    Footnote
    Für wen wurde dieses Buch eigentlich geschrieben? Der Verlag, sonst für eher praktisch orientierte Computerbücher bekannt, ordnet es auf dem Umschlag den Bereichen "Marketing" sowie "Technology & Society" zu. Für letztere Zielgruppe ist es aber sicher weniger geeignet, da auch der gesellschaftliche Hintergrund zu dünn ist. So bleibt der Bereich Marketing oder doch eher die Zielgruppe derjenigen, die ohne fachbezogenes Studium in den Bereich Informationssysteme bzw. Informationsarchitektur "hineingeschlittert" sind. Für diese mag auch das Kapitel über "Information Interaction" (bedingt) geeignet sein, bietet es doch zumindest einen gut lesbaren Einblick in einige zentrale Punkte. Das vierte Kapitel ("Intertwingled") beschreibt den Zugriff auf Informationen mittels verschiedener Erdgeräte in unterschiedlichen Kontexten. Es geht hier neben neuen Ansätzen des Wegefindens, um lokalisierbare Objekte und Kleidung, in die Informationstechnologie mit eingebaut ist. Dabei handelt es sich um einen guten (und vor allem beispielreichen) Überblick der aufkommenden Technologien. Kapitel s behandelt die Integration von Push- und PullAnsätzen, wobei die zentrale Aussage lautet, dass beide Ansätze immer mehr zusammenwachsen und die Entscheidung für den einen oder den anderen Ansatz vom Nutzer spontan gemäß seinen Informationsbedürfnissen getroffen wird. In diesem Kapitel wird auch das Thema Personalisierung abgehandelt und auf die bei der Personalisierung entstehenden Probleme eingegangen. Lange Zeit wurde Personalisierung schlicht als ein Verfahren gesehen, aus einmal erfassten Nutzerdaten Empfehlungen abzuleiten. Dass dies nicht problemlos möglich ist, erläutert Morville an einigen Punkten. Etwas bedauerlich ist hier, dass die Erläuterungen sehr knapp gehalten sind. Gerade zu diesem interessanten Thema hätte man gerne mehr Details erfahren.
    Im Kapitel über das "Sociosemantic Web" werden die groben Grundzüge der Klassifikationslehre erläutert, um dann ausführlich auf neuere Ansätze der Web-Erschließung wie Social Tagging und Folksonomies einzugehen. Auch dieses Kapitel gibt eher einen Überblick als den schon Kundigen vertiefende Informationen zu liefern. Das letzte Kapitel widmet sich schließlich der Art, wie Entscheidungen getroffen werden, der Network Culture, dem Information Overload, um schließlich zu den "Inspired Decisions" zu gelangen - Entscheidungen, die sowohl auf "sachlichen Informationen" (also den klassischen Zutaten der "informed decisions") als auch aus aus Netzwerken stammenden Informationen wie etwa Empfehlungen durch Freunde oder Community-Mitglieder irgendeiner Art gewonnen werden. Fasst man zusammen, so ist an Morvilles Text besonders bemerkenswert, dass nach einigen Jahren, in denen die Suche im Web als ein Problem der Suche in unstrukturierten Daten angesehen wurde, nun wieder verstärkt Erschließungsansätze, die auf klassische Erschließungsinstrumente zurückgreifen, propagiert werden. Zwar sollen sie nicht in ihrer ursprünglichen Form angewandt werden, da den Nutzern nicht zuzumuten ist, sich mit den entsprechenden Regeln auseinanderzusetzen, aber auch hinter der auf den ersten Blick zumindest chaotisch wirkenden Folksonomy ist das Prinzip der Klassifikation zu erkennen. Um die modernen Ansätze erfolgreich zu machen, bedarf es aber dringend Information Professionals, die das "beste aus beiden Welten" verbinden, um moderne, für den Nutzer optimale Informationssysteme zu schaffen. Für die Gesamtbewertung des Buchs gelten die bereits zu einzelnen Kapitels angeführten Kritikpunkte: In erster Linie bleibt das Buch zu sehr an der Oberfläche und wirkt irgendwie "zusammengeschrieben" anstatt als Ergebnis der tiefgreifenden Beschäftigung mit dem Thema. Als eine Einführung in aufkommende Technologien rund um die Suche ist es aber durchaus geeignet - gut lesbar ist der Text auf jeden Fall.
