Archives Unbound presents topically-focused digital collections of historical documents that support the research and study needs of scholars, researchers, and students at the college and university level. A multi-disciplinary resource, collections cover a broad range of topics from the Middle Ages forward-from Witchcraft to World War II to twentieth-century political history. Particular strengths include U.S. foreign policy; U.S. civil rights; global affairs and colonial studies; and modern history. Collections are chosen based on requests from scholars, archivists, and students.

Archives Unbound: Law, Politics, and Radical Studies contains the political and legal history of the United States as highlighted in the papers of politicians and the organizations that supported them, and documentation from the Federal Bureau of Investigation and Justice Department.  These collections also feature materials about world communism and the evolution of the American militia movement.
