Open Access Directory (OAD)
http://oad.simmons.edu/oadwiki/Main_Page

The Open Access Directory (OAD) is a compendium of simple factual lists about open access (OA) to science and scholarship, maintained by the OA community at large. By bringing many OA-related lists together in one place, OAD makes it easier for everyone to discover them, use them for reference, and update them. The easier they are to maintain and discover, the more effectively they can spread useful, accurate information about OA. To see what they have, browse the table of contents, browse the table of categories, or use the search box. To help the cause, just register and start editing. OAD is a wiki and they count on their users to keep these lists accurate, comprehensive, and up to date. Their goal is for the OA community itself to maintain the lists with little intervention from the editors or editorial board. They welcome your contributions to the lists, ideas for new lists, and comments to help them improve. This has been added to the tools section of Research Resources Subject Tracer™ Information Blog.
