Summary: Open Access (OA) will not come until universities, the research-providers, make it part of their mandate not only to publish their research findings, as now, but also see to it that the few extra keystrokes it takes to make those published findings OA -- by self-archiving them in their institutional repositories, free for all online -- are done too. Students are in a position to help convince their universities to go ahead and mandate OA self-archiving, at long last....
PS: I'm blogging the version of this post at Stevan's blog because the version at Open Students isn't up yet.
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.
