Subject: [Web4lib] Ranking Web of Repositories and pdf suffixes

Thanks for your suggestions. We have just added them to the new edition 
of the Ranking Web of Repositories that has been published today.

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 her:

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. PMC and others 
repositories not using suffixes are being penalized both by the search 
engines and the Ranking.

As usual we thank any comment, suggestion or criticism.

Best,
