"When Randall C. Jimerson, the president of the Society of American Archivists, heard of Google's plan to convert certain holdings at Oxford University and at some of the leading research libraries in the United States into digital files, searchable over the Web, he asked, "What are they thinking?" Mr. Jimerson had worries. Who would select the material? How would it be organized and identified to avoid mountains of excerpts taken out of context? Would Google users eventually forgo the experience of holding a book or looking at a historicaldocument? But in recent interviews, many scholars and librarians applauded the announcement by Google, the operator of the world's most popular Internet search service, to digitize some of the collections at Oxford, the University of Michigan, Stanford University, Harvard and the New York Public Library. The plan, in the words of Paul Duguid, information specialist at the University of California at Berkeley, will "blast wide open" the walls around the libraries of world-class institutions.
David Nasaw, a historian and director of the Center for the Humanities at the City University of New York's Graduate Center, said the ability to use keywords to locate books and documents could save academics traveltime and money and broaden their research. "This all captures people's imagination in a wonderful way," Said Kate Wittenberg, director of the Electronic Publishing Initiative at Columbia University. "But whether it's right or wrong is not the whole question and not the whole answer." This year Ms. Wittenberg's group completed a three-year study of research habits that included 1,233 students. The study concluded that electronic resources had become the main tool for gathering information, particularly among undergraduates. But Ms. Wittenberg does have concerns. "What I've learned is that libraries help people formulate questions as well as find answers," Ms. Wittenberg said. "Who will do that in a virtual world?" On the other hand, she Said, an enhanced databank could make it easier for students to research topics across disciplines. For example, a topic like "climate change" touches an both political science and science, she Said, and "in the physical world, the books about them are in two different buildings at Columbia." Online research could bring the two subjects together instantly. Robert Darnton, a professor of history at Princeton who is writing a book about the history of books, noted that by looking at a book's binding and paper quality, a researcher can discern much about the period in which it was published, the publisher and the intended audience.
"There may be some false consciousnesses about this breakthrough, that all learning will be at our fingertips," Mr. Darnton said of the plans to enhance Google's database. He saw room for both Google and real-world research. Libraries have already been changed by the Internet, said Paul LeClerc, president and chief executive of the New York Public Library: But libraries will still be needed to coliect and store information, he said. "TV did replace radio," Mr. LeCIerc said. "Videos and DVD's did not replace people going to the movies. It's still easier to read a book by hand than online." "The New-York Public Library Web site gets three-fourths of a billion hits a year from 200 different countries and territories, and that's with no marketing or advertising," he said. "That's the context in which this new element has to be placed." "We had 13 million reader visits last year," he continued. "We're serving a multiplicity of audiences - we serve people physically and virtually. It's an enormous contribution to human intellectual development." Many university leaders realize that for most people, information does not exist unless it is online, said Paul Courant, provost and executive vice president for academic affairs at the University of Michigan. Mr. Courant envisioned that in 20 years archives would be shared by institutions. While the world needs "tens of thousands of copies of 'To the Lighthouse,"' he said, "we don't need to have a zillion copies of some arcane monograph written by a sociologist in 1951."

"Wer wissenschaftliche Informationen und Fachliteratur sucht, kommt mit einer herkömmlichen Internet-Suchmaschine nicht weit. Auch Bibliothekskataloge und Datenbanken helfen nur begrenzt weiter, da es zu viele Anlaufstellen im Web gibt. Das Hochschulbibliothekszentrum NRW (hbz) arbeitet deshalb an der technischen Infrastrukturlösung eines gemeinsamen Suchraums. Der Suchraum fasst mithilfe modernster Suchmaschinentechnologie viele unterschiedliche Datenquellen zu einem optimierten Index zusammen, der von verschiedenen Suchanwendungen in Sekundenschnelle abgefragt werden kann. Zu den Datenbeständen des Suchraums gehören die Kataloge der deutschsprachigen Bibliotheken sowie Artikel aus den Wissenschaftszeitschriften. Hinzu kommen Abstracts, Inhaltsverzeichnisse und andere Informationen. Ergänzt wird dieser Suchindex durch einen Zugriff auf Fachdatenbanken, die zum Beispiel das vascodaProjekt zusammenträgt. Die Suchanwendungen wie beispielsweise die Portal-Lösung »DigiBib - Die Digitale Bibliothek« müssen nur noch den einheitlich aufgebauten Index durchsuchen und erhalten die Ergebnisse nach wenigen Millisekunden. In der Realität existiert eine solche virtuelle Metabibliothek nur in den Anfängen. Der Dreiländerkatalog des hbz und das Wissenschaftsportal vascoda sind ein großer Schritt auf dem Weg zu diesem gemeinsamen Suchraum. Er kann nur durch eine - inhaltlich und geografisch-weiträumige Kooperation der Universitäten, Bibliotheken, Verlage und anderer Anbieter von Fachinformationen der deutschsprachigen Länder aufgebaut werden. Die Grundlagen für dieses Ziel wurden bereits vom hbz gelegt. Die Teilnahme am Suchraum ist eine lohnende Aufgabe für die Bibliotheken und Wissenschaftsorganisationen: Am Ende steht eine wissenschaftliche Suchmaschine, die alle wichtigen und nützlichen Datenquellen erfasst."

Abstract

Information subject gateways provide targeted discovery services for their users, giving access to Web resources selected according to quality and subject coverage criteria. Information gateways recognise that they must collaborate on a wide range of issues relating to content to ensure continued success. This report is informed by discussion of content activities at the 1999 Imesh Workshop. The author considers the implications for subject based gateways of co-operation regarding coverage policy, creation of metadata, and provision of searching and browsing across services. Other possibilities for co-operation include working more closely with information providers, and diclosure of information in joint metadata registries

Abstract

Amid the rapid growth of information today is the increasing challenge for people to navigate its magnitude. Dynamics and heterogeneity of large information spaces such as the Web raise important questions about information retrieval in these environments. Collection of all information in advance and centralization of IR operations are extremely difficult, if not impossible, because systems are dynamic and information is distributed. The chapter discusses some of the key issues facing classic information retrieval models and presents a decentralized, organic view of information systems pertaining to search in large scale networks. It focuses on the impact of network structure on search performance and discusses a phenomenon we refer to as the Clustering Paradox, in which the topology of interconnected systems imposes a scalability limit.

Abstract

The study sets out to explore the factors that influence the evaluation of information and the judgments made in the process of finding useful information in web search contexts. Based on a diary study of 2 assigned tasks to search on Google and Google Scholar, factor analysis identified the core constructs of content, relevance, scope, and style, as well as informational and system "ease of use" as influencing the judgment that useful information had been found. Differences were found in the participants' evaluation of information across the search tasks on Google and on Google Scholar when identified by the factors related to both content and ease of use. The findings from this study suggest how searchers might critically evaluate information, and the study identifies a relation between the user's involvement in the information interaction and the influences of the perceived system ease of use and information design.

Abstract

Presents a view of portal sites as a radically different model from those currently embraced by traditional information companies. The concept of a portal as a starting point that Web users pass through is an uncomfortable one for most traditional services, which are designed to be one-stop destinations for information. It will become increasingly difficult for even the largest data warehouses to compete with the rising volume of Web content if closed end information models are not abandoned in favour of distributed ones which better reflect the reality of what is available to information consumers. Dow Jones Interactive Publishing is among the first to embrace a distributed model by indexing the sites which it believes have customer value, regardless of whether they offer their content on the subscriber service
