UK PubMed Central launched a blog on March 2. Already it's posted several developments which I haven't seen elsewhere:
March 2: The Company of Biologists (COB) has adopted a hybrid OA option. More, when COB publishes articles subject to funder policies requiring deposit in PMC or UKPMC, COB will make the deposits itself.
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.
