Abstract
Considers the development in subject heading systems in Europe and America in recent years. Presents these developments in terms of the indexing languages used, the methods of subject analysis used, and the instruments comprised by the different systems (e.g. the rules governing the control of vocabulary and the construction of strings). Discusses the principles underlying the systems
