The materials in this file may have been used to support the creation of the article titled, "The data transform programming method and file processing problems"by C.J. Lucena, R.C.B. Martins, and P.A.S. Veloso (Departamento de Informática, Pontifícia Universidade Católica, Rio de Janeiro, Brazil) and Donald Cowan (Department of Computer Science, University of Waterloo).

Material related to a proposal with the Canadian International Development Agency to support a twinning agreement between the Computer Science Department of the Pontifical Catholic University (PUC) of Rio de Janeiro, Brazil and the Computer Science Departments of the Universities of Waterloo and Toronto. Includes correspondence, draft copies of the proposal with notes and corrections, notes, two copies of a report titled, "The application of computer technology for development: report of the Secretary-General" published by the United Nations Economic and Social Council on May 20, 1970, and related items.

Accrual consists of materials created and accumulated by Alice Riggs Hunt and her family. Includes correspondence to and from Alice, locks of hair, and photographs. The photographs document other members of the Hunt family including her mother Mary Osgood Riggs Hunt (1860-1953) and her brother Charles Warren Hunt Jr. (1888-1953). Also present are over 500 slides documenting Charles Warren Hunt Jr.'s trip around the world.
