The papers consist mainly of historical information on USSALEP, minutes, correspondence, records of the various projects and individual files on management committee members and some exchangees. Not all files have been retained; in the case of fundraising correspondence and individual files a sample was considered sufficient to indicate the scope of the project for historical purposes. There is a certain amount of duplication; for the convenience of researchers the minutes have been collected separately in D and additional copies may be found in the correspondence files and mailings to members; material of historical interest may also be found in correspondence files, which are a rich source of information on the organisation. Some photographs are in the original personal files and some have been assembled under N. A number of photos are not identified.

The collection contains trial records relating to Wouter Basson, the former head of the South African Apartheid state's Chemical and Biological Weapons Programme (CBW), covering the years 2000-2003.
