Congressional documents concern a wide variety of subjects and include all papers ordered printed by the House or Senate apart from congressional committee reports. As described by the Government Publishing Office (GPO), congressional documents “may include reports of executive departments and independent organizations, reports of special investigations made for Congress, and annual reports of non-governmental organizations.” Researchers also frequently ask us for assistance in finding Senate treaty documents, which contain the “the text of a Treaty as it is submitted to the U.S. Senate for ratification by the President of the United States.” House and Senate document citations include the number of the Congress and the number of the document. For example, "S.Doc. 114-15" indicates the fifteenth document from the 114th Congress, while "Treaty Doc. 114-1" indicates the first treaty document in the 114th Congress.
