This catalog provides ideas for sharing library resources, programs, administrative and other procedures, and services between all sizes of public libraries in Vermont. It is noted that many of the ideas are the result of a 1981 survey of Vermont public librarians, and their perceptions of library needs and additional desired services, as determined by the survey, are briefly outlined. Also included are a description of cooperative efforts organized by the Vermont Department of Libraries (DOL), an outline of suggested first steps in library cooperation, an overview of semi-formal and formal cooperative arrangements, a listing of the advantages and disadvantages of library cooperation, and a brief discussion of essential ingredients for successful cooperation--effective people, effective use of geography, and effective self-appraisal. Appendices include a chart outlining types of materials and services that can be borrowed from seven types of libraries; information on the members, history, operations, problems, and successes of existing library cooperatives in Vermont; a map showing Vermont's public and community libraries; and a questionnaire which can be used to send additional information on library cooperative activities to the DOL. An index to the cooperative ideas presented is provided. (ESR)
