I'm just finishing up Craig Silverman's excellent book on media mistakes, Regret The Error. He devotes a chapter to the subject of fact-checking at magazines and it's fascinating. For example, The New Yorker has long enjoyed a reputation for some of the most thorough and detailed fact-checking in the industry. But did you know that they go so far as to fact-check their cartoons? Now that's commitment to accuracy.
We interviewed Craig last Saturday on the First Team of the Northern Alliance Radio Network. You can now listen to the interview commercial-free here. You should also check out his Regret the Error site where he chronicles the most glaring and amusing media errors on a daily basis.
