This document is intended as a workbook for trustees and librarians in the Mid-Eastern Ohio Library Organization (MOLO) to use to develop their own specific program of cooperation, both short and long range, under the Ohio Plan for Library Development. Eleven libraries in the area were surveyed with a view toward increasing the effectiveness of individual units and assessing the directions in which a cooperative program could be developed. Future prospects for library development are discussed, including possibilities such as an area library service organization (ALSO), a periodical center, a last copy retention center and a communications and delivery service. Specific recommendations for action are given. Further data on the MOLO libraries surveyed is appended. (Author/KE)
