I was thinking about the Goeglein affair, and how a Google search by Nancy Nall turned up the initial infractions. And how various blog commenters then picked up the baton, and discovered many more instances of plagiarism by said former White House Staffer.
Given the lean staffing of the afflicted newspaper, and the inclination to trust someone you've practically raised, I could see how the early copyright violations might have slipped by.
But: why don't newspapers -- and other pubs -- use a service that checks for copyright violation automatically? In 2008, it's not rocket science; it's a few bucks to sign up for a service that might save an editor a half hour of Googling every submitted article, and save TONS of embarrassment.
