This series primarily consists of professional correspondence. Louise Creston acted as her husband’s personal archivist, and for this reason, most of the material in this series has remained in the order she organized it. The series includes letters, postcards, telegrams, promotional flyers, and contracts from 1923 to 1985. The vast majority of the correspondence is typed letters with signatures. Creston often typed his reply on the back of the letter to which he was responding. Other material in the series includes: invoices, programs, reviews, reports, royalty statements, articles, pamphlets, and photographs. Also contained in the series are letters to Louise written after Paul passed away. Correspondence about Creston’s trips to Europe, Tel Aviv, and Turkey can be found in the Diaries & Autobiographical Information series. Correspondence is divided into eight sub-series: A. Colleges and Schools, B. Conductors, C. Orchestras, D. Organizations, E. Personal Correspondence, F. Publishers, G. Radio Stations and Television Networks, and H. Recording Companies. The items are arranged alphabetically within each sub-series. Sub-series A includes letters from Central Washington State College, where Creston taught. There are handwritten thank you notes from elementary school children and correspondence to Grinnell College containing letters to and from the Mirecourt Trio. Letters to and from famous conductors such as Monteux, Ormandy, Stokowski and Toscanini can be found in sub-series B. Other letters to orchestra conductors can be found in sub-series C. Leonard Burkat can be found in this series but he is not a conductor; he ran a program note service. Sub-series C contains a list of names and addresses of orchestra conductors. Letters to specific orchestra conductors can be found in sub-series B. Organizations to which Creston belonged can be found in sub-series D. There is correspondence to and from ASCAP (American Society of Composers, Authors, and Publishers). Creston belonged to ASCAP most of his life and received royalties through the organization. Included are lists of original manuscripts Creston donated to the Library of Congress. Surveys do not refer to an organization but are surveys on the most frequently performed 20th century orchestra compositions. The correspondence in sub-series E contains primarily professional correspondence to individuals that are not conductors. There are form letters from Creston, letters to and from his family, and handwritten 75th birthday cards from elementary school students in Kansas. Sub-series F includes correspondence to and from publishers of Creston’s music and books. Creston published the majority of his work with Belwin-Mills, Exposition Press, Franco Colombo, G. Schirmer, and Shawnee Press. Correspondence to Mills Music can be found under Mills Music or Belwin-Mills because the two companies merged. Correspondence from stations that programmed Creston’s works can be found in Sub-series G. There are 11 radio interview scripts discussing Creston’s music and philosophy. Sub-series H includes companies that recorded and distributed Creston’s works. Recording contracts are also found in this series.
