United States presidents issue executive orders to help officers and agencies of the executive branch manage the operations within the federal government itself. Presidential memoranda are closely related, and like executive orders have the force of law on the Executive Branch, but are generally considered less prestigious. Presidential memoranda do not have an established process for issuance or publication; unlike executive orders, they are not numbered. A Presidential determination is a determination resulting in an official policy or position of the executive branch of the United States government. A Presidential proclamation is a statement issued by a president on a matter of public policy. They are generally defined as, "the act of causing some state matters to be published or made generally known. A written or printed document in which are contained such matters, issued by proper authority; as the president's proclamation, the governor's, the mayor's proclamation."
Executive orders, Presidential memoranda, Presidential determinations, and Presidential proclamations are compiled by the Office of the Federal Register (within the National Archives and Records Administration) and are printed by the Government Printing Office. They are published daily, except on federal holidays. A free source of these documents is the Federal Register, which contains government agency rules, proposed rules, and public notices. There are no copyright restrictions on the Federal Register; as a work of the U.S. government, it is in the public domain.
