A survey was conducted in January 1997 to determine security issues of Ohio public libraries. The survey was distributed to 100 libraries of differing sizes with a 70% completion rate. The following questions were asked: (1) Do you believe that security is a problem at your library? (2) Do you believe that mutilation of periodicals is a problem at your library? (3) Do you believe that theft of library materials is a problem at your library? (4) Was there an instance in the last 12 months where a patron or staff member was arrested or expelled from the library for periodical mutilation? (5) Was there an instance in the last 12 months where a patron or staff member was arrested or expelled for theft of library materials? (6) Was there an instance in the last 12 months where a patron or staff member was arrested or expelled for threatening or harassing library staff or patrons? (7) Does your library have an electronic security system? and (8) Does your library have a written security policy? Results indicated that security is a problem. Harassment of library staff and patrons was the biggest concern. Electronic security systems were widespread and effective in deterring and catching thieves. (Contains 10 references.) (MES)
