PS: One important resource missing from the summary is PhilPapers, which entered its public beta on January 28, 2009. A project of David Chalmers and David Bourget, PhilPapers is an OA repository open to papers on all topics in the field.

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.
