The collection covers most aspects of Williams' life and career after 1939. Papers from her work with the British Colonial Service in Ghana, 1928-1936, were largely lost during transit to her next appointment in Singapore, but the typescript copy of her 1935 report The mortality and morbidity of the children of the Gold Coast is extant. Many papers relating to Williams' work with the British Colonial Service in Singapore, 1936-1941, were lost during the Japanese invasion, but she took a few files into Changi jail, where she wrote up the report An experiment in health work in Trengganu in 1940-1941. Notebooks, correspondence and writings made during her internment, when she was appointed as camp nutritionist by her fellow women prisoners, are also in the collection. Post-war papers cover most aspects of Williams' work, including positions with the World Health Organisation, the American University at Beirut and Tulane School of Public Health, as well as correspondence and collected reprints relating to work carried out in 'retirement' at Wyndham House, Oxford.

Some of these records are concerned with obstetrics and gynaecology during the period of the Second World War.
