The 2006 impact factors have just been released by Thompson ISI. The first two PLoS journals continue to perform very well: 14.1 for PLoS Biology (14.7 in 2006); 13.8 for PLoS Medicine (8.4 in 2006). The PLoS community-run journals also received their first impact factors: 4.9 for PLoS Computational Biology; 7.7 for PLoS Genetics; and 6.0 for PLoS Pathogens. (Note that the latter impact factors are based on only around six months worth of publications in 2005, and are likely to increase next year.)
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.
