The presentations from the conference, Designing Cyberinfrastructure for Collaboration and Innovation (Washington D.C., January 29-30, 2007), are now online. The conference was sponsored by sponsored by the US National Science Foundation, the University of Michigan, the Council on Competitiveness, and Science Commons.
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.
