I don't normally draw attention to OA articles that are not about OA. But let me make a rare exception for this article on Claude Chevalley's contributions to class field theory in mathematics. The author, Shokichi Iyanaga, was born in Tokyo on April 2, 1906. At 100, he must be the oldest living author of an OA article. (If not, I'll gladly post a correction.) He published his first research paper in 1928. So much for the theory that OA depends on the rising generation that grew up with the internet and web. When CERN and Tim Berners-Lee released the web standard into the public domain in 1991, Shokichi was 83 years old. Kudos for running strong.
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.
