    Abstract
    For many years metadata has been recognised as a significant component of the digital information environment. Substantial work has gone into creating complex metadata schemes for describing digital content. Yet increasingly Web search engines, and Google in particular, are the primary means of discovering and selecting digital resources, although they make little use of metadata. This article considers how digital libraries can gain more value from their metadata by adapting it for Google users, while still following well-established principles and standards for cataloguing and digital preservation.

    Abstract
    The hbz (Academic Library Center, Cologne) has a strong focus on search engine applications: Beyond the projected integration of respective technologies into the new release of the Digital Library portal solution (DigiBib6), vascoda background services also apply and take advantage of search engine technology. Experience since 2003 has given proof that building and updating of search engine indexes involves a vast amount of resources. The use of search engine federations, however, pledges major improvements: The total amount of data records held in linked indexes can be almost unlimited but also allow for a joint output of all hits retrieved. A federation also comes with excellent response times - hits retrieved can also refer to or link into the original system's layout. Nonetheless, the major challenge these days is different search engine technologies, e.g. Lucene and FAST, the variations in terms of ranking, and the implementation or non-implementation of so-called drill-downs. The lecture is designed to give a brief insight into the hbz search engine workshop with an introduction to the special project state of play.

    Abstract
    This article describes the journey from the conception of and vision for a modern search-engine-based search environment to its technological realisation. In doing so, it takes up the thread of an earlier article on this subject, this time from a technical viewpoint. As well as presenting the conceptual considerations of the initial stages, this article will principally elucidate the technological aspects of this journey. The starting point for the deliberations about development of an academic search engine was the experience we gained through the generally successful project "Digital Library NRW", in which from 1998 to 2000-with Bielefeld University Library in overall charge-we designed a system model for an Internet-based library portal with an improved academic search environment at its core. At the heart of this system was a metasearch with an availability function, to which we added a user interface integrating all relevant source material for study and research. The deficiencies of this approach were felt soon after the system was launched in June 2001. There were problems with the stability and performance of the database retrieval system, with the integration of full-text documents and Internet pages, and with acceptance by users, because users are increasingly performing the searches themselves using search engines rather than going to the library for help in doing searches. Since a long list of problems are also encountered using commercial search engines for academic use (in particular the retrieval of academic information and long-term availability), the idea was born for a search engine configured specifically for academic use. We also hoped that with one single access point founded on improved search engine technology, we could access the heterogeneous academic resources of subject-based bibliographic databases, catalogues, electronic newspapers, document servers and academic web pages.

    Abstract
    One finding of the 2006 OCLC study of College Students' Perceptions of Libraries and Information Resources was that students expressed equal levels of trust in libraries and search engines when it came to meeting their information needs in a way that they felt was authoritative. Seeking to incorporate this insight into our own instructional methodology, Schaffer Library at Union College has attempted to engineer a shift from Google to Google Scholar among our student users by representing Scholar as a viable adjunct to the catalog and to snore traditional electronic resources. By attempting to engage student researchers on their own terms, we have discovered that most of them react enthusiastically to the revelation that the Google they think they know so well is, it turns out, a multifaceted resource that is capable of delivering the sort of scholarly information that will meet with their professors' approval. Specifically, this article focuses on the fact that many Google Scholar searches link hack to our own Web catalog where they identify useful book titles that direct OPAC keyword searches have missed.

    Abstract
    Purpose - This article is an edited version of a report commissioned by the British Library and JISC to identify how the specialist researchers of the future (those born after 1993) are likely to access and interact with digital resources in five to ten years' time. The purpose is to investigate the impact of digital transition on the information behaviour of the Google Generation and to guide library and information services to anticipate and react to any new or emerging behaviours in the most effective way. Design/methodology/approach - The study was virtually longitudinal and is based on a number of extensive reviews of related literature, survey data mining and a deep log analysis of a British Library and a JISC web site intended for younger people. Findings - The study shows that much of the impact of ICTs on the young has been overestimated. The study claims that although young people demonstrate an apparent ease and familiarity with computers, they rely heavily on search engines, view rather than read and do not possess the critical and analytical skills to assess the information that they find on the web. Originality/value - The paper reports on a study that overturns the common assumption that the "Google generation" is the most web-literate.

    Footnote
    ... This book is written by library professionals and aimed at the librarians in particular, but it will be useful to others who may be interested in knowing what libraries are up to in the age of Google. It is intended for library science educators and students, library administrators, publishers and university presses. It is well organized, well researched, and easily readable. Article titles are descriptive, allowing the reader to find what he needs by scanning the table of contents or by consulting the index. The only flaw in this book is the lack of summary or conclusions in a few articles. The book is in paperback and has 240 pages. This book is a significant contribution and I highly recommend it."

    Abstract
    Project SSG-FI at SUB Göttingen provides special subject gateways to international high quality Internet resources for scientific users. Internet sites are selected by subject specialists and described using an extension of qualified Dublin Core metadata. A basic evaluation is added. These descriptions are freely available and can be searched and browsed. These are now subject gateways for 3 subject ares: earth sciences (GeoGuide); mathematics (MathGuide); and Anglo-American culture (split into HistoryGuide and AnglistikGuide). Together they receive about 3.300 'hard' requests per day, thus reaching over 1 million requests per year. The project SSG-FI behind these guides is open to collaboration. Institutions and private persons wishing to contribute can notify the SSG-FI team or send full data sets. Regular contributors can request registration with the project to access the database via the Internet and create and edit records

    Abstract
    DAFFODIL is a search system for digital libraries aiming at strategic support during the information search process. From a user point of view this strategic support is mainly implemented by high-level search functions, so-called stratagems, which provide functionality beyond today's digital libraries. Through the tight integration of stratagems and with the federation of heterogeneous digital libraries, DAFFODIL reaches high effects of synergy for information and services. These effects provide high-quality metadata for the searcher through an intuitively controllable user interface. The implementation of stratagems follows a tool-based model.

    Abstract
    Traditional on-line search services such as Dialog, DataStar and Lexis provide a wide range of search features (boolean and proximity operators, truncation, etc). This paper discusses the use of these features for effective searching, and argues that these features are required, regardless of advances in search engine technology. The literature on on-line searching is reviewed, identifying features that searchers find desirable for effective searching. A selective survey of current digital libraries available on the Web was undertaken, identifying which search features are present. The survey indicates that current digital libraries do not implement a wide range of search features. For instance: under half of the examples included controlled vocabulary, under half had proximity searching, only one enabled browsing of term indexes, and none of the digital libraries enable searchers to refine an initial search. Suggestions are made for enhancing the search effectiveness of digital libraries; for instance, by providing a full range of search operators, enabling browsing of search terms, enhancement of records with controlled vocabulary, enabling the refining of initial searches, etc.

    Abstract
    The dominant method currently used to improve the quality of Internet search systems is often called "digital democracy." Such an approach implies the utilization of the majority opinion of Internet users to determine the most relevant documents: for example, citation index usage for sorting of search results (google.com) or an enrichment of a query with terms that are asked frequently in relation with the query's theme. "Digital democracy" is an effective instrument in many cases, but it has an unavoidable shortcoming, which is a matter of principle: the average intellectual and cultural level of Internet users is very low- everyone knows what kind of information is dominant in Internet query statistics. Therefore, when one searches the Internet by means of "digital democracy" systems, one gets answers that reflect an underlying assumption that the user's mind potential is very low, and that his cultural interests are not demanding. Thus, it is more correct to use the term "digital ochlocracy" to refer to Internet search systems with "digital democracy." Based an the well-known mathematical mechanism of linear programming, we propose a method to solve the indicated problem.

    Abstract
    This article gives an overview of the design and organisation of DutchESS, a Dutch information subject gateway created as a national collaborative effort of the National Library and a number of academic libraries. The combined centralised and distributed model of DutchESS is discussed, as well as its selection policy, its metadata format, classification scheme and retrieval options. Also some options for future collaboration on an international level are explored

    "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.
    "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."

    "Es soll der "Airbus von morgen" werden. Mit diesen Worten hat Frankreichs Staatspräsident Jacques Chirac das deutsch-französische Projekt einer gemeinsamen europäischen Suchmaschine angekündigt, mit der man dem US-Riesen Google Konkurrenz machen will. Das deutsch-französische Kind wurde Quaero getauft. Kein ganz einfacher Name für ein Produkt, das einen weltweiten Marktführer verdrängen soll, der so allgegenwärtig und dominant ist, dass der Begriff "googeln" längst in unsere Sprache Eingang gefunden hat und im Duden verzeichnet ist. Quaero heißt auf Lateinisch "Ich suche". Das klingt nach europäischem Bildengsdünkel und spiegelt zudem den gegenwärtigen Zustand des Projektes gut wider. Gesucht wurde in Deutschland lange nach kompetenten Industriepartnern und gemeinsam mit den Franzosen nach einer Technologie, welche die Möglichkeiten einer herkömmlichen Recherche, wie man sie bei Google, Yahoo oder MSN Search machen kann, bei weitem überschreiten würde. Denn anstatt mittels bestimmter Suchbegriffe bloß Texte im Netz aufzuspüren, soll Quaero eine multimediale Suchmaschine werden, die auch Bilder, Filme und Audiodateien aufspürt. Die Quaero-Initiative ist Teil von Frankreichs Kampf gegen amerikanische Kulturhegonomie. Mit Googles Ankündigung, bis 2015 rund 15 Millionen Bücher zu digitalisieren und über "Google Print" online zugänglich zu machen, begann der Widerstand. Wortführer des Protestes und Initiator ist Jean-Noel Jeanneney, Direktor der französischen Nationalbibliothek. Sollte das literarische Erbe Europas von einem US-Konzern digital verwaltet werden, so Jeanneneys Begründung, drohe eine Hierarchisierung und Ordnung des Wissens nach rein kommerziellen Gesichtspunkten und aus einer einzig amerikanischen Perspektive. Neben den Marktführern Google, Yahoo und MSN Search, die 90 Prozent Marktanteil haben, existieren viele weitere Suchmaschinen im Internet. Auch das Portal Accoona.eu, das in sieben EU-Sprachen arbeitet, will Google Konkurrenz machen. Aber selbst Branchenriesen scheitern daran seit Jahren. Google investiert 400 Millionen Dollar jährlich in Forschung und Entwicklung. Bislang sucht der Internetnutzer vergeblich nach Quaero. Wer sich ein erstes Bild machen will, landet auf der Webseite einer amerikanischen Firma. Der Domainname Quaero.com ist nämlich schon vergeben. Quaero.org ist bislang passwortgeschützt. Sollte sich Quaero tatsächlich als der "Airbus von morgen" erweisen, könnte auch diesem deutsch-französischen Projekt schnell der Absturz drohen."

    If Babel symbolized our incommensurate ambition, the Library of Alexandria showed how this Ambition might be achieved. Set up by Ptolemy I in the third century B.C., it was meant to hold every book an every imaginable subject. To ensure that no title escaped its vast catalog. a royal decree ordered that any book brought into the City was to be confiscated and copied; only then would the original (sometimes the copy) be returned. A curious document from the second century B.C., the perhaps apocryphal "Letter of Aristeas," recounts the library's origins. To assemble a universal library (says the letter), King Ptolemy wrote "to all the sovereigns and governors an earth" begging them to send to him every kind of book by every kind of author, "poets and prose writers, rhetoricians and sophists, doctors and soothsayers, historians and all others, too." The king's librarians calculated that they required 500.000 scrolls if they were to collect in Alexandria "all the books of all the peoples of the world." But even this (by our standards) modest stock of a half-million books was too much for any reader. The librarians of Alexandria devised a system of annotated catalogs for which they chose works, they deemed especially important, and appended a brief description to each title - one of the earliest "recommended reading" lists. In Alexandria, it became clear that the greater your ambition, the narrower your scope. But our ambition persists recently, the most popular Internet search service. Google, announced that it had concluded agreements with several leading research libraries to make some of their books available online to researchers.
    The practical arguments for such a step are irrefutable: quantity, speed, precision, on-demand availability are no doubt important to the scholar: And new technologies need not be exclusionary. The invention of photography did not eliminate painting, it renewed it, and no doubt the screen and the reference books can feed oft Bach other and coexist amicably an the same reader's desk. All we need to do is remember the corollaries tethe arguments in favor of a virtual library:" that reading, in orderto allow reflection, requires slowness, depth and context; that leafing through a material book or roaming through material shelves is an intimate part of the craft; that the omnipresent electronic technology is still fragile and that, as it changes. we keep losing the possibility of retrieving that which was once stored in now outdated containers. We can still read the words an papyrus ashes saved from the charred ruins of Pompeii; we don't know for how lung it will be possible to read a text inscribed in a 2004 CD. This is not a complaint just a reminder. Jorge Luis Berges invented a Bouvard-and-Pécuchet-like charafter who tries to compile a universal encyclopedia so complete that nothing world be excluded from it. In the end, like his French forerunners, he falls. but not entirely. On the evening an which he gives up bis great project. he hires. a horse and buggy and takes a tour of the city. He sees brick walls, ordinary people. houses, a river, a marketplace and feels that somehow all these things are his own work. He realizes that his project was not impossible but merely redundant. The world encyclopedia, the universal library, already exists and is the world itself."
