Chopra previously served as Secretary of Technology for the state of Virginia. In that role, he supported Virginia's "flexbook" program to develop open textbooks. Chopra was also a member of the Obama transition's Technology, Innovation and Government Reform working group, which discussed topics such as OA to public sector information and open data.
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.
