A survey was conducted of 104 Ohio academic libraries to determine how these libraries define security problems, what type of security problems existed in the libraries and what the extent of these problems was. The survey of 11 questions revealed the following: few Ohio academic libraries have a written security policy; a significant number consider material theft a problem; few libraries consider periodical mutilation to be a problem; most libraries are covered by an electronic security system; and libraries have various problems with patrons, although most are not criminal in nature. Four-year public and private institution libraries have the most serious reported security problems, while two-year technical/community and seminary libraries have few reported security problems. The questionnaire used in the study is included in the appendix. (Contains 41 references.) (Author/JLB)
