Abstract

Die wachsende Anzahl der in der Literatur behandelten Themen und der steigende Anteil der Arbeiten zu sogenannten Mikrosachverhalten haben die Schwierigkeiten der Sacherschließung immer größer werden lassen. Um dieser Schwierigkeiten Herr werden zu können brauchen wir vor allem: 1. für jeden Begriff eine Kette von leicht erkennbaren Gesichtspunkten und Merkmalen, nach denen er bis zu beliebig engen Unterbegriffen hin sukzessive zerlegt werden kann, 2. Methoden, welche es erlauben, Begriffsrelationen, etwa die teilweise Überschneidung von Begriffen, in einfacher Weise darzustellen und 3. für jeden Begriff eine eindeutige, möglichst ohne Modifikation für das Ordnen nach dem Alphabet verwendbare Benennung.
