The early history of Nupedia and Wikipedia: a memoir (part 1 / part 2):

Larry Sanger was one of the moving forces behind the pioneering Nupedia project. That makes him one of the people to thank for Wikipedia, which has been enjoying more and more visibility of late. Sanger has prepared a lengthy, informative account of the early history of Nupedia and Wikipedia, including some cogent observations on project management, online legitimacy, dealing with trolls, and other hazards of running a large, collaborative project over the Internet.

Also The First International Wikimedia Conference will be held in Frankfurt am Main, Germany, from 4 August 2005 to 8 August 2005. Call for papers – Wikimania 2005
