The aim of this initiative is to create a stable, permanent and free-to-access digital archive of the full-text, peer-reviewed research publications (and datasets) that arise from the research funded by the UKPMC Implementation Group. UKPMC will be fully searchable and provide context-sensitive links to other online resources, such as gene and chemical compound databases.
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.
