The CLEO blog has a list of 22 journals recently accepted to the Revues.org platform. Another 16 journals are listed as "coming soon" on revues.org. Most, if not all, will offer either immediate or delayed OA. Some journals may have previously been available online, while others were not.

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.
