This bibliography is part of a study of cooperation among local governments in rural areas. Information about materials on this topic has not previously been readily available. Because agricultural areas may benefit from experience with interlocal cooperation in urban areas, the bibliography includes materials reporting such experience. Thus, it also serves as a source of information for those concerned with problems of general local government. The term intergovernmental relations has been employed so often to refer to the relations of the Federal, State, and local governments that the term has come to mean the vertical flow of influences among these governments. Our interest is limited to the relationship among local governments, and of a special kind--interlocal governmental cooperation.
