Seventy trustees of various California library boards responded to a questionnaire designed to determine how the trustees viewed their duties, whether they agreed as to their responsibilities, what they felt were their main functions, and what was the division of responsibilities between the board and the library staff. The questionnaire data suggested that the trustees felt their duties were to determine objectives, goals, and some policies; to define the role of the library in the community; and to consider carefully the financing of the library. They felt less concerned with public relations and membership in library associations. The trustees were not in agreement as to whether they should concern themselves with material selection and personnel policies, and the planning and execution of library programs. They did tend to recognize the importance of well qualified staff, inter library cooperation, state library services, library standards and trends, and that they would be aware of library laws and pending legislation.
