    Abstract
    In diesem Papier soll die Rolle des FIZ Karlsruhe auf dem Gebiet des elektronischen Publizierens dartgestellt werden. Die Produktion von wissenschaftlich-technischen Datenbanken wird weitergeführt und der Online-Service STN International soll weiter ausgebaut werden. In Ergänzung hierzu werden Kooperationen mit Bibliotheken und Verlagen vereinbart, um eine umfassende Volltextversorgung für Literatur und Patente sicherzustellen. Zusätzlich wird ein Konzept für einen Electronic Information and Publishing Service erarbeitet, das folgende Komponenten umfaßt: (i) eine Volltextarchivierung der Originalmanuskripte in unveränderlicher Form, (ii) ein Online-Angebot der Volltexte und (iii) einen Editorial-Service zur Unterstützung der Verlage beim elektronischen Publizieren

    Abstract
    Large chemical structure databases available through online hosts need special software for substructure searching. Describes a study which compares the systems of STN International (messenger) and DIALOG (S4) with respect to: architecture, functionality and performance. The 2 systems are very similar with respect to their search capabilities and many features are almost identical. The number of hits differ slightly due to the different treatment of some special chemical effects. The average search times are faster for the S4 system than for the Messenger system but the Messenger system can be adopted to large files by using the search engine technology. S4 is very well suited to the Beilstein and Gmelin databases, while Messenger provides more general capabilities
