The manual was compiled by participants of an institute designed to train librarians to work with American Indians and Mexican Americans. Information is provided to aid library personnel in understanding the cultural backgrounds of these minority groups. Criteria for selecting books for and about Mexican Americans and Indians are included, as well as reader's interest and library-interest forms. Criteria for judging library services to rural and small communities are also given. Implementation of library services is discussed in terms of the library, the student-librarian relationship, the total school, the community, and state and national activities. Lists of bibliographies on Indians, Mexican Americans, and both Indians and Mexican Americans are included, and each entry is coded for interest and use level. Supplementary reading materials for cultural enrichment are listed for both Mexican Americans and Indians, and these are also coded by interest level. Resource materials such as films, records, magazines, and newspapers are cited, and a directory of sources concludes the document. (LS)
