The Arts Censorship Project series is largely composed of case files, resource files, and publicity about the project. In the cases, the ACLU frequently combated the censoring of artistic expression and the media, removing art from exhibits for being offensive, and censoring pornography through obscenity laws. The resource files, which are copies of publications, include significant material on copyright, music censorship, nudity, pornography, privacy, religion, schools, speech, state laws, and television. Project newsletters and newspaper clippings make up the publicity files. The remaining materials document the administration of the project and include correspondence, sample forms, research memos, and financial records.

The Capital Punishment Project subseries documents the ACLU's opposition to the death penalty and includes files on state legislation, clemency policies, and subject files on the wide range of issues involved, such as research and statistics on the application of the death penalty, death penalty cases, organizations with similar goals, the court system, and capital punishment internationally. The records also document the administration of the project, including the files of director Henry Schwarzschild, files from affiliate involvement with the project, project publicity, correspondence, and publications.

The majority of the Children's Rights Project subseries is composed of case files. The best documented cases relate to foster care reform and include Del A. v. Edwards , Smith v.

Miller regarding Georgia's congressional districts. The correspondence includes letters from prisoners with general appeals for ACLU help on due process violations and project correspondence with the Southern Regional Office and with affiliates. Also included are files on organizations involved in related advocacy work, publications, speeches, and newspaper clippings.

The majority of the Women's Rights Project subseries is composed of case files. Well documented cases challenge sexual discrimination and include Christman v.
