A five year plan and budget for Pennsylvania library cooperative activities is outlined based on two goals: (1) libraries should support state educational, industrial, governmental, health and other information programs by joining in a statewide library network to provide all publicly available information in the state to any citizen; and (2) libraries should serve as the link between the user's information needs and the library and non-library world of information. Interviews with library consortia representatives and librarians, and review of plans in other states reveal the strength of existing cooperative programs upon which proposals for new management procedures are built. Principal recommendations are: (1) better methods of library service delivery between cooperating institutions--i.e., location of materials and administration of interlibrary loans; (2) more effective leadership emphasizing the central role of the State Library; and (3) evaluation methods for cooperative activities. Changes in legislation are proposed to enable any library in the State to obtain service from any state aided library. (Author/KP)
