- Eugine Garfield

Started in1991The first of its kind in the world.Brainchild of Paul Ginsparg, a physicist.

Covered fieldsPhysics, mathematics, non-linear science, computer science, quantitative biology and statistics

Operated and funded byCornell 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 studyIt 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.

CONCLUDING REMARKS

.The study reveal that e-print archives have become the first choice of many researchers like journal articles for their R&D activities.

E-Print 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.

Thanks one and all
