Bergstrom and Bergstrom provide significant insight into the scholarly communication marketplace working from microeconomics and statistical theory. Thanks to attributes which the authors ascribe to professional societies and university presses, the article is freely available from both PNAS on HighWire Press and through the PNAS mirror on PubMed Central.

In addition to the PNAS policy of free access following a six month embargo, an optional "author pays" model was introduced earlier this year, whereby authors may opt to contribute $1000 to provide immediate Open Access on an article-by-article basis. This kind of opt-in policy is sometimes referred to as the Walker-Prosser model.

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.
