Public Knowledge Project announced on June 11 that Athabasca University Press is partnering with PKP's effort to develop Open Monograph Press, an electronic publishing platform for monographs. Athabasca UP will contribute its experience with scholarly publishing as well as developer time.
PKP is also seeking additional partners to contribute developer time, feedback, funding, or testing. Interested collaborators should join the new OMP section of the PKP Support Forum.
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.
