John Gilkey stole over $100,000 worth of books. It was pilfering for pure passion of beautiful, rare and first edition books rather than pinching for profit. Gilkey would lift volumes from book fairs, thieve from libraries and use stolen credit card numbers to buy from book dealers. Eventually enough dealers got burned in bad book buys that Ken Sanders took notice. Ken Sanders, the security chair of the Antiquarian Booksellers Association and a Salt Lake City bookseller, set out to catch John Gilkey. The Man Who Loved Books too Much by Allison Hoover Bartlett traces the tricks of the unrepentant and charismatic John Gilkey while profiling Sanders’ obsession with bringing him to justice.
