Abstract: | Most of the literature on the participation of public libraries in cooperative activities deals with their expansion from local entities to multitype system. Within the framework of this evolution, topics of special interest have been: (1) appropriate units of senrice; (2) legal and political considerations; (3) stimulus of legislation; (4) role of states and state library agencies; (5) financial aspects; (6) human factors; and (7) automation in networking. The literature reviewed was vast but was deficient in comprehensive syntheses, in rigorous, large-scale evaluations of networking, and in studies focusing solely on public libraries. |
