Executive orders are directives issued by the president to agencies or other government officials. Presidential proclamations are policy statements issued by the president to the public. Although proclamations are often ceremonial, they can have legal effect (especially when regarding national emergencies, foreign policy, and federal land management). The official publication of both these document types is the Federal Register.
