The archive also includes the composer's original arrangements and adaptations for his own songs and for songs by others, photographs, letters, notebooks, journals, documents, programs, posters, and newspaper clippings including critiques, articles, and interviews. Many recordings of his songs can also be found in the Music Department's Sound Archive.
