A Articles, speeches and writings A.1-A.16
B Notes, drafts and working papers B.1-B.10
C Committees, conferences, organisations C.1-C.12
D Scientific correspondence D.1-D.3
With few exceptions (A.1, A.2, B.2, B.3) nothing survives of Rideal's early scientific career, and very little of his long and extensive involvement in scientific committees and societies.
Most of the speeches and writings in Section A. belong to the last years of Rideal's life (1970-73); several of them are of interest in containing reminiscences of his career and of the development of colloid and surface sciences. The scientific notes and working papers in Section B. similarly belong in the main to a later period (see the introductory note to Section B), as does the small amount of surviving correspondence in Section D.
All correspondents are listed in the Index.
