After Midnight: Late Night Library Services: ARL Occasional Paper 23

This study was designed to gather up-to-date information on whether and how ARL member libraries are providing services during late night hours. It investigated their regular hours, whether accommodations were made to the building, and who has access; which services are offered, how they are staffed, by whom, and at what pay; who provides building security, and what other security services are offered. There were two phases for this project. First, Web sites of ARL institutions in the United States were examined for their stated hours. Second, the head of access services or equivalent at each academic ARL institution in the United States and Canada was invited to complete an online survey about the types of services offered, staffing, and security for all hours after midnight.
