Abstract  

Beside the continuous growth of the number of references per biochemical article from 1962 to 1977, an equalization tendency can be observed in the R/A values of the five leading biochemical journals investigated. While from 1962 to 1969 the number of more recent references (0–5 year old) had a higher growth rate than that of the older ones (6+year old), from 1969 to 1977 the situation turned to the opposite. The number of very recent (0–1 year old) references reached a saturation near the end of the sixties.
