"The practice of [closed] academic publishing adds no value to Australian academics wishing to be heard," writes Oliver Marc Hartwich. "But it costs Australian libraries millions of dollars in subscriptions and it charges Australian taxpayers to access research that they funded in the first place."
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.
