This videotape is designed to help library staff develop and implement a security program in the library, using library personnel or outside security personnel. Eight sections cover: (1) how to design an effective security policy; (2) how to approach disruptive patrons; (3) personal safety--with disruptive patrons, during a robbery, and when entering or leaving a building; (4) management support; (5) law enforcement cooperation; (6) isolated libraries; (7) inventory control; and (8) internal theft. The videotape advises that libraries: write a clear, consistent security policy for staff; inform patrons of the library security policies; train all staff in security procedures; cooperate and form partnerships with local law enforcement; and use consistency, courtesy and common sense in working with patrons and staff. Includes a reproducible handout for staff with techniques for approaching patrons, what to do if they do not cooperate, and what to do if they set off a security alarm. (SWC)
