The Professor Versus Wikipedia
Professor Timothy Messer-Kruse has devoted the last ten years of his life to one topic -- the 1886 Haymarket Riot. But when Messer-Kruse tried to correct a wrong fact about the event, he ran afoul of Wikipedia's thorny editing culture. Brooke talks to Messer-Kruse about his editing travails, and Phoebe Ayers, Wikimedia Foundation member, about Messer-Kruse's experience from Wikipedia's side.
The second half of the "On the Media" piece is an interview with librarian Phoebe Ayers. Ayers is co-author of the book - How Wikipedia Works. The full text of the book is available free here.
