The American Civil Liberties Union Records document the activities of the Union in protecting individual rights from 1920 through 1995. The files contain materials on freedom of speech, expression, and association; due process of law; equality before the law; legal case files; and organizational records. Within these categories files reflect subject areas such as academic freedom, censorship, racial discrimination, aliens' rights, privacy concerns, labor concerns, amnesty, and government loyalty and security. The files reflect work on litigation, advocacy and public policy, and subject files on various areas of interest connected with civil liberties. Materials include correspondence, court documents, memoranda, printed matter, minutes, reports, briefs, and legal files. Also included are materials from ACLU affiliate organizations, and the Lawyers Constitutional Defense Committee.
