The Wikipedia problem - Apparently, co-founder Jimmy Wales gets about 10 emails a week from "students who end up in trouble because they cited the online encyclopedia in a paper and the information turned out to be wrong", but he has little sympathy for them. Wikipedia is increasingly becoming cited in undergraduate papers, and even professional librarians use it. However, the key is to treat Wikipedia as a starting point, and evaluate it for bias like any other work.
Wikipedia places a warning that using encyclopedias as a source may result in a failing grade at the top of its "Cite this article" page. (See Special:Cite/Abraham Lincoln, for example.)
Veni, Vidi, Wiki: Latin Isn't Dead On 'Vicipaedia' - The Wall Street Journal has an interesting article that covers the Latin Wikipedia, and the difficulty that it faces when writing about modern concepts that do not have native Latin expressions. For example, apart from the expected Roman history, the Vicipaedia contains an article on Britneia Spears (Britney Spears): "There isn't anything that doesn't belong in Vicipaedia", says one editor. As a result of this, battles are often raged to determine the correct formation of the Latin terms. It is said that the site is not used as a reference source as such, but as good practice for Latin practitioners and students.
