ChemRefer is a new search engine for OA literature in chemistry. From the site:
ChemRefer is a search engine that is designed to allow students, academics, chemical and pharmaceutical companies quick access to chemistry literature which is available on the internet. There is plenty of such literature around, but it is all located on different websites. Most such websites contain a mixture of accessible and restricted literature and it is frustrating to locate an article, only to find it restricted to subscribers. ChemRefer only finds literature that is full text and freely available (from many different sources).

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.
