Summary

This study evaluates the scientific output of Iran over the past two decades. The information has been extracted by searching ISI in December 2003. Science production in Iran has been reviewed (1967-2003) and compared with 15 countries in the year 2000. During these years Iran's relative share in the scientific output in the world increased from 0.0003% in 1970 to 0.29% in 2003. Comparing the ratio of science output to GNP, Iran stands on thirteenth place among 16 countries in the year 2000. The present article discusses that Iran has had an increasing growth in presenting articles after the Iraq-Iran war, which marks the period of stability and development.
