Contains a number of draft manuscripts of MHB's book on the Dnipro River, which she was working on at the time of her death and which remains unpublished. It is variously entitled "The Dnipro River of Ukraine: Its Life; Its Times", "The Ninth River" (referring to its world rank in terms of length), or "Fabulous River: Story of the Dnieper". It includes an early 1985 holograph draft, two typescript drafts of approximately 300 pages from the 1990s, floppy discs, a manually assembled panorama photograph, and bibliographic material.
