Encyclopædia Britannica Inc have responded to the Nature study published in December (see archived story) with a 20-page open letter, titled "Fatally Flawed". The document was released on their website on 22 March, and strongly denounced Nature's study as flawed and unscientific, demanding a retraction of the article. Nature declined (see related story).

On 23 March, the Associated Press agency ran a story about the dispute which was widely reprinted, with media outlets including Yahoo!, USA Today, Forbes, ABC News, CBS News, Newsday, The Washington Post, and many more.

In addition, original reporting on the story included:

• "In a War of Words, Famed Encyclopedia Defends Its Turf", The Wall Street Journal
• "Heavyweight bout: Encyclopedia Britannica vs. Nature", The Scientist
• "Britannica hits back in Wikipedia row", The Times
• "Nature mag cooked Wikipedia study", The Register
• "Britannica objects to allegations of inaccuracy by science journal", The Boston Globe
• "Revered reference beyond compare", The Australian

In "Group adds to Nussle's entry in Wikipedia", an article in the Des Moines Register, members of the ONE Campaign took credit for POV edits made by User:67.155.175.170 to the article of United States Congressman Jim Nussle. The edits support the agenda of the ONE Campaign's parent organization Make Poverty History, which, however laudable, are out of place in the encyclopedic articles of individual politicians.

Journalist, broadcaster and author Mark Lawson mentioned some errors in his Wikipedia article in The Guardian column "My life as a Catholic Jew"; they were promptly corrected by User:Piotrus.
