SURF has released an English synopsis of The Dutch Research Repositories Monitor 2011.
Here's an excerpt:
This study measures the effects of the two networks of repositories [DARE programme and SURFshare programme], charts the current situation, and explores possible scenarios for the future. It is in part a follow-up to the study Dutch Academic Repositories SURFshare Baseline Survey [Nederlandse Academische Repositories, SURFshare Nulmeting] of March 2010. That study was a baseline survey of the Dutch universities’ repositories carried out at the end of 2008 and with additional research in the first half of 2009. Important statistics in the study concern the 2007 calendar year. In other words, despite being published in 2010, the results were in fact a number of years old, namely from the start of the SURFshare programme.
