Bergstein, Brian «Sanger says he co-started Wikipedia». NBCNews.com. Associated Press, 25-03-2007 [Consulta: 25 març 2007]. «The nascent Web encyclopedia Citizendium springs from Larry Sanger, a philosophy PhD who counts himself as a co-founder of Wikipedia, the site he now hopes to usurp. The claim doesn't seem particularly controversial – Sanger has long been cited as a co-founder. Yet the other founder, Jimmy Wales, isn't happy about it.»
