Much has happened in the field to alter the nature of library services to the Mexican American. The newest areas of library services available to Mexican Americans are at the public school and at the university level. This paper brings together some new concepts, trends, and feelings in the areas of library services in general, and in public, school, and university library services for Mexican Americans. Topics discussed are: a systematic review and analysis of library services for the Spanish speaking; concepts of information services in a Chicano context; library services to Mexican Americans in Texas (a statement presented before the U.S. Commission on Libraries and Information Science); the national concern of library services to the Spanish speaking (testimony presented to the National Commission on Libraries and Information Science); library reform sought by REFORMA, a bilingual librarians' group; public library boards, the Chicano and the political process; a model for public library services in the Mexican American community; some problems and recommendations about the impact of bilingual education on school library services; the integration of library skills instruction with the bilingual/bicultural program; Chicano periodicals as classroom resources; an overview of Chicano libraries, special collections, and projects currently in existence; the Mexican American Library Project, a model for university service to the Spanish-speaking people. A 51-item bibliography of library related and non-library related sources is appended. (NQ)
