The ROARMAP Registry of Green Open Access Mandates has been upgraded:

With University of North Texas's mandate (approved by UNT Faculty
Senate March 9 2011) there are now 193 Green OA Mandates by
institutions and funders worldwide (plus 75 thesis mandates).

This would be an opportune time for you to register your mandate, if
it is not registered already.
