The correspondence files are chiefly photocopies of letters and comments from the international committee, letters and memoranda of Jackson's staff and letters from Dubos to Jackson. There is one cataloged letter from Hubert H. Humphrey. The manuscript consists of numerous versions with corrections by the authors, the final edited manuscript for the publisher and printer and page proofs. Also, files relating to publicity, serial rights, and reviews for the book. In addition, there is an audio tape package (4 cassettes) entitled "The International Development Strategy: an In-depth Discussion" (Schloat Productions, 1973). A number of the panel members were Columbia University faculty members.
