    Abstract
    Google Scholar's coverage of the engineering literature is analyzed by comparing its contents with those of Compendex, the premier engineering database. Records retrieved from Compendex were searched in Google Scholar, and a decade by decade comparison was done from the 1950s through 2007. The results show that the percentage of records appearing in Google Scholar increased over time, approaching a 90 percent matching rate for materials published after 1990.

    Abstract
    Ohne das Internet ist heute das Wissen der Welt kaum mehr vorstellbar - und ohne Suchmaschinen wäre es nicht auffindbar. Freilich steht nicht alles Wissen im Word Wide Web. Und erst recht nicht ist es dort zu finden, nicht einmal von dieser) technischen Wunderwerken, den Suchmaschinen, die uns dabei helfen. In den sechziger Jahren entstand Hypertext als eine einheitliche Darstellung und Verknüpfung von elektronischen Dokumenten. Im Jahr 1980 empfahl Tim Berners-Lee dem Genfer Kernforschungszentrum Cern einheitliche Verweise zwischen Dokumenten, sogenannte Links. Zu Weihnachten 1990 schrieb er dort den ersten Browser und erfindet damit das World Wide Web. Am 15. Dezember 1995 ging Altavista in Palo Alto ans Netz. Als wir hier einige Monate später über diese Suchmaschine berichteten, schätzten wir damals 30 Millionen Seiten im Interne. Inzwischen mag es da 300 Milliarden Dateien geben, wie viele, weiß keiner, nicht einmal die größte Suchmaschine. Die Technik der Suchmaschinen ist gleich geblieben. Sie suchen die Inhalte vorher, vor der Abfrage, mit Software, den "Krabblern", einer Erfindung des Franzosen Louis Monier. Die machen eine Liste aller vorkommenden Wörter und krabbeln dann, Link um Link, zu weiteren Seiten, von Datei zu Datei, von Domane zu Domäne, von Kontinent zu Kontinent. Wie genau die invertierten Dateien aussehen, die sie erzeugen, wie groß sie sind, wie dort Worthäufigkeit oder Stellung des Treffers auf der durchforschten Seite gespeichert ist - wichtig beim Sortieren der Ergebnisse -, wie daraus später geschlossene Wortgruppen herausgeholt werden, bleibt ein Betriebsgeheimnis. Einen kleinen Einblick gab uns Guido Adam, Technikchef der deutschen Suchmaschine Infoseek. In dieser Auskunftei mit 35 festen und noch einmal so vielen freien Mitarbeitern sind neun für den Katalog tätig. Die Rechner stehen in Darmstadt. In 19-Zoll-Gestellen laufen hinter Plexiglas sechs Krabbler-PCs mit 3 bis 8 Gigabyte (GB) Ram-Speicher und je hundert Krabbelprogrammen. Sie sind mit 640 Megabit je Sekunde ans Internet angeschlossen. Ihr Ziel: Wenigstens einmal mönatlich 30 Millionen deutsche Dateien besuchen. Erkennen sie häufig wechselnde Inhalte, kommen sie öfter vorbei; für ganz Aktuelles wie Zeitungsberichte gibt es Sondersucher, die notfalls stündlich nachlesen. Zwei weitere Maschinen bauen immerfort neue Indizes und legen die Ergebnisse in einem Speicher-Server mit brutto 5 Terabyte (5 mal 10**12 Byte) ab. Der Index - jeweils rund 350 GB - wird fünffach gehalten, damit Anfragen blitzschnell - in etwa einer Sekunde - von drei weiteren Maschinen beantwortet werden können. Index-"Instanz" Nummer vier ist Reserve und die fünfte im Aufbau.
