Section A, Biographical, is slight. It includes, however, drafts for his autobiography and a bibliography, albeit incomplete.
Section B, Research, principally comprises a sequence of published papers, pre-prints etc by other scientists annotated by Mott or occasionally by collaborators such as A.S. Alexandrov, 1946-1996 (bulk 1983-1996). In addition there are a very small number of notes and drafts by Mott and others, 1989-1996.
Section C, Lectures and publications, is the largest in the collection. Only a small number of Mott's public and invitation lectures are documented, 1964, 1986-1994 but there is a major sequence of drafts for his scientific publications, 1961-1996 which is especially substantial for his last years, though not always straightforward in its interpretation. Publications correspondence is not extensive and his long association with Taylor & Francis is represented by a relatively few papers, 1980-1996. There is a substantial but incomplete set of Mott's off-prints, 1929-1995.
Section D, Societies and organisations, documents Mott's association with eleven British and international bodies. His interests in nuclear weapons issues and defence questions more widely are reflected in the papers of the Oxford Research Group and the Pugwash Conferences on Science and World Affairs. Although Mott was a Fellow of the Royal Society from 1936 the record presented here covers the period 1976-1993 only, and relates almost entirely to his interests in science education.
Section E, Visits and conferences, documents a small number of such occasions attended by Mott in the United Kingdom and overseas for about twenty years from 1977 including invitations for 1996 and 1997 he was not able to fulfil. In addition to visits and conferences associated with Mott's scientific research there are records of a seminar on 'gifted' children at Cambridge, 1981 and the Second Nova Spes Colloquium of Nobel Prizewinners in Rome, November 1987 when Mott met the Pope.
Section F, Religion, documents Mott's developing interest in religion in his later years. There is correspondence, 1977-1996, including a small group of papers kept separately by Mott about the Swiss Catholic theologian Hans Küng, and drafts for Can scientists believe?, Mott's shorter publications and writings, and sermons. Section G, Correspondence, presents a chronological sequence of correspondence, 1968-1996, reflecting Mott's continuing interest in research to the end of his life. It also includes correspondence and papers on energy questions, especially solar energy and photovoltaics. The sequence is predominantly incoming. There is also an index of correspondents.
