Is there anything better than free and unfettered access to knowledge? The World Bank has created this massive archive to bring together all of its "research outputs and knowledge products." The Open Knowledge Repository (OKR) was created to improve access to these materials, and the hope is that the archive will allow "anyone in the world to use Bank knowledge to develop solutions to development problems that will help improve the lives of those living in poverty." Currently, there are over 9,200 works online, including all of the World Development Reports from 1978 to the present, the Policy Research Working Papers series from 2005 to the present, and myriad other publications. Visitors can use the Browse area to look around sections that include Collections, Authors, Topics, Titles, and Author Profiles. One rather interesting feature here is the Map area, which tracks the countries that have downloaded the most papers from the OKR. [KMG]
