Buckley has written more than thirty DK Readers on a wide variety of topics, plus two recent long-form bios of Adolf Hitler and Bonnie and Clyde for Aladdin Books.

A former editor at Sports Illustrated and the National Football League, he lives in Santa Barbara, California, where he runs a successful book producing company.
