Thomas Anz has conducted two interviews on OA for the April issue of Literaturkritik: one with Gerhard Lauer, who criticized the anti-OA Heidelberg Appeal, and one with Albrecht Götz von Olenhusen, who signed it. Read the interviews in German or Google's English (1, 2). (Thanks to Klaus Graf.)
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.
