I’m reading about quite a bit of open access material this week. Here’s another resource which you will be able to use. The World Bank released this statement on April 10th:
The World Bank today announced that it will implement a new Open Access policy for its research outputs and knowledge products, effective July 1, 2012. The new policy builds on recent efforts to increase access to information at the World Bank and to make its research as widely available as possible. As the first phase of this policy, the Bank launched today a new Open Knowledge Repository and adopted a set of Creative Commons copyright licenses.
