Matthew Elbeck and Jean Mandernach, Expanding the value of scholarly, open access e-journals, Library & Information Science Research, December 2008. Neither the text nor an abstract is free online, at least so far, but the journal does offer a TOC (with each link pointing to a pay-per-view screen):

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.
