    Abstract
    Innovative Ideen setzen sich in den meisten Fällen schwer durch. Die elektronische Revolution erfordert neues Management und neue Organisation auf dem Informationsmarkt. Ein Instrument, das zunehmend an Bedeutung gewann, ist die ISBN Nummer, die jedem Buch seine Individualsignatur gibt und daher zur Globalisierung des Marktes beitrug. Hartmut Walravens hat die Entwicklung der ISBN maßgeblich beeinflusst, die durch die umfassende Bibliographie und einen Überblick dokumentiert wird.
