Isidro, Thank you for your Ranking Web of World Repositories and for informing us about the best quality repositories!
Being French, I am delighted to see HAL so well ranked and I take this opportunity to congratulate Franck Laloe for having set up such a good national repository as well as the CCSD team for continuing to maintain and improve it. Nevertheless, there is a problem in your ranking that I have already had occasion to point out to you in private messages. May I remind you that: Correction for the top 800 ranking: The ranking should either index HyperHAL alone, or index both HAL/INRIA and HAL/SHS, but not all three repositories at the same time: HyperHAL includes both HAL/INRIA and HAL/SHS . Correction for the ranking of institutional repositories: Not only does HyperHAL (#1) include both HAL/INRIA (#3) and HAL/SHS (#5), as noted above, but HyperHAL is a multidisciplinary repository, intended to collect all French research output, across all institutions. Hence it should not be classified and ranked against individual institutional repositories but as a national, central repository. Indeed, even HAL/SHS is multi-institutional in the usual sense of the word: single universities or research institutions. The classification is perhaps being misled by the polysemous use of the word "institution." Not to seem to be biassed against my homeland, I would also point out that, among the top 10 of the top 800 "institutional repositories," CERN (#2) is to a certain extent hosting multi-institutional output too, and is hence not strictly comparable to true single-institution repositories. In addition, "California Institute of Technology Online Archive of California" (#9) is misnamed -- it is the Online Archive of California http://www.oac.cdlib.org/ (CDLIB, not CalTech) and as such it too is multi-institutional. And Digital Library and Archives Virginia Tech University (#4) may also be anomalous, as it includes the archives of electronic journals with multi-institutional content. Most of the multi-institutional anomalies in the "Top 800 Institutional" seem to be among the top 10 -- as one would expect if multiple institutional content is inflating the apparent size of a repository. Beyond the top 10 or so, the repositories look to be mostly true institutional ones. I hope that this will help in improving the next release of your increasingly useful ranking!

The ranking is available from the following URL: http://repositories.webometrics.info/ The main novelty is the substantial increase in the number of repositories analyzed (close to 1000). The Top 800 are ranked according to their web presence and visibility. As usual thematic repositories (CiteSeer, RePEc, Arxiv) leads the Ranking, but the French research institutes (CNRS, INRIA, SHS) using HAL are very close. Two issues have changed from previous editions from a methodologicall point of view:, the use of Bing's engine data has been discarded due to irregularities in the figures obtained and MS Excel files has been excluded again. At the end of July the new edition of the Rankings of universities, research centers and hospitals will be published. Comments, suggestions and additional information are greatly appreciated. -- =========================== Isidro F. Aguillo, HonPhD Cybermetrics Lab (3C1) IPP-CCHS-CSIC Albasanz, 26-28 28037 Madrid.
