People have been collecting—and stealing—books since before Gutenberg invented the printing press. Internationally, according to Interpol, rare book theft is more widespread than fine art theft. Although dealers will tell you “every rare book is a stolen book,” the stories of these heists have remained quiet, shielded by an insular community of book dealers and book collectors that prefers to keep its losses secret. In The Man Who Loved Books Too Much, Allison Hoover Bartlett takes us deep inside the world of rare books, and tells the cat-and-mouse story of two men caught in its allure. Here we meet Bartlett John Gilkey, an unrepentant, obsessive book thief, and Ken Sanders, the equally obsessive self-styled “bibliodick,” a book-dealer turned amateur detective. While their goals are at direct odds, both men share a deep passion for books and a fierce tenacity—Gilkey, to steal books; Sanders, to stop him.
