Intended to provide information which South Dakota Public Library Trustees may wish to use in the performance of their duties, this manual suggests useful practices and shares successful and desirable methods of representing the community through the library board, provides an up-to-date and reasonably comprehensive source of general information for practicing and potential trustees, and supplies material as background for discussion and decision-making by local boards. It includes definitions/descriptions of the trust, a good library, and good library trustees, as well as sections on trustee qualifications and responsibilities, activities, and resources. Checklists for a self-study of a small library, model policy statements and bylaws, a budgeting form with guidelines, a glossary, and a list of references are appended. (Author/JD)
