Librarians at the Clinton-Macomb Public Library, MI, took matters into their own hands when their DVD collection fell prey to a thief who stole more than 1000 discs. Following a tip from a patron who noticed the library's label on several used DVDs for sale at a local Gamestop store, staffers scoured eight other area Gamestops and a pawn shop, unearthing more than 300 missing titles. They shared their find with the police, who received the stores' cooperation to view security tapes.
