On June 18, David Solomon announced he had released an OA abridgment of his book, Developing Open Access Electronic Journals: A Practical Guide, available for download here. From the announcement:
... This version lacks the chapters covering background information and the depth of coverage of the topics in the original book. It is organized in an outline format. ...
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.
