Drafts and research material for Jones' three-volume biography of Freud. For each volume, there is a series of drafts of chapters with associated research notes and amendments, followed by general research notes and amendments. It should also be noted that Jones sometimes used the reverse side of letters as notepaper and so various items of correspondence, including letters from his publishers, can be found amongst these papers (although most have been removed from the drafts for Volume I - see P04-A-E-01).
Also included are other research materials gathered by Jones from various colleagues and relatives of Sigmund Freud; these are placed last.
