The Lansburgh collection is organized in two series: Personal Papers, including student work and travel diaries, and Project Records, which include drawings and photographs. Project records, which form the bulk of the collection, include extensive documentation of the design and construction of theaters. The collection, including his library of 118 volumes, was donated by Lansburgh's family in 1969. The books were assumed by the University Library.
