PHYSICS ABSTRACTS AS A SOURCE OF ABSTRACTS IN ASTRONOMY

The frequency and consistency of selection by Physics Abstracts of astronomical articles from three major journals, Nature, Astrophysical Journal, and Icarus, have been investigated. This has involved an examination of the probability of selection of an article as a function of its subject matter. As a result, it is possible to specify which fields of astronomy are best covered by Physics Abstracts. The time‐lag between the appearance of these articles and the subsequent appearance of their abstracts has also been examined.
