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!

Best wishes
Hélène Bosc

Ranking Web of Repositories: July 2010 Edition

The second edition of 2010 Ranking Web of Repositories has been
published the same day OR2010 started here in Madrid. The ranking is
available from the following URL:


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.
