Abstract

This paper presents a scientometric analysis of the growth of literature output in the field of Genetic Engineering using MEDLINE data which are covered in the Pubmed. The literature covered in the database for the period 1989-2013 was considered. It covered the maximum of 191089 records during the study period from 1989 to 2013. It is found that the annual growth rate of literature in a particular field of knowledge is uniform and measure the rate of growth from year after year, the application of RGR and Dt are quite appropriate. The RGR has shown a decreasing trend and Doubling Time shown an increasing trend. It is also found that the annual growth rate of literature of journal articles in a particular field the RGR has shown a decreasing trend and Doubling Time shown an increasing trend. Genetic Engineering research indicates a different picture when the RGR and Dt were calculated by year-wise both in terms of number of papers and number of pages. It is found that the year wise calculation of RGR and Dt for Indian output has shown fluctuation trends throughout the study period.
