An informal survey, conducted by the Colorado State Library, revealed few real efforts to serve the Spanish-surnamed beyond the minimal provision of Spanish language materials. To improve this situation, Colorado State College held a federally supported institute in June, 1969. Eight teams of participants were selected for the program, a team consisting of five members of one community: a trained professional librarian, a Spanish-surnamed library aide, a Spanish community leader, and two others of their choice. The goals of the institute were to increase librarians' understanding of the culture and needs of the Spanish-surnamed, through lectures and discussion with the participating community leaders, and to translate these needs into effective use of library materials. Each team developed such a plan for the library of their own community. Major efforts at evaluating the institute were concerned with the anonymous reports submitted on the last day by the participants. Most felt that the institute was successful in promoting understanding of cultural problems and differences. Verbatum copies of these reports are presented, as are the eight team plans for improved library service to the Spanish-surnamed. (SL)
