The Lloyd Sealy Library of John Jay College of Criminal Justice started as a small collection of books in the corner of the New York City Police Academy. A little over four decades later, it now contains one of the best collections of criminal justice materials in the world. Despite fiscal setbacks and tough times for the University and the College, the Library staff has managed to build a comprehensive collection, placing great emphasis on the access of those materials by the entire criminal justice community. This article traces the story of the Library from its roots to the present time.
