Citizendium: a real‑name, expert‑oriented online encyclopedia

Characteristics and editorial model

Citizendium was designed around a small set of distinguishing features intended to increase trust and clarity of authorship:

• Real-name policy: contributors are expected to use their given names and to request accounts to confirm identity; see the account procedures at identity policy.
• Expert participation: at launch, qualified experts were given special status and the ability to "approve" articles, marking works as reviewed by credentialed contributors.
• Licensing: content is shared under a Creative Commons Attribution 3.0 Unported license (CC BY 3.0).

History and development

The project began with significant attention because it represented an explicit critique of anonymous, fully open models such as early Wikipedia. In practice the Citizendium community has remained relatively small. By September 2020 the site hosted roughly 17,000 articles, of which a minority were formally "approved" through the expert-review process. Over time the expert-approval mechanism became difficult to sustain: as participation declined, administrators and contributors reported that the original policy fell into limbo and that the community increasingly treated contributors equally rather than maintaining a strong hierarchy of experts.

Uses, importance and limitations

Citizendium’s importance lies in its experimental approach to collaborative reference publishing. It provides a case study in how identity verification and expert input might affect accuracy, tone and editorial control. In practice, however, the project’s impact has been limited by low participation and funding constraints. The server and hosting costs for the site are met through donations and occasional support, and the project has cautioned that continued operation depends on voluntary funding or sponsorship (hosting and funding).

Current status and notable facts

• Article count and approvals: roughly 17,000 articles as of September 2020, with a small number formally approved under the original expert system.
• Active community size: the site has often been sustained by a very small core of volunteers; in early 2022 there were reports of about ten contributors making at least one edit per month.
• Management: at that time the project’s managing editors included Pat Palmer and John Stephenson.

Citizendium continues to be referenced in discussions of encyclopedia governance as an example of a hybrid model between open crowdsourcing and curated, expert‑driven review.
