- Abstract
- Dirk Lewandowski (HAW Hamburg) hatte mit dem Titel seines Referates auf der Veranstaltung zur "Zukunft der Informationswissenschaft - Hat die Informationswissenschaft eine Zukunft?" an der UB der TU Berlin Brisanz angekündigt. Sein Titel lautete: "Warum die Frage nach der Zukunft der Informationswissenschaft falsch gestellt ist". Dabei war die Veranstaltung auf der Basis des Buches "Zukunft der Informationswissenschaft - Hat die Informationswissenschaft eine Zukunft?" entwickelt worden. Wie sich zeigte, war Lewandowski der erste, der sich öffentlich mit den in dem Buch erhobenen Kritiken zum Stand der Informationswissenschaft umfassend auseinandergesetzt hatte und damit die dort geführte informationswissenschaftliche Debatte fortführte. Damit kam er den impliziten Wünschen der Autoren entgegen, die sich in dem Buch kritisch zum Stand der Informationswissenschaft geäußert hatten. Der Referent erklärte, er habe sich nach der Lektüre des Buches gefragt (oder nach den ersten 150 Seiten des Buches, auf denen Grundfragen der Informationswissenschaft erörtert werden - anschließend geht es mehr um eine Leistungsschau der Disziplin in Forschung und Lehre): "Von welcher Informationswissenschaft ist hier eigentlich die Rede?" und sich darauf die Antwort gegeben: "Das ist nicht die Informationswissenschaft, wie ich sie kenne." Die Grundhaltung der Autoren im Buch seien Zweifel an der Zukunft der Informationswissenschaft wenn nicht an der Zukunftsfähigkeit des Faches gewesen. Lewandowski widersprach diesen Kritikern mit den Worten, dass er keine Zweifel an der Zukunft der Informationswissenschaft habe. Wohl habe die Informationswissenschaft ein strukturelles, jedoch kein inhaltliches Problem. So habe Frauke Schade überzeugend nachgewiesen, dass sich die Informationswissenschaft mit allen Fragen der Digitalisierung, die die Politik in ihren Positionspapieren vom Wissenschaftsrat bis zum Rat für Informationsinfrastrukturen stelle, befasse.
