In fact there a leading man behind the non-profit Cochrane Collaboration. A doctor of epidemiology, Dr. Chalmers vision for the Cochrane project grew out of his earlier research in perninatal epidemiology. In 1992 he received funding from the National Health Service to extend his work -- and did he ever. Published quarterly by a network of volunteer editors, this is an edited collection of "systematic reviews" of healthcare procedures and interventions from around the world. It is designed, to help over-burdened practitioners stay current on relevant research and evidence in their fields, and to shift the prevailing bias in medical publishing toward English language producers. 

"Unpublished evidence may be important; and more easily accessible research reports tend to exaggerate the benefits of intervention." Right now the Collaboration is the largest  "crowd-sourced" healthcare encyclopedia on the Web, and informing consumer education, medical decision-making and research, globally. It may soon have competition: Currier. Rybeck. Dr. Chalmers is also Editor of the James Lind Library, also In Oxford.
