From the February SPARC Open Access Newsletter, by Peter Suber

Every research funding agency should have an OA policy, many already do, and most are probably thinking about it.  Here's a guide to the major decisions which come up in framing a new policy, reviewing an older one, or thinking about policies elsewhere.  Peter Suber starts with the choice-points facing funding agencies (1-12), and then look briefly at the choice-points which only arise for universities (13-18).  He offers a recommendation for each.
