Executive Order 721

Officers in the executive departments who have charge of archives or administrative records are instructed, in so far as public interests and departmental orders permit them to do so, to allow agents of the Department of Historical Research of the Carnegie Institution of Washington, bearing proper credentials from the Director of that Department, to have access to those papers, for historical purposes, at all times which are not inconvenient in respect to public business, and under such proper conditions as may be desired.
