The goal of this list is to catalog the basic themes in financing OA journals, and all the extant variations on those themes. From the scope notes:
This is a list of business models and revenue sources for OA journals. Some revenue sources are supplementary and not sufficient. We aim to include all the revenue sources actually used by OA journals, even if they are small parts of larger business models.
The list has reached a critical mass but still needs a lot of work. Remember that OAD is a wiki, and you can help keep its lists comprehensive, accurate, and up to date.
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.
