A forthcoming article examines licenses and access controls for digital resources. "Open access has potential to address the erosion of public reading rights," the authors state. "It is unclear at this point, however, how successful the open access movement will be".
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.
