Distribution of physics literature

  • R. Todorov


Percentage distributions of physics papers in 36 countries over ten subfields are compared. Factor and cluster analyses are applied to data from 1978Physics Abstracts. Countries load highly on seven factors. Their meaning is estimated by factor scores. Clusters of countries with similar publishing patterns are presented in a tree diagram.
