Warren’s manuscript files (1959-2015) sub-series includes drafts, research notes, and correspondence related to the publication of books and articles. The manuscript drafts consist largely of research notes from the geologist and archaeologist William Pengelly, Brixham Cave, Charles Lyell and Hugh Falconer in England, on which Warren published articles. The manuscript drafts also contain research files, correspondence, and full publications for Warren's Purple Hummingbird: A Biography of Elizabeth Warder Crozer Campbell.
