Dr Jeetender Chugh in his blog JC says has a suggestion on how to increase Impact Factors for Indian Journals
"..Govt should make a rule, which should be applicable to all the universities and institutes across India, that we, the researchers of India should publish all the work in Indian Journals only. The journals may be peer-reviewed internationally. The journals may be available online free of cost, and free copies may be sent to major universities worldwide.."
Dr Chugh is emphasising on two things - Govt. directive on scholarly publishing and free availability of Indian scholarly publications. It has been proved number of times that unrestricted online availability of of scholarly articles results in better impact (Online or Invisible? by Steve Lawrence; NEC Research Institute). Thus if Indian research is published through open access journals, it would make better impact on further research world wide. However it appears impractical to force authors to publish only in Indian Journals. However Govt. could mandate that publications arising from public funded research be archived in some Open Access archives within a specific time after their publication. A policy similar to NIH Public Access could be explored for such a mandate.
The NIH Public Access Policy ensures that the public has access to the published results of NIH funded research. It requires scientists to submit journal final peer-reviewed manuscripts that arise from NIH funds to the digital archive PubMed Central (http://www.pubmedcentral.nih.gov/). The Policy requires that these articles be accessible to the public on PubMed Central to help advance science and improve human health.
