PHYSICS ABSTRACTING—USE AND USERS Available to Purchase

In May 1963 a survey was made of the sources of references to publications requested from the National Lending Library for Science and Technology. This survey, in conjunction with the one carried out by the Advisory Council on Scientific Policy on the information needs of physicists and chemists, throws some light on the needs of physicists. There is some evidence to suggest that physicists need a current title publication and improved indexes.
