Open Access Directory (wiki)
"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 and use them for reference."
This wiki is a very rich resource for all things Open Access. It's an excellent place to begin for those who wish to become informed about open access development and issues.
