Abstract
The origin of information for 5 genetics journals was traced for the years 1975, 1978 and 1982. Maps of the interrelationships between cited journals indicate that the information for genetics journals originates with the biochemical journals and passes down to the genetics journals via the multidisciplinary science journals. The 5 genetics journals can be divided into 2 levels: Level 1 — those journals that never cite each other but cite level 2 journals; Level 2 — those journals that serve as a source of information for level 1 journals. The use of level 2 journals by level 1 journals declines from 1975 to 1982 because of a decline in citations by two of the level 1 journals.
