Smithsonian Astrophysical Observatory. Assistant Director (Management)

Around 1964, a numerical-subject records management system was instituted at SAO. Records were assigned a number code based on subject classification and filed numerically. Often records prior to 1964 were refiled using the numerical-subject system. Retrieval of records using the system is difficult.

Prior to 1959 the duties of this office were performed by the Executive Officer, Vaughan Harmon. For an administrative history of the Office of the Assistant Director (Management), see record unit 256.
