These papers are largely concerned with Humphreys' involvement in the development and promotion of Latin American Studies in Britain. The collection is roughly divided into three series. The 'correspondence' section includes letters from a variety of people, including British historians such as Hugh Hale Bellot and historians of Latin America and the USA (1934 to 1982). Amongst the papers of committees and conferences promoting Latin American Studies in Great Britain in the second section are: papers of the University College London Advisory Committee and the University Grants Committee on Latin American Studies; correspondence relating to committees; interview papers and reports. The third section contains items created by Professor Humphreys including unpublished papers, and printed newspaper articles.
