I just mailed the March issue of the SPARC Open Access Newsletter. This issue takes a close look at the re-introduction of the Fair Copyright in Research Works Act (a.k.a. the Conyers bill, HR 801), which would repeal the OA policy at the NIH and block similar policies at all other federal agencies. The round-up section briefly notes 129 OA developments from February.
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.
