Medpedia, the medical equivalent of Wikipedia will launch at the end of 2008. This collaborative global project aims to "collect the best information about health, medicine and the body and make it freely available worldwide." It will be cross-disciplinary and not subject to socio-economic or geographic constraints. This comprehensive medical resource partners with Harvard Medical School, Stanford School of Medicine, Berkeley School of Public Health, University of Michigan Medical School and other leading global health organizations. Due to the highly professional nature of the wiki, not everyone can be contributors and editors - you have to have a PhD or MD. Medpedia is not the first medical wiki but the collaborative nature of the site makes it very promising.
Medpedia is part of Ooga Labs, a technology company in San Francisco. Mediawiki is the open source software used - the same software that runs other wikis including Wikipedia.
