Most of the collection consists of letters from Floyd Dell to writer Miriam Gurko concerning Edna St. Vincent Millay, and copies of letters containing Gurko's responses. The correspondence, which concerns the Dell years with Millay, began in 1960 and continued until 1968. Gurko's never-published draft manuscript containing Dell's letters about Edna St. Vincent Millay is also included in the collection.

Collection also contains some notes of Gurko's and several short works of Dell's, including a manuscript typescript of "Not Roses, Roses All the Way: Some Recollections of Edna Millay," 1963. Also, two letters Dell wrote to Allen Churchill in 1958 that Churchill gave to Gurko with an undated covering letter.
