There is some material relating to major policy decisions of the Council. There are also letters and reports from scientists involved in medical research and from Council staff members and representatives involved in family planning activities abroad.

This series contains Nelson A. Rockefeller's correspondence with private individuals and representatives of institutions and governments in 87 foreign countries. With some exceptions, this material consists mainly of financial appeals from individuals and institutions. Appeals from individuals include requests for money for such things as starting a business, traveling to the United States, or publishing a book. The range of institutions includes churches, universities, health centers, and businesses. Because Mr. Rockefeller followed his family's philanthropic tradition of aiding people through institutions rather than individually, nearly all of the personal appeals were declined. Only those institutional appeals that fell within Mr. Rockefeller's areas of interest were favorably answered. Most of the declination letters were written by members of Mr. Rockefeller's staff on his behalf.
