Consists of records documenting incoming and outgoing correspondence and administrative files maintained by Assistant Directors Kenneth H. Drummond (1959-1961) and Carlton W. Tillinghast (1961-1969) and when his position was known as the Assistant Director (Managment). Records prior to 1959 were created mostly by Executive Officer, Vaughan Harmon.

The records primarily concern SAO administration and scientific projects, including the Celescope Project; Radio Meteor Project; SAO-International Year of the Quiet Sun Comet Project; Prairie Network (Meteorite Photography and Recovery Project); and the Satellite Tracking Program. Of special interest is correspondence regarding the closing of the Table Mountain (California) station in 1961.
