Title
¬Die Halbwertszeit in der naturwissenschaftlichen Literatur

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
