    Abstract
    The creation of services linking related information entities is an area that is attracting an ever increasing interest in the ongoing development of the World Wide Web in general, and of research-related information systems in particular. Currently, both practice and theory point at linking services as being a major domain for innovation enabled by digital communication of content. Publishers, subscription agents, researchers and libraries are all looking into ways to create added value by linking related information entities, as such presenting the information within a broader context estimated to be relevant to the users of the information. This is the first of two articles in D-Lib Magazine on this topic. This first part describes the current state-of-the-art and contrasts various approaches to the problem. It identifies static and dynamic linking solutions as well as open and closed linking frameworks. It also includes an extensive bibliography. The second part, SFX, a Generic Linking Solution describes a system that we have developed for linking in a hybrid working environment. The creation of services linking related information entities is an area that is attracting an ever increasing interest in the ongoing development of the World Wide Web in general, and of research-related information systems in particular. Although most writings on electronic scientific communication have touted other benefits, such as the increase in communication speed, the possibility to exchange multimedia content and the absence of limitations on the length of research papers, currently both practice and theory point at linking services as being a major opportunity for improved communication of content. Publishers, subscription agents, researchers and libraries are all looking into ways to create added-value by linking related information entities, as such presenting the information within a broader context estimated to be relevant to the users of the information.

    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
    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.

    Der neue Herausgeber des Brockhaus, ein Tochterverlag von Bertelsmann, hat unterdessen angekündigt, zum gedruckten Lexikon zurückzukehren. Etwa Anfang 2015 soll die 22. Auflage erscheinen. In Zeiten des virtuellen Informationsoverkills gebe es einen Bedarf an Orientierung, an Relevanzvorgaben, sagt Geschäftsführer Christoph Hünermann. Ausgerechnet Bertelsmann druckte 2008 ein knapp 1 000 Seiten langes Wikipedia-Lexikon mit den 50 000 meist gesuchten Begriffen. Eine Experten-Redaktion überprüfte die Einträge sicherheitshalber zuvor - soll allerdings kaum Fehler gefunden haben."

    Abstract
    Ähnlich spektakulär und informativ präsentieren sich auch die Astronomen: Ihr schier unerschöpflicher Fundus von Bildern und Filmen macht das "elektronische Universum" auf http://zebu.uoregon.edu ebenso einen Klick wert wie die Geschichte von "Geburt und Tod der Sterne" auf demselben Server (http://zebu.uoregon.edu/~js/astl22). Schnell gerät der Wissensdurstige auf reizvolle Seitenpfade, denn viele Vorlesungen glänzen mit sorgfältig zusammengestellten Linklisten. Die führen zum Beispiel zu den "Chemischen Briefen" Justus von Liebigs, wie sie im 19. Jahrhundert zunächst als Wissenschaftskolumne in der Augsburger Allgemeinen Zeitung erschienen (www.liebig-museum.de/chbriefe/homepage.htm). Selbst die Alchemie - neunzig ansprechend präsentierte Megabyte auf www.alchemywebsite. com - verleitet zum Verweilen. Historisches ist, weil nicht stets aktualisierungsbedürftig, ohnehin beliebt im Netz. So wartet etwa die Universität Groningen (Niederlande) mit einem voluminösen Hypertext auf, praktisch ein komplettes Lehrbuch der amerikanischen Geschichte mit Texten, Essays und Präsidentenbiografien (http://odur.let.rug.nl/usanew). Noch weiter zurück in die Vergangenheit reicht eine Anthropologen-Website über den Ursprung des Menschen (www.geocities.com/Athens/Acropolis/5579/TA.html). Verspieltere Naturen werden dort zuerst fossile Schädel zuzuordnen versuchen ("Name That Skull") oder einem Anthropologiestudenten beim Wurf des Atlatl zusehen. Dieser frühe Wurfspeer machte schon den Mammuts zu schaffen und drang noch vor wenigen hundert Jahren durch die eiserne Rüstung spanischer Konquistadoren. Selbst Angewandtes bietet die World Lecture Hall. Etwa die "Geschichte der ökonomischen Denkweise" einschließlich eines 22-Minuten-"Interviews" mit Karl Marx auf www.boisestate.edu/econ/lreynol/web/het.htm. Oder Online-Sprachkurse: Wollof und Xhosa, Suaheli und Sanskrit lehrt http://www.word2word.vorn/courscad.html. Surfen allein fördert die akademische Karriere allerdings nicht unbedingt. Wer of fizielle Online-Zertifikate in Deutschland anstrebt, findet in dem Beitrag "Virtuelle Universität im Selbstversuch" (Spektrum der Wissenschaft 11/ 2001, S. 109) gute Startpunkte für das Studieren im Netz, angefangen bei - na wo wohl? - www.studieren-irre-netz.de."

    Abstract
    Das allerdings zu höchst unterschiedlichen Preisen. So kassiert Talking.net 1,94 Mark pro Minute Auskunftszeit über das Festnetz, während Clarity für Handy-Dienste 3,63 Mark verlangt. Angesichts von gegenwärtig vier Milliarden Internet-Seiten mit einem Zuwachs von sieben Millionen Seiten pro Tag, so die Schätzung des Internet-Forschungsinstituts Cyveillance, sind Orientierungsprobleme im Netz vorprogrammiert. Suchmaschinen werfen auf Schlagworteingabe oft eine Unzahl von Verweisen aus - und lassen den Suchenden ratlos. - Exotische Fragen - Das stellten auch die Marktforscher Fittkau & Maaß bei einer Online-Umfrage fest: 57 Prozent der Internetsurfer finden es schwierig, Informationen aufzuspüren, 36 Prozent haben Probleme, vorhandene Seiten im World Wide Web zu finden und über ein Fünftel konnte nicht einmal bereits besuchte Websites wiederfinden. Dabei hat die Info-Sintflut erst begonnen. Die School of Information und Management Systems der University of California in Berkeley hat herausgefunden, dass allein 1999 1,5 Exabyte (1,5 Millionen Terabyte) neuer Daten erzeugt wurden - das sind 1.500.000.000.000.000 Bücher im Umfang von rund 300 Seiten. Derzeit taxieren die Autoren Hal Varian und Peter Lyman das Volumen aller weltweit verfügbaren Informationen auf zwölf Exabyte (= zwölf Millionen Terabyte), bis 2003 werden noch mehr Informationen erzeugt werden. Das bedeutet: In etwas mehr als zwei Jahren entstehen mehr Informationen als in den letzten 300 000 Jahren zusammen. Angesichts solcher Zahlen dürften Auskunftsdiensten goldene Zeiten bevorstehen. Vor allem wenn komplizierte Fragen zum Geschäftskonzept gehören, wie es bei der Talking.net AG der Fall ist. Der Service ist erreichbar unter der Nummer 11821 und nennt sich ausdrücklich "Alles-Auskunft".
