Scientometrics is concerned with the quantitative features and characteristics of science and scientific research. Emphasis is placed on investigations in which the development and mechanism of science are studied by statistical mathematical methods.

The journal publishes original studies, short communications, preliminary reports, review. CONDENSATES (Chemical Abstracts) are all readily accessible and provide improved literature searching of published in- formation.

Smaller files, such as scientists’ personal literature collections, have also been successfully computerized.

Chemical Abstracts offers the best example of thoroughness in this respect, but Nuclear Science Abstracts is very realistic in its coverage of both published and unpublished material.

Chemical Abstracts issues every five years a list of journals and other serial material covered, with their locations in libraries. Photostat copies of articles.
