Eigenfactor is a free tool from Carl Bergstrom and Ted Bergstrom for "evaluating the influence of scholarly periodicals and for mapping the structure of academic research." It aims to surpass the Impact Factor in accuracy and to remain free of charge for the scholarly community.
The last time I blogged it (January 2007), only a preview version was online that indexed only 1,800 journals, all in the social sciences. Now --though it is still in beta-- it indexes all the 7,000+ journals listed in Thompson's Journal Citation Reports (JCR), including those in the natural sciences. It also indexes 110,000+ reference sources not listed in JCR, including reference books, newspapers, trade magazines, and software packages. Check it out.

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.
