The papers are extensive but by no means comprehensive. There is no personal or biographical material and very little record of Thompson's research.

There is a very full record of Thompson's Foreign Secretaryship of the Royal Society and his organisation of the European chemical conferences (EUCHEM) and substantial documentation of his work for ICSU and IUPAC, including the Commission on Molecular Spectroscopy and the Triple Commission on Spectroscopy. Thompson's contributions to international relations were not limited to science (or football) and he kept detailed records of his Chairmanship from 1972 of the Great Britain - China Committee (later Great Britain - China Centre). The football papers are substantial, particularly for the last decade of Thompson's life, and thus there is full documentation of his Chairmanship of the Football Association and of the many problems facing football at that time, including hooliganism amongst its supporters.
