Open E-Print Archives Anybody can upload Any
documents/articles to the web server and is
accessible to Any one in the world
What about the quality of the uploaded e-print
archives ?
3
One of the prevalent measures to assess the
quality
Number of citations
4
Two measures based on citations to assess the
quality of journals as per Thomson Scientific
(Formerly Institute for Scientific Information,
Philadelphia)
Impact Factor
Number of citations received in the calculating
year to the previous two years articles __________
______________________________________________ Nu
mber of articles published in the previous two
years
Immediacy Index
Number of citations received in the calculating
year to the articles published in the calculating
year _____________________________________________
___________ Number of articles published in the
calculating year

Facts about arXiv.org (http//arxiv.org)
Started in 1991 The first of its kind in the
world. Brainchild of Paul Ginsparg, a
physicist. Covered fields Physics, mathematics,
non-linear science, computer science,
quantitative biology and statistics Operated and
funded by Cornell University, a private
not-for-profit educational institution and is
also partially funded by the National Science
Foundation, USA Reason for taking for the
present study It is one of the highly using
e-print archive service for current research,
breaking scientific discoveries, and keeping up
with colleagues by researchers around the world.

The physics category of arXiv.org is again
categorised in to 12 sub-classes as follows
  1. Astrophysics (astro-ph)
  2. Condensed Matter (cond-mat)
  3. General Relativity and Quantum Cosmology (gr-qc)
  4. High Energy Physics - Experiment (hep-ex)
  5. High Energy Physics - Lattice (hep-lat)
  6. High Energy Phyics - Phenomenology (hep-ph)
  7. High Energy Physics - Theory (hep-th)
  8. Mathematical Physics (math-ph)
  9. Nuclear Experiment (nucl-ex)
  10. Nuclear Theory (nucl-th)
  11. General Physics (physics)
  12. Quantum Physics (quant-ph)

CONCLUDING REMARKS
The study reveal that e-print archives have
become the first choice of many researchers like
journal articles for their RD activities. E-Prin
t archives certainly compete with journals
articles in terms of usage. The impact may go up
if the study could have used other citation
trackers like Google Scholar, Citebase,
Citeseer, and the databases like Scopus etc.
.

CONCLUDING REMARKS (continued.)
As a library professional we can certainly rely
on e-print archives for the requirements of our
clients. The present trend of using open
institutional repositories is very
appreciable. Ultimately both researchers and
library professionals enjoy the free access of
information and knowledge.
