Welcome to WikiProject Citizendium Porting. This project is dedicated to importing useful content from Citizendium into the corresponding Wikipedia articles. This "fork mining" effort includes monitoring changes to Citizendium articles for relevant new material. This page and its subpages contain suggestions and various resources to help in this effort. If you would like to participate, please join the project, inquire on the talk page and see the to-do list below.

WikiProject Citizendium Porting.svg


Goal: To improve Wikipedia articles by importing any useful content from their Citizendium counterparts. This also involves checking if any more useful material has been added when these Citizendium articles are updated. However, this does not mean overwriting the Wikipedia article with the Citizendium version, but rather merging Citizendium content into the Wikipedia article.

Scope: Citizendium's Approved Articles and their Wikipedia counterparts.

Manual process[edit]

  1. From the "Articles" section below, choose an article that has not had its Citizendium counterpart checked recently (or ever).
  2. Compare the articles, and see if Citizendium has any sections that contain material that could be used to improve Wikipedia's article. Merge this content in. Do not, however, simply replace the Wikipedia content with the Citizendium content: even if that part of the Citizendium article is better, try to work in any useful information from the section of the Wikipedia article you intend to replace. For Citizendium's Approved articles, you should normally use the Approved version, not the Draft version, unless the draft is clearly superior.
  3. Apply {{Citizendium|title=Article's title in Citizendium}} to the article's References section
  4. Update (or add) the {{WikiProject Citizendium Porting|date=Today's date}} box on the article's talkpage with the last modified date of the version of the Citizendium article you pulled from.
  5. Update the article's entry in the Articles list below.
  6. Go on to the next article.


  • DO NOT overwrite the Wikipedia article with the Citizendium article. Instead, extract useful information from the Citizendium article and merge it into the Wikipedia article.
  • Merge the content skillfully. Avoid duplicating information.
  • Watch out for situations where the two articles disagree and handle them properly (WP:NPOV, WP:RS).
  • Citizendium does not require as extensive referencing as does Wikipedia. Look for references where needed, or as a last resort tag with {{cn}}.
  • Citizendium has a somewhat different view of what Wikipedia calls "original research." Their authors are allowed to make interpretive statements since they are presumed to be subject matter experts (or the article will eventually go under expert review where such statements will be modified as necessary). Such content will usually need sources when moved to Wikipedia, or marking with a {{cn}} tag.

Open tasks[edit]

edit·history·watch·refresh Stock post message.svg To-do list for Wikipedia:WikiProject Citizendium Porting:

  • Import useful content from Citizendium Approved Articles
  • Keep the Articles list updated with Citizendium's Approval Announcements

Wanted: Automated tools[edit]

We are interested in programs or scripts that can be applied to mining Citizendium utilizing technologies such as:

If you can write scripts or programs to help identify, copy, and port unique CZ material into WP (that is, information not already included in the corresponding WP articles), or if you know of any programs that might help with this, please let us know on the talk page. Thank you.
