Abstract

Little research has compared youngsters' use of CD-ROM and the Internet for information-seeking purposes. Nevertheless, the area has recently been addressed within a largely qualitative project more generally devoted to young people's information universes. Home access to the Internet was seen to be more limited than that to CD-ROM, although the former was consulted to tackle needs of a greater number of types. The strategies employed to exploit each form of information resource were essentially similar. No attempts were reported to check the credibility of any information retrieved from electronic sources. The Internet was, however, used more frequently beyond the informants' own homes than was CD-ROM. There was also greater employment of the Internet by adults acting an the youngsters' behalf. As Internet use for school purposes rose in accordance with age, that of CD-ROM declined. When youngsters themselves compared the two resources as information-seeking tools, CD-ROM software was criticized for its lack of detailed material and the Internet for the problems in locating what was desired. Project findings have implications in a range of areas, including the marketing of CD-ROM packages, research and development and practices within schools.

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

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.
The discussion of modes for digital reference world be incomplete without focusing an the technologies that support this activity. E-mail, Web forms, chat, instant messaging, and videoconferencing, as well as the call center based software, are now being adapted for use in libraries. The book discusses the technologies currently available and an the horizon to support digital reference services. While these sections of the book may not age well, they will provide us with a historical glimpse of the nascent development of such tools and how they were used at the beginning of the digital reference age. True to the emphasis an decision-making, the chapter an technology includes a list of functions that reference librarians world want in software to support digital reference. While no current applications have all of these features, this list provides librarians with some ideas concerning possible features that can be prioritized to aid in a selection process. Despite the emphasis an technology, Janes contextualizes this discussion with several significant issues relating to its implementation. These include everything from infrastructure, collaborative service standards, service design, user authentication, and user expectations. The sections an collaborative service models and service design are particularly interesting since they are both in their infancy. Readers wanting an answer or the "best" design of either institutional or collaborative digital reference service will be disappointed. However, raising these considerations is important and Janes points out how crucial these issues will be as online reference service matures. User authentication in the context of reference service is especially tricky since tensions can emerge between license agreements and the range of people who may or may not be covered by these contracts querying reference librarians. Finally, no discussion of digital reference is complete without a discussion of the possibility of 24/7 reference service and the ensuing user expectations. While Janes has no answers to the dilemmas these raise, he does alert libraries providing digital reference services to some of the realities. One is that libraries will get a broader range of questions, which could impact staff time, collection development to support these questions, and necessitate either a confirmation of priorities or a reprioritization of activities. Another reality is that the users of digital reference services may never have partaken of their services before. In fact, for libraries funded to serve a particular constituency (public libraries, academic libraries) this influx of users raises questions about levels of service, funding, and policy. Finally, in keeping with the underlying theme of values that pervades the book, Janes points out the deeper issues related to technology such as increasing ability to track users an the web. While he realizes that anonymous information about those who ask reference questions world provide reference librarians with a great deal of information to hone services and better serve constituencies, he is well aware of the dangers involved in collectiog patron information in electronic form.
Given that the Web is constantly changing, Janes turns bis focus to the future of digital reference. Topics include changes in reference practice, restructuring resource utilization, and the evolving reference interview. These are crucial dimensions of digital reference practice that require attention. The most intriguing of these is the changing nature of the interaction with the patron. The majority of digital reference takes place without physical, aural, or visual eines to gauge understanding or to sense conclusion of the interaction. While Janes provides some guidelines for both digital reference interviewing and Web forms, he honestly admits that reference interviewing in the technologically mediated environment requires additional study in both the asynchronous and particularly synchronous communication modalities. As previously noted, Janes is as concerned about developing the infrastructure for digital reference, as he is about the service itself. By infrastructure, Janes means not only the technological infrastructure, but also the people and the institution. In discussing the need for institutionalization of digital reference, he discusses (re)training reference staff, staffing models, and institutionalizing the service. The section an institutionalizing the service itself is particularly strong and presents a 10-step planning process for libraries to follow as they consider developing online services. The book ends with some final thoughts and exhortations to the readers. The author, as in the rest of the book, encourages experimentation, innovation, and risk taking. These are not characteristics that are automatically associated with librarians, but these qualities are not alien to readers either. The theme of planning and the value of connecting people with information pervade this chapter. In this closing, Janes subtly tells readers that his guidelines and proposals are just that-there is no magic bullet here. But he does argue that there has been good work done and some models that can be adopted, adapted, and improved (and then hopefully shared with others). In the end, Janes leaves readers with a feeling that there is a place for library reference service in the digital realm. Furthermore, he is convinced that the knowledge and skills of reference librarians are translatable into this arena. By focusing an the institutionalization of digital reference services, Janes is trying to get libraries to better position themselves in the virtual world, beside the commercial services and the plethora of Web-based information competing for the patrons' attention."

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.
Im umfangreichen Anhang (44 S.) sind Checklisten, Übungen und Schulungsunterlagen vor allem zur richtigen Kommunikation mit den Benutzern zu finden. Am Schluss des Buches befindet sich noch ein Stichwortverzeichnis. Beigelegt ist eine CD-ROM mit allen im Buch aufgeführten Übungen und Links, so dass man auch am Bildschirm darauf zurückgreifen bzw. sie ausdrucken kann. Hervorzuheben ist, dass das Buch als Arbeitsbuch ausgestattet ist, es gibt viel Raum für Notizen, es werden viele anschauliche Beispiele gegeben und zu jedem Kapitel werden mehrere Übungsaufgaben gestellt. Es ist ein typisches amerikanisches Einführungsbuch, das in beneidenswert anschaulicher und konsequent praktisch orientierter Art die Leserin/den Leser in ein neues Arbeitsfeld einführt, so dass man nach der Lektüre wirklich den Eindruck hat, in Stand gesetzt zu sein, einen solchen Service in professioneller Art und Weise aufbauen zu können. Vielleicht sollte noch hervorgehoben werden, dass die Autorin es verstanden hat, den Inhalt so zu gestalten, dass er ein längeres Haltbarkeitsdatum bietet: Obwohl alle grundsätzlichen Dinge abgehandelt werden, wie z.B. die Entscheidungsgrundlagen für eine Software, wird doch nie eine konkrete Software behandelt. Solche Angaben würden schnell veralten im Gegensatz zu den Kriterien, die Software beurteilen zu können. Die Autorin bemüht sich auch, Internet-Quellen aufzuführen und zu besprechen, wo man sich in diesen Fragen up to date halten kann. Ein Buch, das in die Hände all jener gehört, für welche die Einführung einer Online-Auskunft in Frage kommt. Hermann Rösch führte in seinem Artikel zum Schluss lediglich einige Universitätsbibliotheken an, welche bereits eine Online-Auskunft eingeführt haben. Werden die öffentlichen Bibliotheken einen solchen Dienst nur in kooperativer Art und Weise über die Deutsche Internetbibliothek anbieten? Hoffentlich nicht, da die Einrichtung eines Virtual Reference Desk eine hervorragende Gelegenheit darstellt, das Image der Bibliothek als Informationsvermittlungsstelle nachhaltig zu stärken und jenen Benutzern einen Zugang zur Information zu ermöglichen, welche nicht in die Bibliothek kommen. Jedenfalls gibt dieses Buch die Grundlage, das Für und Wider eines solchen Dienstes abzuwägen und im Falle einer Einrichtung auch die Schulung der betroffenen Auskunftsbibliothekarinnen/-bibliothekare auf eine solide Basis zu stellen."
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)

According to the editors, the goal of the book is "to present results of scientific research on (I) how digital information has to be designed, (2) how artifacts or systems containing digital content should maximize usability, and (3) how context can influence the nature and efficiency of digital communication" (p. 2). Contributors to this volume have a wide assortment of backgrounds in information science, classical studies, cognitive science, information systems, and organizational sciences. The editors did an excellent job in designing the book. Each chapter is unique in its theory and method. The editors successfully put these unique chapters into the life-cycle view of information: creation, use, and deployment. . . . I would highly recommend this book as a supplementary text for graduate classes in information science, especially those dealing with the design of information systems. It was a pleasure to read this book, and I believe that readers will certainly gain from the wealth of knowledge and insights contained in the volume."

"Für die "Brockhaus Enzyklopädie digital", zu der das Fraunhofer-Institut IPSI in Darmstadt wesentliche technologische Beiträge geleistet hat, erhielt der Verlag Bibliographisches Institut & F.A. Brockhaus AG (Mannheim) am 21. Mai den AKEP Award 2006. Damit zeichnet der Arbeitskreis Elektronisches Publizieren (AKEP) des VerlegerAusschusses im Börsenverein des Deutschen Buchhandels die innovativsten elektronischen Entwicklungen in Verlagen aus. "Die 'Brockhaus Enzyklopaedie digital' hebt sich von den anderen nominierten Produkten wesentlich ab und bietet durch das Zusammenspiel unterschiedlicher Informationen neue Perspektiven auf die Welt und das Wissen", begründete Arnoud de Kemp, Jury-Sprecher und Sprecher des AKEP, die Entscheidung. Das Nachschlagewerk übertreffe alle bisher erhältlichen CD-ROM- und DVD-Enzyklopädien an Umfang und Funktionalitäten. Besonders beeindruckt hat die Jury die unterschiedlichen Möglichkeiten, wie man nach Wissen suchen kann. So reagiert die Suchmaschine auf die Eingabe komplexer Fragesätze (natürlichsprachliche Suchhilfe) und stellt im dreidimensionalen Wissensraum assoziative Zusammenhänge dar. Zudem haben etliche Objekte in diesem 3D-Wissensraum ein Kontextmenü, das sie mit gleichartigen, über- oder untergeordneten anderen Objekten in Beziehung setzt. Weit über die bisher bekannten Möglichkeiten digitaler Nachschlagewerke hinaus geht nach Ansicht der Jury auch die Verknüpfung von Artikeln mit multimedialen Elementen. Die Aufgabe des Fraunhofer IPSI in diesem Projekt war es, eine Taxonomie der Lexikoneinträge zu erstellen, die die Wissensvernetzung ermöglicht. Die "Brockhaus Enzyklopädie digital" besteht aus einem USB-Stick, der alle Texte der 30-bändigen gedruckten Enzyklopädie und die notwendige Software mit allen Suchtechnologien enthält. Die Software auf dem USB-Stick ist unter MS Windows auch ohne vorangehende Installation nutzbar. Ergänzt wird das Werk durch ein OnlinePortal, welches die Inhalte weltweit betriebsunabhängig abrufbar macht. Auch 2005 war das Fraunhofer IPSI, damals mit seiner Technologie für digitale Wasserzeichen, an zwei Preisen des AKEP beteiligt."

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

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

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.

Rez. in: JASIST 57(2006) no.8, S.1130-1132 (S.R. Tompson): "The editors of This text in MIT Press' Digital Libraries and Electronic Publishing series deliberately view digital libraries (DLs) as "sociotechnical systems" - "networks of technology. information. documents, people and practices''. They allow an additional definition of "sociotechnical" as "an analytical stance that privileges neither the social nor the technological and in which neither is reducible to the other". This is an important definition, as it is the foundation of the contributors' sociological approach to digital libraries, an approach not typical of the DL literature which still focuses "largely on the technology itself". Bishop et al. have two stated goals for this volume: 1. "... to inform police and professional practice in DLs with socially grounded understanding of DLs as part of a web of social relations and practices. 2. "... to perform technically informed social analysis of phenomena of interest to social scientists that are highlighted by digital libraries. specifically issues of work, groups, and knowledge"."

It is a free, fully searchable collection of articles written by scholars, professionals, educators, and experts who collaborate and review each other's work with oversight from an International Advisory Board. The articles are written in non-technical language and are available for free, with no commercial advertising to students, educators, scholars, professionals, decision makers, as well as to the general public. The scope of the Encyclopedia of Earth is the environment of the Earth broadly defined, with particular emphasis on the interaction between society and the natural spheres of the Earth. It will be built on the integrated knowledge from economists to philosophers to span all aspects of the environment. The Encyclopedia is being built bottom-up through the use of a wiki-software that allows users to freely create and edit content. New collaborations, ideas, and entries dynamically evolve in this environment. In this way, the Encyclopedia is a constantly evolving, self-organizing, expert-reviewed, and up-to-date source of environmental information. The motivation behind the Encyclopedia of Earth is simple. Go to GoogleT and type in climate change, pesticides, nuclear power, sustainable development, or any other important environmental issue. Doing so returns millions of results, some fraction of which are authoritative. The remainder is of poor or unknown quality.
This illustrates a stark reality of the Web. There are many resources for environmental content, but there is no central repository of authoritative information that meets the needs of diverse user communities. The Encyclopedia of Earth aims to fill that niche by providing content that is both free and reliable. Still in its infancy, the EoE already is an integral part of the emerging effort to increase free and open access to trusted information on the Web. It is a trusted content source for authoritative indexes such as the Online Access to Research in the Environment Initiative, the Health InterNetwork Access to Research Initiative, the Open Education Resources Commons, Scirus, DLESE, WiserEarth, among others. Our initial Content Partners include the American Institute of Physics, the University of California Museum of Paleontology, TeacherServe®, the U.S. Geological Survey, the International Arctic Science Committee, the World Wildlife Fund, Conservation International, the Biodiversity Institute of Ontario, and the United Nations Environment Programme, to name just a few. The full partner list here can be found at <http://www.eoearth.org/article/Content_Partners>. We have a diversity of article types including standard subject articles, biographies, place-based entries, country profiles, and environmental classics. We recently launched our E-Book series, full-text, fully searchable books with internal hyperlinks to EoE articles. The eBooks include new releases by distinguished scholars as well as classics such as Walden and On the Origin of Species. Because history can be an important guide to the future, we have added an Environmental Classics section that includes such historical works as Energy from Fossil Fuels by M. King Hubbert and Undersea by Rachel Carson. Our services and features will soon be expanded. The EoE will soon be available in different languages giving a wider range of users access, users will be able to search it geographically or by a well-defined, expert created taxonomy, and teachers will be able to use the EoE to create unique curriculum for their courses.

Abstract

In this study, we attempt to evaluate the performance of the World Wide Web as an information resource in the domain of international travel. The theoretical framework underpinning our approach recognizes the contribution of models of information seeking behavior and of information systems in explaining World Wide Web usage as an information resource. Specifically, a model integrating the construct of uncertainty in information seeking and the task-technology fit model is presented. To test the integrated model, 217 travelers participated in a questionnaire-based empirical study. Our results confirm that richer (or enhanced) models are required to evaluate the broad context of World Wide Web (the Web) usage as an information resource. Use of the Web for travel tasks, for uncertainty reduction, as an information resource, and for mediation all have a significant impact an users' perception of performance, explaining 46% of the variance. Additionally, our study contributes to the testing and validation of metrics for use of the Web as an information resource in a specific domain.

Abstract

Access to previous results is of paramount importance in the scientific process. Recent progress in information management focuses on building e-infrastructures for the optimization of the research workflow, through both policy-driven and user-pulled dynamics. For decades, High Energy Physics (HEP) has pioneered innovative solutions in the field of information management and dissemination. In light of a transforming information environment, it is important to assess the current usage of information resources by researchers and HEP provides a unique test bed for this assessment. A survey of about 10% of practitioners in the field reveals usage trends and information needs. Community-based services, such as the pioneering arXiv and SPIRES systems, largely answer the need of the scientists, with a limited but increasing fraction of younger users relying on Google. Commercial services offered by publishers or database vendors are essentially unused in the field. The survey offers an insight into the most important features that users require to optimize their research workflow. These results inform the future evolution of information management in HEP and, as these researchers are traditionally early adopters of innovation in scholarly communication, can inspire developments of disciplinary repositories serving other communities.

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

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

"Das Wort "Wiki" kommt aus Hawaii und heißt schnell. Diesen Anspruch hat die Internet-Enzyklopädie Wikipedia eingelöst: In nur vier Jahren hat das kostenlose Online-Nachschlagewerk den Globus erobert. Weltweit bringt es Wikipedia in mehr als 60 Sprachen auf über zwei Millionen Einträge, allein in Deutschland haben über 10.000 Freiwillige rund 270.000 Artikel erstellt. Noch bis Sonntag will die Wiki-Gemeinde in Frankfurt, gemeinsam mit dem Vater der Enzyklopädie, Jimmy Wales, auf ihrer ersten internationalen Konferenz über Zukunft, Erfolge und Probleme sprechen. Neben Software-Fragen wird es um die Zuverlässigkeit der Artikel gehen, die von sehr unterschiedlicher Qualität sind. Wie das Bildungsportal "Bildungsklick" herausgefunden hat, enthält im Schnitt jeder Text vier Rechtschreibfehler. Dies ist auch deshalb bedenklich, weil der kostenlose Online-Dienst von und für notorisch unterfinanzierte Schulen empfohlen wird. Die Internet-Philosophie des 38-jährigen Amerikaners Wales aus Florida ist einfach: Informationen sollen für alle frei zugänglich sein, und alle Internetnutzer können bei der Enzyklopädie mitmachen. Jeder Artikel oder Eintrag kann von anderen verbessert oder erweitert werden. Dabei kann immer festgestellt werden, wie und von wem ein Artikel verändert wurde. Zur weltweiten Verbreitung seiner Idee rief Wales 2003 die Wikimedia-Stiftung ins Leben. Die deutsche Wikipedia-Community, zweitgrößte nach den USA, ist bunt. "Wir haben 13-Jährige genauso wie 80Jährige, die für uns arbeiten", sagt Kurt Jansson, der 28 Jahre alte Vorsitzende des deutschen Fördervereins. Überdurchschnittlich viele Beiträge kommen von Studenten, der Altersdurchschnitt liege bei 30 Jahren, schätzt Jansson, der Soziologie in Berlin studiert. Bei allem idealistischen Anspruch sind jedoch auch Kontrolleure nötig. In Deutschland gibt es um die 160 Administratoren, die Einträge aus dem Web entfernen können. Sie forsten die Einträge auf Fehler durch und überprüfen Fakten auf Zuruf ihrer User. Denn auf deren Mithilfe sind sie angewiesen. Immer wieder gibt es Scherzbolde, die Artikel erfinden. Dann gibt es Artikel, die wegen fehlender Substanz jeder zur Diskussion stellen, kann. Über die ständig aktualisierte Streichliste entscheidet dann einender Administratoren. Die Administratoren müssen auch eingreifen, wenn zwei Autoren zum Beispiel bei einem Artikel über einen Politiker eine private Kontroverse austragen oder PR in eigener Sache machen. Vollständig haben sie die Worterläuterungen dabei jedoch nicht im Blick. Täglich kommen auf Deutsch 400 neue Artikel dazu und 60 verschwinden wieder. Die gesamte Verwaltung von Wikipedia gemeinnützige deutsche Förderverein finanziert sich nach eigenen Angaben - wie auch die gesamte internationale Wikipedia-Bewegung - nur aus Spenden. Die Organisation betreibt auch noch anderen Projekte wie das Nachrichtenportal Wikinews."

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

The classic problem within the information quality (IQ) research and practice community has been the problem of defining IQ. It has been found repeatedly that IQ is context sensitive and cannot be described, measured, and assured with a single model. There is a need for empirical case studies of IQ work in different systems to develop a systematic knowledge that can then inform and guide the construction of context-specific IQ models. This article analyzes the organization of IQ assurance work in a large-scale, open, collaborative encyclopedia - Wikipedia. What is special about Wikipedia as a resource is that the quality discussions and processes are strongly connected to the data itself and are accessible to the general public. This openness makes it particularly easy for researchers to study a particular kind of collaborative work that is highly distributed and that has a particularly substantial focus, not just on error detection but also on error correction. We believe that the study of those evolving debates and processes and of the IQ assurance model as a whole has useful implications for the improvement of quality in other more conventional databases.

Abstract

Consumer empowerment and the role of the expert patient in their own healthcare, enabled through timely access to quality information, have emerged as significant factors in better health and lifestyle outcomes. Governments, medical researchers, healthcare providers in the public and private sector, drug companies, health consumer groups, and individuals are increasingly looking to the Internet to both access and distribute health information, communicate with each other, and form supportive or collaborative online communities. Evaluating the accuracy, provenance, authority, and reliability of Web-based health information is a major priority. The Breast Cancer Knowledge Online Portal project (BCKOnline) explored the individual and changing information and decision support needs of women with breast cancer and the issues they face when searching for relevant and reliable health information on the Internet. Its user-sensitive research design integrated multidisciplinary methods including user information-needs analysis, knowledge-domain mapping, metadata modeling, and systems-development research techniques. The main outcomes were a personalized information portal driven by a metadata repository of user-sensitive resource descriptions, the BCKOnline Metadata Schema, richer understandings of the concepts of quality, relevance, and reliability, and a user-sensitive design methodology. This article focuses on the innovative, metadata-based quality reporting feature of the BCKOnline Portal, and concludes that it is timely to consider the inclusion of quality elements in resource discovery metadata schema, especially in the health domain.
