The Federal Government was the second 

 largest producer of published research reports in 

 1973, with an average of 11 percent of the total 

 reports from the 13 fields. The proportion of the 

 total research publications produced by this 

 sector declined, however, in all fields between 

 1960 and 1973, with the largest decreases 

 occurring in oceanography, chemistry, and 

 physics. In 1973, this sector accounted for a 

 significant share of total research publications in 

 the fields of astronomy (29 percent), ocean- 

 ography (21 percent), geology (18 percent), and 

 astronomy (16 percent). 



Private industry's share of research 

 publications in 1973 averaged 10 percent among 



all fields as a whole, with the largest fractions in 

 the fields of engineering (44 percent), chemistry 

 (18 percent), and physics (16 percent). The 

 proportion of total publications for which this 

 sector was responsible declined in all fields — 

 other than the atmospheric sciences and 

 oceanography — between 1960 and 1973. The 

 largest declines were recorded in engineering, 

 physics, and chemistry. 



Nonprofit organizations produced the 

 remaining 5 percent of total publications in 1973, 

 down from some 10 percent in 1963. 



It is clear from these indicators that academic 

 institutions are predominant in the production
