Publications is extensive but chiefly relates to Needham's pre-war and wartime publications. Included in the section are not only drafts of many of his scientific papers and books but also writings on philosophical, religious and political themes. A number of his more scientific works are particularly well-documented. These include his philosophical monograph Man a Machine (1927) and his two most significant biochemistry books Chemical Embryology (1931) and Biochemistry and Morphogenesis (1942). Among Needham's political writings represented are his article 'Laud, the Levellers and the Virtuosi', published in Christianity and the social revolution (1935), and The Levellers and the English revolution (1939), which was published under the name 'Henry Holorenshaw'. There is also good documentation of the books The sceptical biologist, (1929), The Nazi Attack on International Science (1941), Science in Soviet Russia (1942), and his two final collections of articles Time the refreshing river and History is on our side, published in 1943 and 1946 respectively. Needham's later publications represented include his paper 'History and Human Values: a Chinese perspective for world science and technology', published in the Centennial Review and subsequently in The radicalisation of science. Ideology of/in the natural sciences (1976) edited by S.P.R. and H. Rose. The section also includes a number of Needham's translations of Polish and Chinese texts, including Green Thraldom by Tang Pei-Sung (1949), extensive editorial correspondence, including requests to write articles or books, and an incomplete set of Needham's offprints.
