Initially research activities in LIS were at low pace. As a result, only 25 PhDs were awarded during 1950-1982 (0.75 PhDs per annum) but during 1983-1992, research activities got sudden momentum showing continuously rising trend with the award of 196 PhDs (19.6 PhDs per annum). This rise was still higher during 1993- 2002 when 485 PhDs were awarded (48.5 per annum) and highest in 2003-2012 with 1048 PhDs (104.8 per annum) just in three years. Pradesh, Tamil Nadu, and Andhra Pradesh together contribute to 53.13 % of total output. This picture is emerging because the number of universities is more in these states.
