This series contains photographic prints, slides, negatives, and other graphic materials on individual countries in Latin America on subjects such as agriculture, economics and industry, guerrilla actions, human rights, indigenous peoples, labor policy, military actions, political demonstrations, religious issues, and women's rights. Prominent events appearing in this series include Fidel Castro's 1959 Cuban Revolution, the Sandinista movement in Nicaragua and the activities of the FSLN (Frente Sandinista de Liberación Nacional, Sandinista National Liberation Front); and the 1954 Guatamalan coup. A small amount of materials document protests and demonstrations in France, the Middle East, Asia, and the United States. Although the materials in this series date from the 1940s through the 2000s, the majority of the materials are dated from the 1960s through the 1990s.

This series consists of publications both created and collected by NACLA. Publications created by NACLA include one-off publications that are not part of an ongoing series, compilations of articles written by NACLA staff sent to news services, and its regularly published journal, known by the following names throughout the years: the NACLA Newsletter (1966-1971), NACLA's Latin America and Empire Report (1971-1977), and NACLA Report on the Americas (1977-1991). Publications collected by NACLA include research materials such as general political guides and bibliographic information for human rights organizations.

This series contains files collected by NACLA that the organization referred to as "NACLA in the News," mostly from the 1980s and 1990s. Materials include newspaper clippings, press releases, and copies of articles on media consultation, staff writings outside of the organization, and opinion pieces on NACLA activities, including both praise and criticism from the left and right. This series also includes George Black's 1984 op-ed from The New York Times and the various reactions to it, illustrating an ideological rift in NACLA concerning the Reagan administration's involvement in the 1984 Nicaraguan general election under the Sandinista Directorate.
