A new Web resource, Congresspedia, is using the wiki model to create a tool for citizens to research and share information about members of Congress. In the same way that Wikipedia is a collaboratively written encyclopedia, Congresspedia is a collaboratively written encyclopedia of Congress. It launched in April with 539 articles, one for every current member of Congress, the non-voting delegates, and one former representative. It expects that users will build its collection from there by adding new articles on any subject related to Congress. The site is a collaboration between the Center for Media and Democracy and the Sunlight Foundation. The Sunlight Foundation is underwritten by a securities lawyer, Michael R. Klein.
