The collection consists of ten notebooks kept by William C. Seitz as a graduate student in the Department of Art and Archaeology at Princeton University. Notebooks include reading and lecture notes, sketches of ancient sculptures and buildings, test booklets, course syllabi, and assignments for his early courses on ancient art and architecture in 1949 and 1950. They contain both typescript and manuscript notes, chronologies, and outlines, including frequent annotations, drawings, and clippings from art history textbooks. Notebooks also contain notes and reflections on lectures by Princeton professors including E. Baldwin Smith and Richard Stillwell.
