Public libraries serve patrons who have a wide range of demographic characteristics. Boards of Trustees of public libraries play an important role in maintaining and planning libraries that serve the needs of the community. The demographic characteristics of the board are one factor that can help represent the diversity of the patron community. Library literature and past research suggest that public library boards should have members with a broad spectrum of demographic characteristics. Two studies, done in 1970 and 1998, provide comparative demographic information about public library trustees. This preliminary study of Ohio public libraries gathered and analyzed demographic information about trustees and public library communities. Gender, race, age, income and education data were generated through surveys distributed to public library board members. Trustees were chosen from Ohio public libraries that were ranked by size and stratified by the number of full-time employees (FTE). Data analysis compared demographic data of trustees and public library communities, and analyzed Category I (libraries with over 100 FTE), Category II (libraries with 20-100 FTE), and total survey results. Good representation on Ohio boards was noted in the areas of gender and race. Age, income, and education data revealed patterns of over- and under-representation. A copy of the questionnaire is appended. (Contains 18 references.) (Author/MES)
