    "Wer etwas sucht in den Weiten des Datennetzes und die genaue Adresse nicht kennt, der benutzt eine Suchmaschine. Ganz oben auf der Beliebtheitsskala steht dabei nach wie vor Google, für Deutschsprachige zu finden unter www.google.de. Gründe für die Popularität des zum Multi-MilliardenDollar-Unternehmen gewachsenen Studentenprojekts gibt es viele: Pragmatiker schwören einfach auf die guten Suchergebnisse, Freaks schätzen die "bells and whistles", das Drumherum, das die Suche komfortabel macht: - Für halbwegs Eindeutiges gelangt man kinderleicht ans Ziel: Die Suchbegriffe "Motor" und "Sport" fördern nur Dokumente zu Tage, die beide Stichworte enthalten. Ganz oben werden dabei die Seiten angezeigt, in denen beide Begriffe im Text direkt hintereinander stehen. Faustregel: Je mehr Begriffe Sie angeben, desto genauer sind hinterher die angezeigten Treffer. - Trickreicher wird es, wenn die Suchbegriffe nicht so eindeutig sind. Wer zum Beispiel etwas zu Hamlets berühmtester Textzeile sucht, sollte Anführungszeichen um den Suchbegriff verwenden: "Sein oder nicht sein" liefert nur die Dokumente, in denen die Begriffe exakt in dieser Schreibweise und Reihenfolge enthalten sind. Ergänzen Sie noch "hamlet" als zusätzlichen Suchbegriff (außerhalb der Anführungszeichen), werden die Seiten noch ergiebiger. - Sie erhalten völlig falsche Suchergebnisse, weil die Stichworte eine Doppelbedeutung haben? Ausschluss-Wörter sind die Lösung. Suchen Sie beispielsweise etwas zu Phaeton und denken dabei an das Automodell, aber sicher nicht an griechische Götter und Legenden? Verwenden Sie phaeton-auto-car-vw als Suche, um alle Seiten zu ignorieren, in denen es um dass falsche Thema geht; - Schwierig kann es auch werden, wenn Ihr Such-Stichwort dummerweise zu allgemein ist. Die Gerätebezeichnung is 380 (ein Kopfhörermodell) wird von Google nur mit der Meldung "'is' ist ein sehr häufiges Wort und wurde in der Suchanfrage ignoriert" quittiert. Abhilfe schafft die Suche mit "+is 380". - Sollen die Ergebnisse auf eine bestimmte Webseite oder Region begrenzt werden, kann ein weiterer Parameter helfen: "windows site:tippscout.de" liefert alle Seiten zum Thema Windows, aber eben nur von www.tippscout.de. Analog begrenzt "site:br" die Suche auf Seiten aus Brasilien, "-site:de" schließt deutsche Seiten von der Suche aus. - Sie interessieren sich fürs Grundgesetz, wollen aber keine seitenlangen Diskussionen, sondern nur das Dokument selbst lesen? Geben Sie den Dateityp an: "grundgesetz filetype:pdf° liefert das Gewünschte. Ebenso funktionieren natürlich doc, xls, jpg und andere Dateiarten. - Neben der Suchfunktion bietet Google noch etliche weitere Extras: Geben Sie doch einfach einmal Ihre Postleitzahl als Suchbegriff an. Google liefert den Link zu einem Stadtplan als Ergebnis.

    Abstract
    Finding information an the Internet and the World Wide Web (WWW) has always been somewhat like trying to find a needle in a haystack. An added dimension to the haystack metaphor is that the Internet environment is a dynamic collection of information. Changes occur almost every second. New pages are added. Old pages are deleted or altered. From the very beginning of the World Wide Web (WWW), search tools were needed to create order and provide an interface that allowed users to retrieve current documents while at the same time deleting inactive sites. Search databases and indexes could not be static; neither could the interface that served as the public relations instrument for the product. The tools of Internet searching emerged from the simple and modest beginnings of research and graduate school projects to the highly competitive and highly secretive proprietary corporate environment. As search tools evolved, they changed not only how people find information, but also how they viewed the world of the twenty-first century. The Internet grew out of a need to connect computers at one location to computers at other locations, thus creating a globalization of shared resources. The early iterations of shared data were basic but grew rapidly as more and more computers became connected. Connectivity led to an information base that multiplied and evolved exponentially. This information base ultimately became unwieldy, and some of the early Internet pioneers began to see the necessity for both an organizational scheme and a method for accessing what was available. Each new tool provided more order, and in general an improved searching mechanism. From the early beginnings of Telnet, File Transfer Protocol (FTP), Archie, Veronica, and Gopher to the current iterations of Web search engines and search directories that use graphical interfaces, spiders, worms, robots, complex algorithms, proprietary information, competing interfaces, and advertising, access to the vast store of materials that is the Internet has depended upon search tools.

    Abstract
    Creates an open, metadata aware system for distributed, collaborative WWW indexing. The system has 3 main components: a harvester (for collecting information), a database (for making the collection searchable), and a user interface (for making the information available). all components can be distributed across networked computers, thus supporting scalability. The system is metadata aware and thus allows searches on several fields including title, document author and URL. Nordic Web Index (NWI) is an application using this system to create a regional Nordic Web-indexing service. NWI is built using 5 collaborating service points within the Nordic countries. The NWI databases can be used to build additional services

    Abstract
    Google will in diesen Tagen im Rahmen eines Zehn-Jahres-Projektes mit dem Scannen von 15 Millionen Büchern von der Oxford University, Harvard University, Stanford University, der University of Michigan und der New York Public Library beginnen. Die Bücher, bei denen alle Copyrights erloschen sind, werden vollständig online gebracht. Aus den anderen Büchern sollen Auszüge offeriert werden. Password-Partner David Worlock (London) kommentierte den Sprung von Google in die gedruckte Welt: "More than anything, the acceleration of Google's engagement with the analog, printed world represents a decisive moment in the evolution of information publishing- toward providing "solutions" rather than the passive information assets that Google may be an the way to providing as a content utility. As its strategy unfolds, and its competitors respond, muck of the still substantially offline world of publishers, booksellers, and institutional collections, will see a year of changed assumptions and dissolving boundaries."

    Abstract
    How do you find your way in an age of information overload? How can you filter streams of complex information to pull out only what you want? Why does it matter how information is structured when Google seems to magically bring up the right answer to your questions? What does it mean to be "findable" in this day and age? This eye-opening new book examines the convergence of information and connectivity. Written by Peter Morville, author of the groundbreakin Information Architecture for the World Wide Web, the book defines our current age as a state of unlimited findability. In other words, anyone can find anything at any time. Complete navigability. Morville discusses the Internet, GIS, and other network technologies that are coming together to make unlimited findability possible. He explores how the melding of these innovations impacts society, since Web access is now a standard requirement for successful people and businesses. But before he does that, Morville looks back at the history of wayfinding and human evolution, suggesting that our fear of being lost has driven us to create maps, charts, and now, the mobile Internet.

    Rez. in: nfd - Information Wissenschaft und Praxis 57(2006) H.3, S.177-178 (D. Lewandowski): "Wohl unbestritten ist, dass die Suche in Informationsbeständen eine immer größere Bedeutung erhält. Wir suchen nicht nur noch explizit, indem wir ein Informationssystem anwählen und dort eine Suche absetzen, sondern verwenden Suchfunktionen innerhalb von Programmen, auf Websites, innerhalb des Betriebssystems unseres Computers oder sogar ziemlich unbewusst, indem wir Informationen maßgeschneidert aufgrund einer einmal hinterlegten Suche oder eines automatisch erstellten Suchprofils erhalten. Man kann also in der Tat davon sprechen, dass wir von der Suche umgeben werden. Das ist mit dem Konzept der "Ambient Findability" gemeint. Angelehnt ist diese Bezeichnung an den Begriff der "Ambient Music" (in den 70er Jahren durch Brian Eno geprägt), die den Hörer umgibt und von ihm oft gar nicht aktiv wahrgenommen wird. Um eine Vorstellung von dieser Musik zu bekommen, eignet sich vielleicht am besten der Titel einer Platte eben von Brian Eno: "Music for Airports". Peter Morville, bekannt als Co-Autor des empfehlenswerten Buchs "Information Architecture for the World Wide Web"', hat sich nun mit der Veränderung der Suche auseinandergesetzt. Sein Buch bedient sich in ganz unterschiedlichen Disziplinen, um die Prozesse des Suchens, Stöberns und Findens aufzuzeigen. So finden sich Betrachtungen über die Orientierung des Menschen in unbekannten Umgebungen, über die Interaktion mit Informationssystemen, über das soziale Verhalten der Web-Nutzer (Stichworte: Content-Tagging, Folksonomies, Social Networking) und über technische Veränderungen durch die Verfügbarkeit von Informationssystemen in allen Lebenskontexten, vor allem auch über mobile Endgeräte. Das Buch ist in sieben Kapitel gegliedert. Das erste, "Lost and Found" betitelt, bietet auf wenigen Seiten die Definitionen der zentralen Begriffe ambient und findability, erläutert kurz das Konzept der Information Literacy und zeigt, dass die bessere Auffindbarkeit von Informationen nicht nur ein schöner Zusatznutzen ist, sondern sich für Unternehmen deutlich auszahlt.
    Das zweite Kapitel ("A Brief History of Wayfinding") beschreibt, wie Menschen sich in Umgebungen zurechtfinden. Dies ist insofern interessant, als hier nicht erst bei Informationssystemen oder dem WWW begonnen wird, sondern allgemeine Erkenntnisse beispielsweise über die Orientierung in natürlichen Umgebungen präsentiert werden. Viele typische Verhaltensweisen der Nutzer von Informationssystemen können so erklärt werden. So interessant dieses Thema allerdings ist, wirkt das Kapitel leider doch nur wie eine Zusammenstellung von Informationen aus zweiter Hand. Offensichtlich ist, dass Morville nicht selbst an diesen Themen geforscht hat, sondern die Ergebnisse (wenn auch auf ansprechende Weise) zusammengeschrieben hat. Dieser Eindruck bestätigt sich auch in weiteren Kapiteln: Ein flüssig geschriebener Text, der es jedoch an einigen Stellen an Substanz fehlen lässt. Kapitel drei, "Information Interaction" beginnt mit einem Rückgriff auf Calvin Mooers zentrale Aussage aus dem Jahre 1959: "An information retrieval system will tend not to be used whenever it is more painful and troublesome for a customer to have information than for him not to have it." In der Tat sollte man sich dies bei der Erstellung von Informationssystemen immer vergegenwärtigen; die Reihe der Systeme, die gerade an dieser Hürde gescheitert sind, ist lang. Das weitere Kapitel führt in einige zentrale Konzepte der Informationswissenschaft (Definition des Begriffs Information, Erläuterung des Information Retrieval, Wissensrepräsentation, Information Seeking Behaviour) ein, allerdings ohne jeden Anspruch auf Vollständigkeit. Es wirkt vielmehr so, dass der Autor sich die gerade für sein Anliegen passenden Konzepte auswählt und konkurrierende Ansätze beiseite lässt. Nur ein Beispiel: Im Abschnitt "Information Interaction" wird relativ ausführlich das Konzept des Berrypicking nach Marcia J. Bates präsentiert, allerdings wird es geradezu als exklusiv verkauft, was es natürlich bei weitem nicht ist. Natürlich kann es nicht Aufgabe dieses Buchs sein, einen vollständigen Überblick über alle Theorien des menschlichen Suchverhaltens zu geben (dies ist an anderer Stelle vorbildlich geleistet worden'), aber doch wenigstens der Hinweis auf einige zentrale Ansätze wäre angebracht gewesen. Spätestens in diesem Kapitel wird klar, dass das Buch sich definitiv nicht an Informationswissenschaftler wendet, die auf der einen Seite mit den grundlegenden Themen vertraut sein dürften, andererseits ein wenig mehr Tiefgang erwarten würden. Also stellt sich die Frage - und diese ist zentral für die Bewertung des gesamten Werks.

    Abstract
    E-sciences are data-intensive sciences that make a large use of the Web to share, collect, and process data. In this context, primary scientific data is becoming a new challenging issue as data must be extensively described (1) to account for empiric conditions and results that allow interpretation and/or analyses and (2) to be understandable by computers used for data storage and information retrieval. With this respect, metadata is a focal point whatever it is considered from the point of view of the user to visualize and exploit data as well as this of the search tools to find and retrieve information. Numerous disciplines are concerned with the issues of describing complex observations and addressing pertinent knowledge. In this paper, similarities and differences in data description and exploration strategies among disciplines in e-sciences are examined.

    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.
