The majority of the collection consists of official publications documenting a variety of facets of Perón's political career, including his involvement in the 1943-1946 military government, his first two presidential terms (1946-1955) and his third (1973-1974). Most of these official publications are reports on his policies and political activities, his own writings, or transcripts of speeches. Several of these record conjoined efforts by Perón and Eva, his well-known first wife, as well as with Chilean president Carlos Ibáñez Del Campo.
Also contained in the collection are pamphlets and other materials which treat Peronism (or Justicialism) and its critics; two series of satirical pro-Peronist periodicals called "Alpargatas Humorísticas" (6 issues) and "Descamisada" (31 issues); 8 postcards which depict aspects of Eva Perón's social work; two paper masks of Juan Domingo Perón and Eva Perón; two autographed photographs of Juan Domingo Perón and Eva Perón; and other ephemera.
The Nicaragua collection documents the Nicaraguan diaspora living in Miami during the 1980s and the political and social conditions in Nicaragua from the 1979 Sandinista revolution onward until their loss of power in 1990.
Many of the materials falling into the latter category are from the United States in origin, such as anti-Soviet propaganda endorsing the anti-Sandinista "Contra" Freedom Fighters, pamphlets that describe the Sandinista government and Central America in general from an American perspective, and periodicals and reports about Nicaragua written to an American audience. The materials that document the Nicaraguan diaspora are mostly fliers, menus, calendars, brochures, and other genres that were from local Nicaraguan businesses, restaurants, clubs, and other organizations. Some of the materials transcend these two categories, as many that concern the political conditions are addressed to or produced by Nicaraguan exiles.
A large part of the collection consists of photocopies of news articles.
Writers that are especially represented by the collection include Ruben Dario, Esteban Duque-Estrada, and Luis Mejia Gonzalez. Associations and organizations that are especially represented include Alanzia Revolucionaria Democrática (ARDE), American Defense Foundation, American Defense Lobby. Asociación Nicaragüenses en el Exilio, Asociación Nicaragüense pro Derechos Humanos, Bloque Opositor del Sur (B.O.S.), Council for Interamerican Security, Fundación Ruben Dario, Nicaraguan American Solidarity (NICAS), Nicaraguan Freedom Fighters, Partido Conservador de Nicaragua, Partido Socialcristiano de Nicaragua en el Exilio, Resistencia Nicaragüense, and Unidad Nicaragüense Opositora (UNO). Materials from some of these were grouped together in a series titled "Associations."
Also of notice are brochures advertising tourism to Nicaragua during the Sandinista regime, and memorabilia such as a handmade Nicaraguan crest, Nicaraguan paper money from the Sandinista era, and a pin that says "If you like Cuba you'll love Nicaragua."
