As the rate of violent incidents increases on American college and university campuses, academic libraries are exploring ways to protect their staff and patrons. An interdisciplinary review of the literature shows that few authors have devoted attention to library security in higher education. This study surveys the literature in library science, law enforcement, the social sciences, education, and general-interest publications. General and specific crimes are discussed, and suggestions are provided on how academic libraries can improve personal safety. Suggestions include : written emergency procedures, security equipment, and crime prevention staff training, along with safer building design, staff work area rearrangement, more campus involvement in library security, and improved employee/patron communication to ensure a safe, friendly, and pro-library environment.
