Duke Law is relaunching its IR, the Duke Law Scholarship Repository. The new IR uses Digital Commons as its platform; the previous IR, launched in 2005, was based on EPrints. In addition to the school's journals and faculty's publications, the IR "ultimately will include the text of lectures delivered at Duke Law, webcasts from scholarly presentations and conferences, publications of Duke Law's research centers, Duke Law student works, and more".
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.
