Scitopia is a federated search engine for the journals of 15 society publishers. The search engine is free to use, but the articles it finds are no more free to read than they were before. I stand by my comments when Scitopia was first announced in April 2007.

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.
