44 U.S.C. § 1503

The original document required or authorized to be published by section 1505 shall be filed with the Office of the Federal Register for publication at times established by the Administrative Committee of the Federal Register by regulation. The Archivist of the United States shall cause to be noted on the original of each document the day and hour of filing. Upon filing, the document shall be immediately available for public inspection. The original shall be retained by the National Archives and Records Administration and shall be available for inspection under regulations prescribed by the Archivist, unless such original is disposed of in accordance with disposal schedules submitted by the Administrative Committee and authorized by the Archivist pursuant to regulations issued under chapter 33; however, originals of proclamations of the President and Executive orders shall be permanently retained by the Administration as part of the National Archives of the United States. The Office shall transmit to the Government Publishing Office, as provided by this chapter, each document required or authorized to be published by section 1505. Every Federal agency shall cause to be transmitted for filing the original of all such documents issued, prescribed, or promulgated by the agency.
