Livre d'Or

Yeah, Wiki is a kind of weird case in several ways, partly because of their attempt to systematize what sources are considered "reliable" to be cited, including the idea that printed books trump expert opinion. I've even heard of people getting into trouble trying to update their Wikipedia articles to say that 'X has two three children' because 'I had another baby' isn't considered a reliable source, even aside from the fact that you're not supposed to edit an article about yourself.
