The papers in this section were found in Needham's folders. The material was principally used by Needham for updating his lectures on biochemistry to postgraduates. The folders bore Needham's inscriptions listing the subjects covered by the material in the folders and usually an abbreviation referring to the course for which the material was pertinent. The abbreviations 'CB', 'CP' and 'CPB' refer to courses in comparative biochemistry, 'CE' or similar refers to a course in Chemical Embryology, 'IRA' to biochemical aspects of Integration, Regulation and Adaptation, and 'CE/IRA' to a combined course in the two given in the mid-1960s. These folders were in some cases also numbered. Some of the material was used in more than one course. A number of folders are very heavily inscribed and therefore have themselves also been preserved. Some of the material was also used by Needham in the preparation of his 1955 review article in the Annual Review of Physiology 17 (see GBR/0012/MS Needham F.353, GBR/0012/MS Needham F.354) - many folders bear the inscription 'ARP 54/55' or similar. The material is chiefly bibliographical references, notes on the literature and offprints. Many of the offprints have been annotated by Needham, some extensively, and some offprints have manuscript notes intercalated. The bulk of the material dates from the 1950s and 1960s although there is older material in some of the folders. There are also syllabuses and instructions for practical work. The catalogue entries give the abbreviation (where possible) and the main titles found on the folders. GBR/0012/MS Needham B.42- GBR/0012/MS Needham B.116 Comparative Biochemistry GBR/0012/MS Needham B.117- GBR/0012/MS Needham B.145 Chemical Embryology GBR/0012/MS Needham B.146- GBR/0012/MS Needham B.174 (Biochemical aspects of) Integration, Regulation and Adaptation GBR/0012/MS Needham B.175- GBR/0012/MS Needham B.193 Chemical Embryology/Integration, Regulation and Adaptation GBR/0012/MS Needham B.194- GBR/0012/MS Needham B.229 Other folders GBR/0012/MS Needham B.230 Crystallography
