Smith lived to a great age, and was prolific in writing and research to the end of a life devoted to his chosen field of plant and insect viruses.
The surviving material offers only a partial picture of his career. Little personal or biographical material remains, though it is not generally known that in 1947 he was offered the post of Head of the Mycology Division at the Indian Agricultural Research Institute, New Delhi (see CSAC 91.2.83/A.3). Smith's own research is quite well documented in Section B, and his research reports, plans and annual schemes of work at different dates are of interest (see CSAC 91.2.83/B.5, CSAC 91.2.83/B.8, CSAC 91.2.83/B.23, CSAC 91.2.83/B.28). He is known to have organised many exhibitions, but the only record of these are the correspondence at CSAC 91.2.83/E.3, CSAC 91.2.83/E.4, and some sample captions at CSAC 91.2.83/B.29.
Smith wrote many books, several of which became standard textbooks regularly reprinted or updated for new editions. Samples (only) of this activity, including the continuing work of his seventies and eighties and also his own scrapbook of reviews, are at CSAC 91.2.83/C.1 - CSAC 91.2.83/C.13. The shorter articles and reviews at CSAC 91.2.83/C.14 - CSAC 91.2.83/C.72 are all additional to the technical papers listed in the Bibliography of the Memoir and give an idea of the extensive writing load Smith undertook for a more general readership.
Very few lectures, conference papers or broadcast scripts remain, and are preserved in Section D. The surviving correspondence in Section E is also disappointingly sparse.
