The papers of William Price, chiefly relating to spectroscopic analysis and photoionisation, comprise correspondence, lecture and teaching notes, notes compiled while reviewing scientific articles, original research notes, papers concerning Price's employment as an examiner, obituaries and reprints of journal articles, 1929-1993. These notably include correspondence with colleagues describing projects and experiments and sharing observations and data, 1942-1990; lecture notes and teaching papers compiled by Price on the theory of spectroscopy, theoretical and applied optics, especially microscopy, basic molecular chemistry, electron configurations and bond and dissociation energies of molecules, 1948-1978; notes compiled by Price for the peer review of articles and on Price's own published articles, including on the spectra of halogens, the structure of polyatomic molecules, on water and hydrides, the calculation of ionisation potentials, benzenes and hydrocarbons, the structure of the DNA molecule and natural fibres such as keratin, 1929-1977; original research notes on spectroscopic analysis, especially ultraviolet spectra of rare gases, ethylene, sulphur dioxide and other compounds, 1933-1986; papers relating to Price's work as an examiner including draft and complete examination question papers and correspondence, 1952-1978; papers concerning the membership by Price of various learned societies and attendance at scientific conferences and symposia, 1940-1992; obituaries and newspaper cuttings on Price and other distinguished scientists, 1976-1993; typescript copies and reprints of scientific journals containing articles by Price and others, on topics including spectroscopy, photoionization, ionisation potentials and electron configuration and bond and dissociation energies, 1945-1990.

The papers are extensive but by no means comprehensive. There is no personal or biographical material and very little record of Thompson's research. On the other hand his contributions to international science and football are extensively documented. 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.
