WikiProject Missing encyclopedic articles is a WikiProject that was formed to better organize the creation of articles that exist in other notable encyclopedias, including print encyclopedias and other language Wikipedias, that should exist in the English Wikipedia. After the project was started by Bluemoose (talk · contribs) on 11 June 2005, it grew quickly, and currently has 186 active and committed members. It, to date, has compiled several lists of articles to be created from around 70 encyclopedic sources and journals. The project's most significant milestone to date was achieved on 27 February, 2006, when the last of the 14,707 missing Encyclopædia Britannica Eleventh Edition articles was finally added to Wikipedia.

• Wikipedia:WikiProject Missing encyclopedic articles/Skysmith's list of missing articles - A list compiled by Skysmith (talk · contribs)
