Included is correspondence between the Chief of Specialized Agencies and ACC Affairs, the Secretary of the ACC, and the Special Representative in Europe for Coordination and ACC Affairs. These were secondary positions held by UN Secretariat staff. The correspondence covers common interests of the specialized agencies, such as family planning, oceanography, atomic energy, and the peaceful uses of outer space. It also discusses relationships with non-UN intergovernmental agencies (IGOs), the role of the ACC, whether the specialized agencies should use individual flags or the UN flag, and the biological aspects of race.
