Abstract

Die elektronische Fachinformation bestand bislang vorwiegend aus klassisichen datenbanken. Mittlerweile zeichnet sich hier jedoch ein Wandel ab, der vor allem durch CD-ROM-publizierende Fachverlage getragen wird. Neben das auf dem Online-Markt dominierende Modell der klassischen Datenbank treten neue Formen der elektronischen Textvermittlung. Dieser Beitrag versucht eine Typologie der textuellen Information. Erwägungen zur korrespondierenden Abfragesoftware speziell im CD-ROM-Bereich und ein Asublick auf die nähere Zukunft sollen den Anbietern elektronischer Fachinformation als Entscheidungshilfe dienen
