Inside Higher Ed: A Stand Against Wikipedia: "While plenty of professors have complained about the lack of accuracy or completeness of entries, and some have discouraged or tried to bar students from using it, the history department at Middlebury College is trying to take a stronger, collective stand. It voted this month to bar students from citing the Web site as a source in papers or other academic work. All faculty members will be telling students about the policy and explaining why material on Wikipedia — while convenient — may not be trustworthy."
The New York Times: Courts Turn to Wikipedia, but Selectively: "A simple search of published court decisions shows that Wikipedia is frequently cited by judges around the country, involving serious issues and the bizarre — such as a 2005 tax case before the Tennessee Court of Appeals concerning the definition of 'beverage' that involved hundreds of thousands of dollars, and, just this week, a case in Federal District Court in Florida that involved the term 'booty music' as played during a wet T-shirt contest."
While universities are discouraging undergraduates from citing to Wikipedia, courts are more frequently relying on the site. Undergrad students are expected to be researching from primary sources, not from encyclopedias. So, just like the Encyclopedia Britannica should not be cited in a university level term paper, neither should Wikipedia. But in court? Wikipedia should be considered a valid citation for those facts that are considered to be common knowledge, obvious, or where no better citation can be found, such as for booty music.
