- Abstract
- An 2 biowissenschaftlichen Einrichtungen der Grundlagenforschung, dem Max-Delbrück-Centrum für Molekulare Medizin, Berlin-Buch und dem Leibniz-Institut für Neurobiologie, Magdeburg, wurden 1997 bzw. 1998 Nutzerbefragungen durchgeführt. Obwohl die untersuchten Gruppen beträchtliche Altersunterschiede aufwiesen, ergeben sich einheitliche Trends: für etwa 2/3 der Wissenschaftler ist gegenwärtig die Nutzung von Printmedien und elektronischen Informationsofferten gleichwertig, während etwa 15% der Befragten letzteren den Vorzug geben. Bei der Datenbanknutzung ist festzustellen, daß MEDLINE die überragende Position sowohl bei der CD-ROM als auch Online im Internet einnimmt
