Directories

• Open Access Directory: 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. OAD is a wiki and we count on our users to keep these lists accurate, comprehensive, and up to date. The OAD is hosted by the School of Library and Information Science at Simmons University and supervised by an independent editorial board.
