The fonds is composed of correspondence; course material; drafts of articles, books and other works; financial and judicial records, such as benefits statements or contracts; material written for public addresses, such as speeches or notes; photographs of Mr Watson; and a short section focusing its attention on the various appointments he had. This fonds is particularly interesting for the shear amount of course material that one can find here. Indeed, it composes a good third of the entire volume of this fonds and spans 20 courses over 40 years of teaching.

While attempting to give a complete look at William Watson’s life, the fonds is distributed into the following 5 series:
A. Biographical records
B. Professional records
C. Distinctions
D. Correspondence
E. Graphical material
