F-14 contains documents 313255, 313255A–F. They consist of a file folder of Blackwell's with notes as well as draft index to Vol. 2 of BR's Autobiography. There are also many pages by him on a draft or drafts of Vol. 3. Pages are headed "Notes on BR's Autobiography Vol III" (18 pp.) and "Literary Notes on BR's Autobiography Vol III" (5 pp.); and several more pages (3 not by Blackwell).

The folder has an undated note in Blackwell's hand addressed to "Bill": "I thought you might like to take a closer look at what I found today. [T]hey're in my very own typewriting on an electric IBM! [B] do leave them out here -- I need them for work today." "Bill" could be William Sorsby, with whom and his wife Blackwell was sharing rental quarters. The IBM typing was likely what he found in researching at the Public Record Office, London, in the Home Office files on BR. (Sorsby was also researching at the PRO.) The typescript was sent to BR.
