The Office of the Federal Register (OFR) of the National Archives and Records Administration(NARA), and the U.S. Government Publishing Office (GPO) jointly administer the FederalRegister.gov website. We developed this website to make it easier for citizens and communities to understand the regulatory process and to participate in Government decision-making.
