Abstract
Vor 20 Jahren, genau gesagt am 26. Juli 1996, erblickte die Literatursuchmaschine "KVK" das Licht der Internet-Welt. Seit damals wurden mehrere Milliarden Suchanfragen von Karlsruhe aus an andere Web-Kataloge von Bibliotheken und Verbünden geschickt, Trefferlisten ausgewertet und den Nutzern in einheitlicher Form präsentiert. Dieser Beitrag erklärt, warum der KVK entwickelt wurde und warum es diesen "Internet-Dino" auch heute noch gibt und beschreibt den aktuellen Stand.
