    Abstract
    Das Information Retrieval steht in theoretischer und praktischer Hinsicht im Zentrum der Informationswissenschaft. Das Buch vereinigt beide Bereiche, indem es seinen praktischen Ausgang von realen Situationen der Online-Informationsvermittlung nimmt und zugleich einen wichtigen Beitrag zu einer Theorie der Frageformulierung in Information Retrieval an sich leistet. Mit 'realen Situationen' sind mitprotokollierte Online-Sitzungen bzw. CD-ROM Recherchen gemeint. Diese Recherchen wurden teils kooperativ, d.h. zusammen mit den Endbenutzern, oder nicht-kooperativ, d.h. alleine von professionellen Informationsvermittlern, durchgeführt und in der Arbeit ausgewertet. Die Studie ist damit der sog. verhaltensanalytischen Richtung des Information Retrieval zuzurechnen
