Welcome to the 13th edition of the Ranking Web of Repositories, that it is published since 2008. Two standards editions are available usually at the end of January and July.
The criteria for inclusion are very simple: 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).
Although there is a paper describing the Ranking, Aguillo, I.F., Ortega, J.L., Fernández, M., Utrilla, A.M. (2010). Indicators for a webometric Ranking of Open Access Repositories. Scientometrics, 82 (3): 477-486. (You can get the author's edition in Open Access), there are some important changes in the methodology. The indicators and weighting are described below::
Published figures are RANKS (lower is better), intended for showing individual performances, but they are not the values used in the calculations.
