Solly Zuckerman played a major role in drafting the Group's report and in strengthening the language used in it. This is reflected in the size of File SZ/UNPO/5, which includes the drafts of the report and Zuckerman's notes made during its preparation.
File SZ/UNPO/1 includes a small album of photographs of members of the Expert Group taken during its programme of meetings in Geneva, August-September 1971.
File SZ/UNPO/2 consists chiefly of the contents of one of Zuckerman's personal files as Chief Scientific Adviser (old file reference Z/76/3), transferred to his office at UEA following his retirement and to which related material already held at UEA was added at that time.
File SZ/UNPO/3 includes lists of members of the Expert Group; photocopied extracts from various publications; Disarmament. Twenty-five years of Effort, by William Epstein, Canadian Institute of International Affairs, 1971; Address to the Board of Governors by Robert S. McNamara, President, World Bank, Copenhagen... September 21, 1970, Washington DC, International Bank for Reconstruction and Development, ; Economic and Social Consequences of Disarmament. Report of the Secretary-General transmitting the Study of his Consultative Group, New York, UN Department of Social and Economic Affairs, 1962; Preliminary report [of the] Herbicide Assessment Commission of the American Association for the Advancement of Science, 30 December 1970. The last is a loose-leaf publication with photographic illustrations dealing with the military use of chemical herbicides in South Vietnam.
