The contents of this annotated bibliography are divided into six parts, prefaced by a general description of the conditions and problems of the Puerto Ricans on the United States mainland. Part I comprises a list of general bibliographies. Part II concerns "The island experience," and first lists general works and then specific works. Part III concerns "The migration to the mainland." Part IV concerns "The mainland experience," and first lists general studies and then studies specifically concerning conflict and acculturation. Part V focuses on "The mainland experience: education." In the first of three sections, it lists unpublished materials; then unpublished and published materials from the New York City Board of Education; and, finally, general studies. Part VI, "The mainland experience: the social context," first lists materials on "health, employment, and related social needs," and then on miscellaneous topics. (JM)
