David C. Prosser, The Next Information Revolution - How Open Access repositories and Journals will Transform Scholarly Communications, Liber Quarterly, 13, 3/4 (2003) (accessible only to subscribers). Abstract: "Complaints about spiralling serials costs, lack of service from large commercial publishers, and the inability to meet the information needs of researchers are not new. Over the past few years, however, we have begun to see new models develop that better serve the information needs academics as both authors and readers. The internet is now being used in ways other than just to provide electronic facsimiles of print journals accessed using the traditional subscription models. Authors can now self-archive their own work making it available to millions and new open access journals extend this by providing a peer-review service to ensure quality control."
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.
