Each type of document has its own numbering scheme. Executive orders and proclamations have been issued since 1789. The older executive orders were not numbered and there exists a separate series of these unnumbered executive orders. They relate to the conduct of government business or to the organization of executive agencies. Authority for executive orders is derived from the nature of the President's office, his role as commander in chief of the armed forces, from the Constitution, and from existing legislation.
Proclamations are general announcements of policy addressed to the entire nation.
Directives Directives are used to designate matters, such as assignments for officials of agencies. Presidential Determinations Presidential determinations resolve that certain provisions of law are or are not in the national interest. Reorganization Plans Reorganization plans consist of presidential proposals for changes in the form of agencies, and can abolish or transfer agency functions. A reorganization plan must now be approved by both houses of Congress before it can take effect. Reorganization plans are identified by year and plan number within that year.
