The collection includes over 140,000 pages of correspondence, which serves as a core resource for understanding Wright's personal and professional activities, relationships, and ideas. The correspondence also includes project records such as specifications, contracts, supply orders, invoices and receipts. Letters from the 1880s through the 1920s accounts for only 2% of the total correspondence in the collection (approximately 2,000 documents). The bulk of the correspondence is from the 1930s until Wright's death in 1959.

This collection of approx. 7 linear feet of papers documents the output of the independent printing press established at Taliesin in the 1930s. The collection consists of brochures, pamphlets, newsletters, Taliesin magazines, festival programs, invitations, and miscellaneous ephemera such as Christmas cards and stationery. The collection also includes every issue of the Taliesin Square Papers series dating from 1941 to 1953. All of the printed material in the collection features the distinctive graphic design associated with Frank Lloyd Wright. Much of the graphic design work can be attributed to Eugene Masselink (1910-1962).
