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.

The bulk of the correspondence is from the 1930s until Wright's death in 1959.

Wright's work and ideas were exhibited throughout the United States and Europe on numerous occasions during his lifetime. This collection represents over 40 of those different exhibitions and includes shows mounted by Wright as well as those mounted by some of the most established curators and institutions of the time. Highlights in the collection include papers on Wright's first traveling show in 1930, a scrapbook compiled by H.T. Wijdeveld celebrating the exhibition he organized for Wright that toured Germany and Netherlands in 1931, and correspondence and other papers related to the many Sixty Years of Living Architecture shows throughout the United States and the world.
