The collections span nearly a century, from the Mexican revolution period to the contemporary era. Some relate to US military intervention during the revolution. Others concern the history of Mexican radicalism, focusing on the Mexican Communist Party, various Mexican Trotskyist organizations, and the 1968 student protest movement. Several collections contain materials on modern art in Mexico in the first half of the twentieth century.
