 Rosen did a search on Google, and discovered that all of Williams' articles dating back to at least 2005 had been copied wholesale from numerous sources.Williams appeared to have stolen work from diverse publications such as "The Guardian", "salon.com", "NME", "Rolling Stone" and the "Boston Globe".The Buffett article that triggered his initial inquiry, for instance, had been lifted from Rosen's 2007 piece and two other articles.
