The Lectures (1958-1988) series was labeled "trip files" by Coombs since it primarily dealt with lectures, symposia, and courses offered off of the University of Michigan campus. The few lectures given at the University of Michigan were presented outside Coombs' normal classroom setting. This series comprises just over one linear foot of materials and primarily consists of lecture notes and correspondence related to Coombs' latest research. Since Coombs was usually addressing a well-informed audience of his peers or graduate students, these materials detail the development of his thinking on theory of data, portfolio theory, unfolding technique, risk and decision making, family composition preference, and single peaked preference in the structure of conflict.
