Dear Dr. Kalyane,

Thank you for sending your interesting study. Perhaps we could
meet to discuss it further when I am in Mumbai in a few weeks
time (sept 5):

For now I would only point out that the physics arxiv contains both
preprints (i.e. pre-refereeing) and postprints (refereed) and that
preprints of course get cited earlier, because they become accessible
earlier. And both preprints and postprints get cited more, because they
are Open Access (and also because physicists tend to use arxiv as their
preferred means of access, as it contains so much in certain areas such
as HEP and astro).

It is interesting that the eprints are cited by high-impact journals
(but they also tend to have been self-archived by high-impact authors!).

You may be interested to see this recent article:
