    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.

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

    Abstract
    The emergence of information portal systems in the past few years has led to a greatly enhanced Web-based environment for users seeking information online. While considerable research has been conducted an user information-seeking behavior in regular IR environments over the past decade, this paper focuses specifically an how users in a medical science and clinical setting carry out their daily information seeking through a customizable information portal system (MyWelch). We describe our initial study an analyzing Web usage data from MyWelch to see whether the results conform to the features and patterns established in current information-seeking models, present several observations regarding user information-seeking behavior in a portal environment, outline possible long-term user information-seeking patterns based an usage data, and discuss the direction of future research an user information-seeking behavior in the MyWelch portal environment.

    Abstract
    Reading is a common everyday activity for most of us. In this article, we examine the potential for using Wikipedia to fill in the gaps in one's own knowledge that may be encountered while reading. If gaps are encountered frequently while reading, then this may detract from the reader's final understanding of the given document. Our goal is to increase access to explanatory text for readers by retrieving a single Wikipedia article that is related to a text passage that has been highlighted. This approach differs from traditional search methods where the users formulate search queries and review lists of possibly relevant results. This explicit search activity can be disruptive to reading. Our approach is to minimize the user interaction involved in finding related information by removing explicit query formulation and providing a single relevant result. To evaluate the feasibility of this approach, we first examined the effectiveness of three contextual algorithms for retrieval. To evaluate the effectiveness for readers, we then developed a functional prototype that uses the text of the abstract being read as context and retrieves a single relevant Wikipedia article in response to a passage the user has highlighted. We conducted a small user study where participants were allowed to use the prototype while reading abstracts. The results from this initial study indicate that users found the prototype easy to use and that using the prototype significantly improved their stated understanding and confidence in that understanding of the academic abstracts they read.

    Abstract
    Reports a preliminary analysis of organizational schemes applied by academic libraries worldwide to arrange their electronic resources an their Web-based information gateways. The unsystematic sample consists of 41 academic libraries in 10 countries representing 4 languages, Chinese, English, German, and Spanish. The study reveals a widely accepted practice in applying 6 simplistic methods to organizing online information: by resource type, alphabetical by title, alphabetical by subject (mostly discipline and genre), by vendor/publisher, by broad classification, and random. In addition, it notes a marked difference between libraries in the English-speaking world and those in other countries in that the former present significantly more systematic characteristics.

    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.

    Abstract
    As more people gain at-home access to the Internet, information seeking an the Web has become embedded in everyday life. The objective of this study was to characterize the home as an information use environment and to identify a range of information seeking and Websearch behaviors at home. Twelve Northern California residents were recruited, and the data were collected through semi-structured at-home interviews based an a self-reported Search Activities Diary that subjects kept over a 3-5 day period. The data were analyzed an four levels: home environment, information seeking goals, information retrieval interaction, and search query. Eindings indicated that the home, indeed, provided a distinct information use environment beyond physical setting alone in which the subjects used the Web for diverse purposes and interests. Based an the findings, the relationships among home environment, Web context, and interaction situation were identified with respect to user goals and information-seeking behaviors.

    Abstract
    The Wikipedia is a collaborative encyclopedia: anyone can contribute to its articles simply by clicking on an "edit'' button. The open nature of the Wikipedia has been key to its success, but has a flip side: if anyone can edit, how can readers know whether to trust its content? To help answer this question, we have developed a reputation system for Wikipedia authors, and a trust system for Wikipedia text. Authors gain reputation when their contributions are long-lived, and they lose reputation when their contributions are undone in short order. Each word in the Wikipedia is assigned a value of trust that depends on the reputation of its author, as well as on the reputation of the authors that subsequently revised the text where the word appears. To validate our algorithms, we show that reputation and trust have good predictive value: higher-reputation authors are more likely to give lasting contributions, and higher-trust text is less likely to be edited. The trust can be visualized via an intuitive coloring of the text background. The coloring provides an effective way of spotting attempts to tamper with Wikipedia information. A trust-colored version of the entire English Wikipedia can be browsed at http://trust.cse.ucsc.edu/

    Abstract
    SFX is an XML-based product designed to inter-link electronic resources with other resources in context-sensitive manner. SFX was first developed at the University of Ghent by Herbert Van de Sompel and has been released as a commercial product by Ex Libris. Use statistics garnered from SFX's statistics module since the implementation in July of 2001 are discussed in the context of an academic research library environment. The results from usability testing conducted at Washington State University are reported. These usage statistics demonstrated a pattern of increasing use and exceptional use from FirstSearch databases.

    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
    More than 100 U.S. governmental agencies offer links through FedStats, a centralized Web site that facilitates access to statistical tables, reports, and agencies. This and similar large collections need appropriate interfaces to guide the general public to easily and successfully find information they seek. This paper summarizes the results of 3 empirical studies of alternate organization concepts of the FedStats Topics Web page. Each study had 15 participants. The evolution from 645 alphabetically organized links, to 549 categorically organized links, to 215 categorically organized links tied to portal pages produced a steady rise in successful task completion from 15.6 to 24.4 to 42.2%. User satisfaction also increased. We make recommendations based an these data and our observations of users.

    Abstract
    By Internet resources Zhang means any electronic file accessible by any Internet protocol. Their usage is determined by an examination of the citations to such sources in a nine-year sample of four print and four electronic LIS journals, by a survey of editors of these journals, and by a survey of scholars with "in press" papers in these journals. Citations were gathered from Social Science Citation Index and manually classed as e-sources by the format used. All authors with "in press" papers were asked about their use and opinion of Internet sources and for any suggestions for improvement. Use of electronic sources is heavy and access is very high. Access and ability explain most usage while satisfaction was not significant. Citation of e-journals increases over the eight years. Authors report under citation of e-journals in favor of print equivalents. Traditional reasons are given for citing and not citing, but additional reasons are also present for e-journals.
