    Abstract
    Das bit als Maß für das Verhältnis von Information, informationstheoretischem Rauschen, a posteriori Redundanz, a priori Redundanz bzw. Wissen, so wie es sich zunächst in den Betrachtungen zur Entropie, aus der Thermodynamik heraus ergeben hat, ist ein weitaus fundamentaleres Maß, als es zunächst aus der Thermodynamik und dem Eta-Theorem Boltzmanns heraus zu erwarten war, weil es uns die Möglichkeit gibt, das Wissen von Lebewesen, und von Systemen mit Künstlicher Intelligenz zu messen und nicht mehr wie bisher nur vergleichend abzuschätzen. Es ist ein Maß für Ordnung bzw. Redundanz und hat nichts mit Energie zu tun. Im Sinne Galileis, das zu messen, was messbar ist, und messbar zu machen, was noch nicht messbar ist, wird die Messbarkeit von Wissen im 21. Jahrhundert, in dem die Wissenschaft der dominierende Faktor der menschlichen Gesellschaft ist, fundamentale Bedeutung erlangen. Das bit ist im Gegensatz zu den klassischen naturwissenschaftlichen Maßsystemen, wie Meter, Kilogramm, Sekunde oder Kelvin nicht mehr ein anthropozentrisches, also vom Menschen beliebig gewähltes Maß, es ist die Konsequenz grundlegender wissenschaftlicher Einsichten des letzten Jahrhunderts über die Bedeutung der Entropie.

    Abstract
    Zunächst lässt sich die erste Frage im Titel rasch beantworten: Es war eigentlich ein Jahrzehnte altes Desiderat1 im modernen Bibliothekswesen eine internationale Einheitsklassifikation zu haben. Denn es wäre sicher wünschenswert, wenn man in jede Bibliothek der Welt gehen könnte, und wüsste, dass Bücher, CD-ROMs oder Filme, beispielsweise über Kinderpsychologie, immer unter der Notation 155.4 zu finden sind. Wenn man dann mit dem gleichen Einstieg noch im Internet relevantes finden könnte erschiene das vielen Nutzern sicher hilfreich. Als nächster aber keinesfalls weniger wichtiger Aspekt, kann die DDC2 auch zur Erfassung von Verlagsproduktionen und damit im Digital Rights Management (DRM) verwendet werden. Auch die zweite Frage ist im Prinzip leicht beantwortbar. Wenn die Bibliotheken und ihre Leser das Angebot adäquat nutzen, können sie daraus etliche Vorteile ziehen.
