The Antonio Arias Papers consists of circular letters, proclamations, statements, press releases, and other correspondence sent to Antonio Arias during the 1960s and 1970s by Cuban exile organizations. Some of these groups were paramilitary organizations engaged in subversive activities, such as Comandos Omega 7 and Joven Cuba Nacionalista. The collection also includes a copy of "Acta final de los diálogos celebrados entre el gobierno de la República de Cuba y personalidades representativas de la comunidad cubana en el exterior - los días 20 y 21 de noviembre y 8 de diciembre de 1978."

These materials were received and collected by Antonio "Cuco" Arias while a radio journalist at WFAB La Fabulosa, a Spanish-language radio station in Miami, Florida. Mr. Arias worked at various radio stations and went on to serve as an executive producer for television with Univisión, the Spanish-language media company.
