On March 31, 1978, over 70 administrators of libraries, library staff members, and network representatives from all types and sizes of libraries in all areas of Wisconsin participated in a workshop to investigate alternative structures for providing interlibrary loan and reference referral services at the state and area levels. These proceedings from the workshop present the texts of the four speakers' addresses on the definition of resource sharing, resource sharing and new technology, state-level library resource development, and alternative patterns for resource sharing (unstructured, clearinghouse, multiple resource center). Also included is a description of the small group discussions session that considered the ideal patterns for each of nine geographical areas of the state. Summaries of those discussions are presented in tables that list the disadvantages and advantages of each pattern by the number of groups citing them. Appendices provide the workshop agenda, workshop goal and objectives, a list of workshop participants, and summaries of small group discussions by geographical area. (JD)
