The Research Subseries comprises Carrier's research materials on the sexual behaviors of Mexican men in Mexico and Latinos and Vietnamese in Southern California. They are arranged chronologically, from Carrier’s proposals, through his interview notes and completed respondent questionnaires, to his analysis of the collected data. The bulk of the series consists of Carrier’s original notes and research in Guadalajara in 1968-1971. Carrier maintained contact with several respondents, and correspondence with these individuals will be found in the Correspondence Series. The series also includes materials concerning the gay liberation organization in Guadalajara, Grupo de Orgullo Homosexual de Liberación (GOHL).
