    Abstract
    Aus der Benutzung der Universitätsbibliothek Ulm wurde eine Halbwertszeit-Funktion in der naturwissenschaftlichen Literatur von t1/2=5 Jahren bestimmt. Eine interessante Abweichung von dieser Halbwertszeit-Funktion ist bei der Bestellung der neuesten Zeitschriften zu beobachten. Der Grund hierfür liegt vermutlich darin, daß Wissenschaftler das Vierfache an neuester Literatur lesen müssen, um wissenschaftliche Trends zu überschauen. Eine weitere Abweichung ist in der ältesten Literatur festzustellen, bei den sog. 'citation classics'. Übereinstimmung zeigt sich im Zitier- und Kopierverhalten bei Zeitschriftenliteratur, die älter als 2 Jahre ist. Etwa 27% der an die UB Ulm gerichteten Literaturanforderungen betreffen Zeitschriftenaufsätze mit einem Alter von über 10 Jahren, da diese Bestände für die Benutzer nur schwer zugänglich sind. Dies zeigt die große Bedeutung einer Freihand-Bibliothek

    Abstract
    Thesauri have been used in the library and information science field to provide a standard descriptor language for indexers or searchers to use in an informations storage and retrieval system. One difficulty has been the maintenance and updating of thesauri since terms used to describe concepts change over time and vary between users. This study investigates a mechanism by which thesauri can be updated and maintained using citation, co-citation analysis and citation context analysis.

    Abstract
    Scientific documents are more or less important in relation to give subjects and this importance can be measured. An empirical investigation into philosophical information was carried out using a weighting algorithm developed by N. Henrichs which results in a distribution by weighting of documents on an average philosophical subject. With the aid of statistical methods a threshold value can be obtained that separates the important and unimportant documents on a subject. The knowledge of theis threshold value is important for various practical and theoretic questions: providing new possibilities for research strategy in information retrieval; evaluation of the 'titleworthiness' of subjects by comparison of document titles and themes for which the document at hand is important; and making available data on thematic trends for scientific results
