The Archives of the Morgan Library & Museum hold correspondence between Greene and colleagues at NYPL that provide additional details about the planning of Original Manuscripts and Drawings of English Authors from the Pierpont Morgan Library. A letter to Greene from Director E.H. Anderson, dated July 10, 1924, responds to her query about mounting a “large, important, and really interesting Exhibition of English Literary and Historical Autograph Manuscripts” in NYPL’s exhibition space. Citing the requisite consent of NYPL’s Executive Committee, Anderson assures Greene “there will be no difficulty in securing their hearty approval.”
