Miriam Drake, Open Access for Physics: Interview with Marc Brodsky, Searcher, July/August, 2006. Only this blurb is free online:
Miriam Drake interviews Marc Brodsky, the executive director of the American Institute of Physics (AIP), about what role open access will play in the disbursement of physics research on the Web.
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.
