This series consists of notes, outlines, syllabi, schedules, and other materials related to Ruth Barcan Marcus' teaching career. The bulk of these materials were produced during Marcus' tenure as a professor at Yale, though the dates of some files correspond to her academic appointments at the University of Illinois at Chicago and Northwestern University, respectively. Many of the materials are identified by the specific course taught, while others are identified by topic with no indication of the course for which documents were used.
