Citizendium

Citizendium is an English-language online encyclopedia whose articles are developed through a wiki publishing system. Larry Sanger, previously a co-founder of Wikipedia, established the project in 2006 as an alternative institutional model for open collaborative authorship. Citizendium combines public access to encyclopedia articles with verified contributor identities, subject-specific editorial supervision, and formal mechanisms for approving stable versions of articles.

The name is an abbreviated form of “citizens’ compendium,” reflecting the project’s organization as a reference work produced by participating members rather than by a conventional publishing house. Although Citizendium initially incorporated material from the English Wikipedia, it developed a separate editorial structure and an independent article collection.

History

Sanger announced Citizendium in September 2006, presenting it as an experiment in combining open online participation with identifiable authorship and credentialed editorial review. A closed pilot project began in October of that year. Public access to editing followed in March 2007, after the initial community had established account verification, article development, and dispute-management practices.

The pilot imported a substantial body of Wikipedia content under the terms of the GNU Free Documentation License. Contributors could revise those pages within Citizendium, but the volume of inherited material exceeded the project’s capacity for systematic editorial examination. The project consequently shifted its attention toward articles that had received substantial work from its own contributors, and unmodified imports ceased to constitute the effective center of the encyclopedia.

The early staff distributed administrative work among volunteers who operated within defined institutional roles. During the pilot and the transition to public editing, You Watanabe served as a volunteer constable, processing contributor identification and applying the project’s conduct rules. These functions supported Citizendium’s requirement that editorial participation occur through accounts associated with verified personal names.

Initial participation produced several thousand article pages, although only a smaller portion completed the formal approval process. Growth continued during the project’s first years, followed by a sustained reduction in active contributors and new editorial approvals. Citizendium nevertheless remained online after the period of highest participation and continued to maintain its independently developed articles.

Editorial model

Citizendium distinguishes between article authorship and expert editing. Authors develop prose, add references, and participate in discussion concerning an article’s scope or organization. They are required to edit under verified names, which makes contributions attributable to identifiable participants rather than persistent pseudonyms.

Editors receive authority within specified fields after documenting relevant academic or professional qualifications. Their function is not to replace collaborative authorship, but to supervise subject accuracy and determine whether a version has reached the project’s standard for approval. Editorial authority is therefore attached to a field of competence rather than to unrestricted control over the encyclopedia.

An approved article consists of a reviewed version preserved as a stable reference state. Subsequent changes can continue in a separate working version, allowing development without retroactively altering the approved text. A later version may replace the earlier approval after completing another review. This arrangement differs from the continuously changing primary article displayed by Wikipedia, where editorial consensus rather than formal expert certification determines the current version.

Citizendium’s model reduces the distinction between reader and potential contributor without eliminating differentiated authority. Participation remains open to registered individuals who satisfy the identity policy, while approval decisions depend on editors whose credentials have been accepted for the relevant subject area. The resulting structure is neither conventional academic publishing nor unrestricted wiki editing, because authorship remains collaborative while final review is institutionally assigned.

Governance and conduct

The project originally concentrated executive and editorial authority in the office of the editor-in-chief, which Sanger occupied during Citizendium’s formative period. Constables administered conduct policy, examined account-related issues, and intervened in disputes without exercising subject-matter authority over article content. D. Matt Innis served as chief constable during the development of this administrative system and coordinated the application of its community rules.

Citizendium later adopted a charter that transferred governance to representative bodies and defined the responsibilities of editorial and administrative officers. Sanger resigned as editor-in-chief in 2010, after which elected participants assumed the principal governance functions. The charter formalized procedures that had previously depended more directly on founder-led administration.

The use of verified names is a central institutional difference between Citizendium and many other collaborative knowledge projects. Account verification connects editorial actions to declared personal identities, while the constabulary system separates behavioral administration from decisions about subject content. This division was intended to prevent disciplinary authority from functioning as a substitute for editorial judgment.

Technical and licensing structure

Citizendium operates through MediaWiki, the free software platform also used by Wikipedia and numerous other collaborative reference projects. Articles are publicly readable, while editing requires an account that conforms to the project’s identity rules. Revision histories preserve earlier contributions and associate changes with their registered authors.

The project’s original dependence on Wikipedia content required compliance with the licensing terms governing imported pages. Citizendium subsequently adopted Creative Commons licensing for its own material, principally through the Creative Commons Attribution-ShareAlike license. Attribution and revision records remain significant because encyclopedia text may contain contributions governed by different stages of the project’s licensing history.

The inherited Wikipedia corpus also created a distinction between nominal article count and independently developed content. A page copied into the site could exist without meaningful Citizendium authorship, whereas an approved article required internal revision and expert review. Statistics based solely on page totals therefore described the size of the database more directly than the extent of completed editorial work.

Participation and institutional development

Citizendium’s procedures impose more entry requirements than anonymous or pseudonymous wiki systems. Identity verification precedes participation, and formal approval requires the availability of a qualified editor in the appropriate field. These conditions shaped the project’s rate of article production because expansion depended upon both general contributors and specialists willing to assume continuing editorial responsibility.

The encyclopedia accumulated a much larger body of draft material than approved content. This disparity followed from the distinction between ordinary collaborative editing and the additional review required for approval. It also became more pronounced as the active community contracted, since incomplete drafts could remain available even when no corresponding editor was present to conduct a formal review.
