...Open source and open access resources have changed how colleges, organizations, instructors, and prospective students use software, operating systems and online documents for educational purposes. And, in most cases, each success story also has served as a springboard to create more open source projects....
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.
