Abstract

This paper presents a bibliometric analysis of the Growth rate and core journals in the field of Lung Cancer covered in MEDLINE data which are covered in the Pubmed during the study period i.e. 2010 to 2015. It was found that 42.93% records were Journal Article. It is noticed that 64180 of the records on ‘Lung Cancer’ are covered in the MEDLINE database for a period of six years. It is found that the maximum number of records (14692) was published during the year 2015, followed by 14626 in 2014 and 13167 in 2013. RGR has been decreasing from 2011 (2.73) to 2015 (0.26). On the other hand, the Doubling Time (Dt) has shown an increasing trend. It is also found that 53 core journals grouped in zone 1 published 9211 articles accounting for one third of the total output. Similarly the second zone comprises of 291 journals and 2759 journals grouped in third zone. The research productivity of Lung Cancer confirms the implication of Bradford’s Law of Scattering.
