Selection of Selection of IRsIRs

OpenDOAR: an authoritative directory of academic open access repositories. There are 52 IRs . http://www.opendoar.org/

ROAR: 73 institutional repositories in India are listed under Registry of Open Access Repository. http://roar.eprints.org

Normalization of Data

Based on each indicator, all the selected IRs are arranged in descending order of magnitude and assigned a rank for them.

Calculation of Rank Calculation of Rank IndexIndex

Index Value may be calculated as:

20%.S + 40%.V + 15%.R + 15%.Sc + 5%.Ri + 5%.D

Where, S= Size, V= Visibility, Sc= Google Scholar, Ri= Rich Files & D= Duration

ConclusionConclusionTo maximize the visibility of

institution’s research outputs.

The authors’ visibility increases if their research outputs are available through open access institutional repositories.

Institutional visibility increases resulting into an increase in world rank of the institutes.

IR may be at global level, institutional level and departmental level.
