    Rez. in: iwp 62(2011) H.8, S.398-400 (A.R. Brellochs): " ... An der faktisch gegebenen Positionierung als Textbuch für Information Retrieval, einigen Themenfeldern der Informationsvermittlung und des Bibliothekswesens ist zwar grundsätzlich nichts auszusetzen. Leider führt aber die Vielzahl der behandelten Themen dazu, dass trotz des Umfangs von gut 500 Seiten manche für das IR wichtige Themen nur sehr knapp abgehandelt wurden. Diese thematische Überbreite macht den Band leider als generelle Einführung für Leser ohne fachlichen Hintergrund in Informations- oder Bibliothekswissenschaft ungeeignet, denn für diese ist ein großer Teil des Buches nicht ausreichend verständlich.
