Abstract

Das Informationsangebot in der Chemie ist, im Unterschied etwa zur Biologie, fast völlig von kommerziellen Anbietern dominiert, deren elektronische Produkte vor allem einen zahlungskräftigen Industriemarkt bedienen. Das ist eine für Hochschulen problematische Situation, trotz zahl reicher "academic programs" für solche Datenbanken. Die Produzenten haben in den letzten Jah ren u.a. durch Erweiterung der inhaltlichen Erfassung, Erwerb weiterer Datenbanken und Optimierung ihrer Benutzeroberflächen für Endnutzer versucht, ihre Marktanteile zu vergrössern. Vor diesem Hintergrund stellt sich die Frage, ob nicht eine oder zwei dieser kostspieligen, umfangreichen Quellen für Endnutzer die wesentlichen Bedürfnisse im Bereich Sekundär/Tertiärliteratur abdecken kann. Aufgrund unserer langjährigen Rechercheerfahrung und von Datenbankvergleichen müssen wir diese Frage leider verneinen.
