Biographical material is slight. It includes, however, drafts for his autobiography and a bibliography, albeit incomplete. Research papers principally comprise 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. In addition there are a very small number of notes and drafts by Mott and others, 1989-1996. Only a small number of Mott's public and invitation lectures are documented, 1964, 1986-1994. 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.
There is documentation of Mott's association with eleven British and international societies and organisations. 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. There is a record of a small number of visits and conferences attended by Mott in the UK 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. There is useful documentation of 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 Kng, and drafts for Can scientists believe?, Mott's shorter publications and writings, and sermons. Finally, there is a chronological sequence of correspondence, 1968-1996, predominantly incoming, reflecting Mott's continuing interest in research to the end of his life. It includes correspondence and papers on energy questions, especially solar energy and photovoltaics, and high temperature superconductivity.
