I just mailed the October issue of the SPARC Open Access Newsletter. This issue takes a close look at the bill to overturn the NIH public access policy, the Fair Copyright in Research Works Act (H.R. 6845), and the publishing lobby's arguments in support of it. The round-up section briefly notes 149 OA developments from September.
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.
