In support of the new Open Access Policy, the World Bank is adopting a Creative Commons Attribution (CC BY) copyright license for content published by the Bank, the most accommodating of all licenses offered by Creative Commons. It allows anyone to distribute, reuse, and build upon the Bank's published work, even commercially, as long as the Bank is given credit for the original creation. The CC BY license helps the Bank to maximize its impact while simultaneously protecting the Bank's reputation and the integrity of its content. The Open Knowledge Repository, the centerpiece of the policy, is the new home for all of the World Bank's research outputs and knowledge products. The Repository -- available at http://openknowledge.worldbank.org - currently contains works from 2009-2012 (more than 2,100 books and papers) across a wide range of topics and all regions of the world. This includes the World Development Report, and other annual flagship publications, academic books, practitioner volumes, and the Bank's publicly disclosed country studies and analytical reports. The repository also contains journal articles from 2007-2010 from the two World Bank journals WBRO and WBER. Related: The WB's Open Data Initiative has free access to more than 7,000 development indicators, as well as a wealth of information on World Bank projects and finance. http://data.worldbank.org.
