I just mailed the December 2009 issue of the SPARC Open Access Newsletter. This issue takes a close look at the OA implications of the amended version of the Google book settlement. The roundup section briefly notes 150 OA developments from November.
The open access movement:
Putting peer-reviewed scientific and scholarly literature
on the internet. Making it available free of charge and
free of most copyright and licensing restrictions.
Removing the barriers to serious research.
I recommend the OA tracking project (OATP) as the best way to stay on top of new OA developments. You can read the OATP feed on a blog-like web page or subscribe to it by RSS, email, or Twitter. You can also help build the feed by tagging new developments you encounter.
