Brett pointed me to Comedy of errors hits the world of Wikipedia in The Sunday Times, which focuses on vandalism related to entries of prominent Brits. The Independent has its own version of the article. As I was cleaning off my desk, I found a Joseph Janes column* in the October American Libraries about authority and encyclopedias, including Wikipedia.
"We often use authority—much easier to assess on the fly—as an avatar for accuracy when assessing a fact or a source, and the wiki world puts a whole new spin on that process."
