that information technology will be adopted by individuals that have a greater exposure to mass media, rely less an the evaluation of information technology by others, exhibit a greater ability to cope with uncertainty and take risks, and requires a less positive perception of an information technology prior to its adoption. Chapter 3 (A Focus an Usings) introduces the User-Centered Paradigm (UCP). The UCP is characteristic of the shift of emphasis from technology to users as the driving force behind technology and research agendas for Internet development [for a dissenting view, see Andrew Dillion's (2003) challenge to the utility of user-centerness for design guidance]. It entails the "broad acceptance of the user-oriented perspective across a range of disciplines and professional fields," such as business, education, cognitive engineering, and information science (p. 34).
