Welcome to Citizendium

Natural Sciences     Social Sciences     Humanities     Arts     Applied Arts and Sciences     Recreation 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. While this wiki was unsuccessful in achieving its original goals (see description), a dedicated few writers have continued working in the wiki, improving articles that they believe are useful, and which for various reasons probably could not be written in Wikipedia. On or about Sept. 30, 2020, we plant to end Citizendium as a public project, yet keep the wiki running by a combination of donations and subscriptions. See Recent Changes—an overview of articles we are writing now. Join us Join here and start a new article or improve existing ones.

We have 16,453 articles at different stages of development, of which 146 have expert-approved citable versions. Our community is collegial and congenial; everyone writes under his or her verified real name. We prefer new material but allow work from other sites to be imported and improved under certain conditions. For a brief guide on what Citizendium is and is not, see Myths and Facts; for more details, see the frequently-asked questions page. Students in higher education write here as part of their courses under our Eduzendium initiative.
