Thirty rural libraries in Colorado, Kansas, and Oklahoma have been selected to participate in a 1-year project to assist public librarians in implementing humanities programming for adults; "Heritage of the Plains and Mountains" is one of three packets compiled for the project. The packet is designed to provide a step-by-step guide for the librarian with little or no experience in adult programming. Following a list of the participating libraries, the packet includes an overview of the heritage of rural mid-America and provides two suggested program formats. Resource people from Colorado, Kansas, and Oklahoma are listed, as well as state and national resources. A bibliography of the heritage of the plains and mountains lists 20 references for Colorado, 21 for Kansas, 20 for Oklahoma, and 42 works about the heritage of the region. A filmography lists 24 films (16mm) and other film information. Lists of free and inexpensive materials and miscellaneous resources precede a 25-page adaptation of "Planning Library Programs" by Peggy O'Donnell and Patsy Reed. (BRR)
