Abstract
Untersucht man die Verteilung der Autorenhäufigkeit in wissenschaftlichen Zeitschriften, hier kurz Journals Author Distri-bution (JAD) genannt indem man über mehrere Jahre die Verteilung der Häufigkeit prüft wie viele Autoren einmal, zweimal, dreimal etc. in dieser Zeitschrift erschienen, so zeigen sich charakteristische Verteilungen, die den allgemeinen Potenzgesetzen (power laws) folgen. Diese Verteilungen können als Typologie der speziellen Journale verwendet werden. Wie der Impact Factor, der Immediacy Factor oder die Halbwertzeit ist die JAD zur Kategorisierung einer Zeitschrift nützlich. Auffallend ist dabei, dass zwei Parameter, der Beginn der hyperbolischen Funktion und die Potenz in einem eher konstanten Verhältnis stehen. Den Konsequenzen dieser Beobachtung wird hier nachgegangen.
