The Ranking of Repositories is published since 2008 and two editions are available usually at the end of January and July. The January 2011 edition is available from here:
http://repositories.webometrics.info/ This edition consists of more than 1,200 repositories, ranked according to a composite index that combines activity indicators (size, rich files and Scholar) and impact (link visibility). The repositories should have their own web domain or subdomain and include at least peer-reviewed papers to be considered (services that contain only archives, databanks or learning objects are not ranked). A separate ranking (Top Portals) is devoted to national services, international platforms and portals of journals, but it is still in beta version. The list is headed by the subject repositories: SSRN is the first, Arxiv the second and close to them CiteSeerX and RepEC. As usual we thank any comment, suggestion or criticism.
