The American Civil Liberties Union (ACLU) is the pre-eminent civil liberties organization in the United States, utilizing litigation, lobbying, and public education to defend and preserve the individual rights and liberties guaranteed by the U.S. Constitution. These records document the administration and work of the ACLU's national office, regional offices, and legal projects, with particular emphasis on the areas of civil rights, children and women's rights, freedom of speech (and all First Amendment questions), and due process, among many others. The records include case files, correspondence, meeting minutes, research files, and files of staff members. Portions of the records (Subgroup 1; Subgroup 2, Series 2, 3, and 4; Subgroup 3, Subseries 5B) have been digitized and are available for members of the Princeton community to view here .
