Committee hearings are transcriptions of congressional committee hearings.
Committee prints, on the other hand, consist of a mixture of different types of congressional documentation. The content of committee prints vary depending on the needs of the committee and can include statistical materials, maps, analysis, and study results as well as other content types. Hearings and prints are not required to be published by law and have an irregular publication schedule, as they are released at the discretion of their authoring committees. The National Archives does, however, keep copies of congressional hearings.
Committee reports detail the committee findings regarding proposed legislation. These reports will document committee investigations as well as opinions regarding the proposed legislation.
Prints, Reports, and Congressional Documents are all included in the Congressional Serial Set. Prints, Reports, and Documents published after 1995 are freely available online through FDSys.
