2010 Ranking Web of Repositories

The second edition of 2010 Ranking Web of Repositories has been published:
http://repositories.webometrics.info/

Close to 1000 repositories have been analyzed this year and the top 800 are ranked here according to their web presence and visibility. The aim of this ranking is to support Open Access initiatives and therefore the free access to scientific publications in an electronic form and to other academic material. The web indicators are used here to measure the global visibility and impact of the scientific repositories. Two lists are available - top 800 and top 800 institutional.

I've done a bit of trawling and number crunching on the institutional list extracting both a ranked list for UK only institutional repositories, and a subset of those Welsh repositories that appear in the list. Of the top 800 institutional repositories globally the UK has 82 entries and Wales has five entries from those. Details:
