- Rez. in: KO 50(2003) no.1, S.45-46 (L.M. Given): "In her own preface to this work, the author notes her lifelong fascination with classification and order, as well as her more recent captivation with the Internet - a place of "chaos in need of organization" (xi). Sorting out the Web examines current efforts to organize the Web and is well-informed by the author's academic and professional expertise in information organization, information retrieval, and Web development. Although the book's level and tone are particularly relevant to a student audience (or others interested in Web-based subject access at an introductory level), it will also appeal to information professionals developing subject access systems across a range of information contexts. There are six chapters in the book, each describing and analyzing one core concept related to the organization of Web content. All topics are presented in a manner ideal for newcomers to the area, with clear definitions, examples, and visuals that illustrate the principles under discussion. The first chapter provides a brief introduction to developments in information technology, including an historical overview of information services, users' needs, and libraries' responses to the Internet. Chapter two introduces metadata, including core concepts and metadata formats. Throughout this chapter the author presents a number of figures that aptly illustrate the application of metadata in HTML, SGML, and MARC record environments, and the use of metadata tools (e.g., XML, RDF). Chapter three begins with an overview of classification theory and specific schemes, but the author devotes most of the discussion to the application of classification systems in the Web environment (e.g., Dewey, LCC, UDC). Web screen captures illustrate the use of these schemes for information sources posted to sites around the world. The chapter closes with a discussion of the future of classification; this is a particularly useful section as the author presents a listing of core journal and conference venues where new approaches to Web classification are explored. In chapter four, the author extends the discussion of classification to the use of controlled vocabularies. As in the first few chapters, the author first presents core background material, including reasons to use controlled vocabularies and the differences between preand post-coordinate indexing, and then discusses the application of specific vocabularies in the Web environment (e.g., Infomine's use of LCSH). The final section of the chapter explores failure in subject searching and the limitations of controlled vocabularies for the Web. Chapter five discusses one of the most common and fast-growing topics related to subject access an the Web: search engines. The author presents a clear definition of the term that encompasses classified search lists (e.g., Yahoo) and query-based engines (e.g., Alta Vista). In addition to historical background an the development of search engines, Schwartz also examines search service types, features, results, and system performance.

- Rez. in: B.I.T. online 6(2003) H.3, S.298 (J. Plieninger): "Elektronische Auskunftsdienste befinden sich gerade in der Entwicklung, und so ist es verdienstvoll von der FH Köln, in ihrer Institutsreihe einen Text über private Online-Auskunftsdienste zu veröffentlichen, welcher uns daran erinnert, dass die Konkurrenz nicht schläft, ja vielmehr schon länger am Markt tätig ist! Die Autorin deutet am Schluss zu Recht darauf hin, dass man analysieren müsse, warum die Kunden dieser Dienste nicht einen von Bibliotheken angebotenen Informationsdienst konsultieren. Vielleicht, weil Bibliotheken noch keine virtuelle Auskunft anbieten? Dann wird es Zeit, dies in Angriff zu nehmen! Am Anfang des Textes stehen Begriffsklärungen. Die Autorin schlägt vor, "Digital Reference" für Auskunftsdienste von Bibliotheken im Netz zu verwenden und "AskA"-Services (kommt von "Ask an expert") für die private Sphäre, seien es kommerzielle oder nichtkommerzielle Dienste. Bei diesen meist unentgeltlich zu nutzenden Diensten beantworten Experten frei gestellte Fragen. Die Autorin trennt solche Dienste von anderen, welche reine Foren darstellen (wie z.B. Newsgroups oder Chats), nur zu Zwecken von Firmen dienen, Meinungen transportieren oder Schlichtweg kostenpflichtig sind. Danach wird die Entwicklung solcher Dienste in den USA und hierzulande dargestellt. Solche Dienste gibt es seit 1995 und sie haben sich seitdem, wie das Netz selbst, fortwährend gewandelt, wie z.B. der angelsächsische Dienst AskJeeves oder das deutsche Auskunftsportal MeoMe, das mittlerweile in Freenet eingegliedert wurde. Danach wird eine Typologie der Dienste erstellt, einerseits nach der Intention der Betreiber und andererseits nach der Kommunikationsart. Hier sind zwei Aspekte bedeutsam: - manche Dienste sind unentgeltlich zu nutzen, aber nicht kostenlos, insofern man Werbung oder Public Relations zu ertragen hat und - die Crux bei solchen Diensten ist auch die Frage nach den "Experten", die antworten. Manche Dienste schulen ihre Mitarbeiter, aber dennoch ist die Frage zu stellen, in wie weit die Experten wirklich als solche anzusehen sind. Letzteres wird noch deutlicher bei der Lektüre der nun folgenden, mit Screenshots versehenen Besprechung einzelner Dienste (Askjeeves.com, Webhelp.com, MAD Scientist Network, Werweiss-was.de und Google Answers). Mehrere dieser Dienste arbeiten mit Archiven schon bisher gestellter Fragen und Antworten, was für bibliothekarische Digitale Auskunft eventuell auch eine attraktive Sache sein könnte. Bei der Lektüre der strukturiert angebotenen Besprechung wird klar, dass auch die private Konkurrenz noch nicht das Patentrezept gefunden hat: Askjeeves vertraut auf techisch ausgefuchste Lösungen und automatische Einbeziehung von Suchmaschinenergebnissen, bei Webhelp.com sind die Experten einerseits mit Fragezeichen zu betrachten, andererseits immer noch so teuer, dass ein Teil des Services kostenpflichtig wird, MAD Scientist Network bietet anerkannt gute Auskunft im naturwissenschaftlichen Bereich, verweist viele Fragenden auf das Archiv und hat ansonsten keine schnellen Reaktionszeiten, Wer-weiss-was vertraut auf selbsternannte Experten, es gibt also keine Qualitätssicherung, und Googles Auskunftsdienst ist kostenpflichtig und noch in der beta-Phase. Alles in allem eine Arbeit, die man zur Kenntnis nehmen sollte, um die Lösungen der Konkurrenz zu studieren, wenn man eine Online-Auskunft einführen möchte."

- Rez. in: JASIST 56(2005) no.11, S.1238-1239 (D.A. Stirling): "Virtual reference services are becoming an important tool as librarians strive to stay current with patron's information demands. In 2001, the Washington State Library initiated the Statewide Virtual Reference Project (SVRP) to support electronic reference services throughout the state. An element of that project, termed "Anytime, Anywhere Answers," was designed to train librarians in the effective use of virtual reference services. The results of that project, including precautions and pitfalls, as well as the curriculum used in the project, are recounted in this book. The book begins with a short review of the Washington State experience with virtual reference training (VRT) and the means by which the guide can be used. The very first page begins with an example of a virtual reference session gone wrong and the authors set the tone for the remainder of the book, which decries the "Shazam! You're a virtual librarian" phenomenon. The second chapter provides a thorough overview of the Washington State SVRP, including planning elements, budgeting, convening of focus groups, and training development. Perhaps the most important information in this chapter is the identification of eight key skills, aptitudes, and knowledge critical in online environments: chat skills, online reference interview, internet searching, database searching, collaborative browsing, customizing scripts, methods for evaluating success, and coping with technical glitches. Building an the aforementioned eight key skills, Chapter Three of the book examines the "core competencies" needed for virtual reference. These 14 competencies are wide ranging and clearly demanding of the librarian training in VRT. In addition, the authors expound upon the eight key skills, aptitudes, and knowledge identified in Chapter Two. Constructivist learning, which has garnered controversy in recent years, was identified as the learning platform for Washington State's SVRP and is the subject of the book's fourth chapter. The authors explain why this learning Format was chosen-primarily because VRT developers felt that participants would learn better by reaching their own conclusions. In this case, constructivist learning involved virtual field trips, secret patron activities, and weekly chat meetings. The challenge of developing the SVRP is described in Chapter Five, with a focus an descriptions of in-person training, online training, and individual and collaborative learning. While earlier chapters discuss theory, practical issues involved in developing and maintaining a VRT program are the subject of Chapters Six through Nine. Important issues, such as curriculum development, training activities, online behavior, and post-program assessment, are examined in detail. Many of the issues examined in these chapters are those that information professionals are faced with an a regular basis. In discussing curriculum development, the authors describe the important questions that need to be asked, as well as important issues such as identifying and qualifying trainers and staff, course timing, determining curriculum efficacy, methods of training delivery, and methods of evaluation.

- Rez. in: JASIST 55(2004) no.1, S.90-91 (N. Rhodes): "The recent near-exponential increase in XML-based technologies has exposed a gap between these technologies and those that are concerned with more fundamental data management issues. This very comprehensive and well-organized book has quite neatly filled the gap, thus achieving most of its stated intentions. The target audiences are database and XML professionals wishing to combine XML with modern database technologies and such is the breadth of scope of this book (hat few would not find it useful in some way. The editors have assembled a collection of chapters from a wide selection of industry heavyweights and as with most books of this type, it exhibits many disparate styles but thanks to careful editing it reads well as a cohesive whole. Certain sections have already appeared in print elsewhere and there is a deal of corporate flag-waving but nowhere does it become over-intrusive. The preface provides only the very brietest of introductions to XML but instead sets the tone for the remainder of the book. The twin terms of data- and document-centric XML (Bourret, 2003) that have achieved so much recent currency are re-iterated before XML data management issues are considered. lt is here that the book's aims are stated, mostly concerned with the approaches and features of the various available XML data management solutions. Not surprisingly, in a specialized book such as this one an introduction to XML consists of a single chapter. For issues such as syntax, DTDs and XML Schemas the reader is referred elsewhere, here, Chris Brandin provides a practical guide to achieving good grammar and style and argues convincingly for the use of XML as an information-modeling tool. Using a well-chosen and simple example, a practical guide to modeling information is developed, replete with examples of the pitfalls. This brief but illuminating chapter (incidentally available as a "taster" from the publisher's web site) notes that one of the most promising aspects of XML is that applications can be built to use a single mutable information model, obviating the need to change the application code but that good XML design is the basis of such mutability.

- Rez. in: JASIST 55(2004) no.5, S.467-468 (W. Koehler): "Virtual Inequality is an important contribution to the digital divide debate. That debate takes two basic forms. One centers an the divide between the "information rich" developed countries and the "information poor" developing countries. The second is concerned with the rift between information "haves" and "have-nots" within countries. This book addresses the latter domain and is concerned with the digital divide in the United States. This book is the product of a cross-disciplinary collaboration. Mossberger and Tolbert are both members of the Kent State University political science department while Stansbury is an the Library and Information Science faculty. The book is extremely well documented. Perhaps the chapter an the democracy divide and e-government is the best done, reflecting the political science bent of two of the authors. E-government is very well covered. Unfortunately, e-commerce and e-education go virtually unmentioned. If e-government is important to defining the digital divide, then certainly e-commerce and e-education are as well. Mossberger, Tolbert, and Stansbury argue that the digital divide should be described as four different divides: the access divide, the skills divide, the economic opportunity divide, and the democratic divide. Each of these divides is developed in its own chapter. Each chapter draws well an the existing literature. The book is valuable if for no other reason than that it provides an excellent critique of the current state of the understanding of the digital divide in the United States. It is particularly good in its contrast of the approaches taken by the Clinton and George W. Bush administrations. Perhaps this is a function of the multidisciplinary strength of the book's authorship, for indeed it shows here. The access divide is defined along "connectivity" lines: who has access to digital technologies. The authors tonfirm the conventional wisdom that age and education are important predictors of in-home access, but they also argue that rate and ethnicity are also factors (pp. 32-33): Asian Americans have greatest access followed by whites, Latinos, and African Americans in that order. Most access the Internet from home or work, followed by friends' computers, libraries, and other access points. The skills divide is defined as technical competence and information literacy (p. 38). Variation was found along technical competence for age, education, affluence, rate, and ethnicity, but not gender (p. 47). The authors conclude that for the most part the skills divide mirrors the access divide (p. 55). While they found no gender difference, they did find a gender preference for skills acquisition: males prefer a more impersonal delivery ("online help and tutorials") while females prefer more personal instruction (p. 56).
Anmerkung des Rezensenten in JASIST 55(2004) no.11, S.1024: "After reflecting an a requestfrom the authors of the reviewed book, 1 find that I did indeed err in my criticism of their methodology. The work's fault lies not with the methodology but rather with the discussion and explanation provided for the methodology. The authors do offer brief methodological explanation and justification in endnotes and appendices but are less clear in the book's text. I apologize to both the readers of the review and the authors for misinterpreting the text. For the authors' part, a methodology chapter would have been welcome. I am pleased to put right this misinterpretation that cast a shadow over an otherwise fine work."

- 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.

Scholl): "The book is based an a doctoral thesis titled "Global opportunity and national political economy: The development of internet ventures in Germany," which was supervised by Razeen Sally and accepted at the International Relations Department of the London School of Economics & Political Science, UK, in 2002. Its primary audience, although it is certainly of interest to policy makers, trade press journalists, and industry practitioners, is the academic community, and, in particular, (international) policy, business, business history, information technology, and information science scholars. The book's self-stated purpose is to explain "why Europe, despite initiating a tremendous amount of change ... failed to produce independent internet ventures of note" (p. 1) in contrast to the United States, where Internet start-ups such as Amazon.com, eBay, E*trade, and Yahoo managed to survive the notorious dot.com shakeout of 200I-2002. A few pages down, the objective is restated as "to explore the hypothesis of a global opportunity for technology innovation delivered via the internet and to explain Europe's entrepreneurial response" (p. 4). As a proxy case for Europe, the study provides a broad account of the changing legal and socioeconomic setting during the phase of early Internet adoption and development in Germany throughout the 1990s. The author highlights and details various facets of the entrepreneurial opportunity and compares the German case in some detail to corresponding developments in Sweden. Waesche concludes that starting an Internet business in Germany during that particular period of time was a "wrong country, wrong time" (p. I86) proposition.

- Rez. in: JASIST 56(2005) no.11, S.1237-1238 (E. Yakel): "This book provides the profession with a cogent, thorough, and thoughtful introduction to digital reference. Janes not only provides the breadth of coverage expected in an introduction, but also depth into this important topic. Janes' approach is managerial or administrative, providing guidelines for reference work that can be applied in different settings. Janes creates a decision-making framework to help reference librarians make decisions concerning how, to what extent, and in what cases digital reference services will be delivered. In this way, Janes avoids dictating a "one-size-fits-all" model. This approach is the major strength of the book. Library administrators and heads of reference services will find the administrative approach welcome by helping them think through which digital reference policies and methods will best target core constituencies and their institutional environments. However, the book deserves a broader audience as professors will find that the book fits nicely in a general reference course. For all readers, the book is readable and engaging and also challenging and questioning. The book begins with a history of reference work, nicely positioning digital reference in this tradition and noting the changes wrought by the digital age. By doing this, the author establishes both continuity and change in reference work as well as the values surrounding this activity. These values are largely those from the library community and Support people's access to information as well as activities that support the use of information. Janes closes this chapter by noting that the continuing changes in demographics, technology, and connectivity will impact reference work in ways that are not yet imaginable. This introduction sets the tone for the rest of the book. Janes defines digital reference service as "the use of digital technologies and resources to provide direct, professional assistance to people who are seeking information, wherever and whenever they need it" (p. 29). This definition covers a lot of ground. Examples include everything from a public library answering email queries to commercial ask-an-expert services. While the primary audience is librarians, Janes continually reminds readers that many others perform reference activities an the World Wide Web. Furthermore, he cautions readers that there are larger forces shaping this activity in the world that need to acknowledged. In building a framework for decision-making, Janes outlines the types of digital reference service. This discussion covers the communieations modes, such as e-mail, chat, Web forms, etc. It also analyzes the modalities by which reference service is delivered: synchronous/ asynchronous. Using these two dimensions (communication method and synchronous/asynchronous), Janes presents the variety of contexts in which digital reference can take place and then outlines the strengths and weaknesses of each of these. This translates into a decision-making framework by which readers analyze their particular setting and then select the modes and modalities that world be most effective. This is a powerful device and demonstrates the many options (and perhaps also the obstacles) for providing digital reference service.

Liao): "The user, without whom any product or service would be nothing, plays a very important role during the whole life cycle of products or services. The user's involvement should be from the very beginning, not just after products or services are ready to work. According to ISO 9241-11: 1998, Part 11, Usability refers to "the extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of user." As an academic topic of human-computer interaction, Web usability has been studied widely for a long time. This classroom-oriented book, bridging academia and the educational community, talks about Web usability in a student-friendly fashion. It outlines not only the methodology of user-centered Web site design but also details the methods to implement at every stage of the methodology. That is, the book presents the user-centered Web-design approach from both macrocosm and microcosm points of view, which makes it both recapitulative and practical. The most important key word in Web Usability is "user-centered," which means Web developers should not substitute their own personal preferences for the users' needs. The book classifies Web sites into five types: E-commerce, informational, entertainment, community, and intranet. Since the methods used during Web development differ somewhat depending on the type of Web site, it is necessary to have a classification in advance. With Figure 1.3 on p. 17, the book explains the whole user-centered Webdevelopment life cycle (called "methodology" in this book review), which provides a clear path for Web development that is easy to understand, remember, and perform. Since all the following chapters are based on the methodology, a clear presentation of it is paramount. The table on p. 93 summarizes concisely all types of methods for requirements gathering and their advantages and disadvantages. According to this table, appropriate methods can be easily chosen for different Web site development projects. As the author remarked, "requirements gathering is central to the concept of user-centered design," (p. 98) and "one of the hallmarks of user-centered design is usability testing" (p. 205). Stage 2 (collect user requirements) and Stage 5 (perform usability testing) of the user-centered Web-development life cycle are the two stages with the most user involvement: however, this does not mean that all other stages are user unrelated. For example, in Stage 4 (create and modify physical design), frame is not suggested to be used just because most users are unfamiliar with the concept of frame (p. 201). Note that frequently there are several rounds of usability testing to be performed in the four case studies, and some of them are performed before the physical-design stage or even the conceptual-design stage, which embodies the idea of an iterative design process.

- Rez. in: JASIST 58(2007) no.4, S.608-609 (K.D. Desouza): "Richard Rogers explores the distinctiveness of the World Wide Web as a politically contested space where information searchers may encounter multiple explanations of reality. Sources of information on the Web are in constant competition with each other for attention. The attention a source receives will determine its prominence, the ability to be a provider of leading information, and its inclusion in authoritative spaces. Rogers explores the politics behind evaluating sources that are collected and housed on authoritative spaces. Information politics on the Web can be looked at in terms of frontend or back-end politics. Front-end politics is concerned with whether sources on the Web pay attention to principles of inclusivity, fairness, and scope of representation in how information is presented, while back-end politics examines the logic behind how search engines or portals select and index information. Concerning front-end politics, Rogers questions the various versions of reality one can derive from examining information on the Web, especially when issues of information inclusivity and scope of representation are toiled with. In addition, Rogers is concerned with how back-end politics are being controlled by dominant forces of the market (i.e., the more an organization is willing to pay, the greater will be the site's visibility and prominence in authoritative spaces), regardless of whether the information presented on the site justifies such a placement. In the book, Rogers illustrates the issues involved in back-end and front-end politics (though heavily slanted on front-end politics) using vivid cases, all of which are derived from his own research. The main thrust is the exploration of how various "information instruments," defined as "a digital and analytical means of recording (capturing) and subsequently reading indications of states of defined information streams (p. 19)," help capture the politics of the Web. Rogers employs four specific instruments (Lay Decision Support System, Issue Barometer, Web Issue Index of Civil Society, and Election Issue Tracker), which are covered in detail in core chapters of the book (Chapter 2-Chapter 5). The book is comprised of six chapters, with Chapter 1 being the traditional introduction and Chapter 6 being a summary of the major concepts discussed.
