Ranking of repositories


Since 2014 the Open Access Repository Ranking (OARR) gives an overview over the quality of the German institutional repository landscape.


Cybermetrics Lab, a research group which belongs to the Consejo Superior de Investigaciones Científicas (CSIC), one of the largest public research bodies in Spain, regularly releases a ranking of institutional and disciplinary repositories. The purpose of the ranking is to support the open access movement and thus free access to academic material. The ranking, which is based on quantitative Web indicators such as hit rates and backlinks, is supposed to be understood as an reflection of the visibility and impact of scientific Web repositories.
