This collection is composed primarily of correspondence, memoranda, course material, photographs, drawings and slides. The collection is broken down into personal and academic papers. The academic papers pertain mainly to Colquhoun's career as a writer and theoretician and professor at Princeton University's School of Architecture. The personal papers consist mainly of correspondences with friends and family, as well as notebooks, which Colquhoun kept from the 1940s. The visual materials (photographs and drawings) straddle the two categories. Many of the photographs were taken by Colquhoun himself, to be used later in his teaching, while the drawings consist of both student work and reproductions of works from his practice with John Miller. For the majority of the collection, Colquhoun's folder titles have been maintained and the material has been arranged chronologically. The collection is arranged into four series.
