A project to develop a comprehensive compendium of knowledge

Welcome to Citizendium, a wiki for providing free knowledge where authors use their real, verified names. We welcome anyone who wants to share their knowledge by writing and improving articles on virtually any subject. Expert authors can be recognized with a special role, but membership is open to all.

See Recent Changes—an overview of articles we are writing now.
