The collection comprises subject or case files compiled by Professor Edgeworth Johnstone during his research and professional practice. It is probable that the surviving files were compiled during his time as Professor of Chemical Engineering at the University of Nottingham, since the datable material covers the period 1960 to 1967. The files contain manuscript notes, correspondence and associated papers accumulated during this period. The files can generally be classified into three groups:
- The first and largest group consists of files relating to scientific research, including industrial chemical processes, compounds, pollution, 'scale-up', safety, research, development, education and patents.
- The second group of files primarily concerns methodological matters, including technical filing systems, 'work study', management, statistics, cost estimation and report writing.
- One file holds personal papers, concerning Edgeworth Johnstone's interest in sailing.
Lectures, reports and articles written by Edgeworth Johnstone include the titles: 'The transference of chemical processes from small to large scale operation' (1939); 'Potential markets for high-volatility petroleum coke in Brazil' for Trinidad Leaseholds Ltd (1937); 'Continuing education for engineers' (Helsinki, 1972); 'The future of pilot plants' (c.1961); 'Second survey of chemical engineering and practice' presented to the Institution of Chemical Engineers (1965); 'Scale effects in chemical plants' presented to the students and graduates section of the Institution of Chemical Engineers (1965); and 'Some thoughts on engineering education', given as his inaugural lecture as Lady Trent Professor of Chemical Engineering at the University of Nottingham (1962).
