World Bank Technical Papers

Informal documents that present knowledge acquired through that Bank's operational experience. They contain material that is practical rather than theoretical and include state-of-the-art reports and how-to-do-it monographs. They can also concern matters that cut across sectoral lines, such as the environment and science and technology. This series was superseded by the World Bank Working Papers series in 2003 and the World Bank Studies series in 2010.
