The EFD program was phased out in 1978, with future university grants made within the appropriate RF program areas. Retaining the files' original order preserves the usefulness of numerous cross-reference inserts which refer to related files by number. While the focus of the Bogota office was agriculture, the Cali office coordinated programs in rural, community, and university development. Series IV includes correspondence between the Cali staff and several American universities cooperating with the Universidad del Valle in rural and tropical disease research, preventitive medicine and nutrition, and child and public health. Correspondents include Farzam Arbab, Ulysses J. Grant, Guy S. Hayes, Robert S. Morison, Patrick N. Owens, Dorothy Parker, Virgil C. Scott, Harold Trapido, John Veenstra, and John M. Weir.
Some correspondence is in Spanish.
