Tabulated account of his life and activity, drawn up by Strachey. The information, itemised by year and by month, is compressed in Strachey's very tiny handwriting on to 2œ sheets of writing-paper. The earliest entry is for 1926, and the entries have been added in blocks of two or three years at a time, to the end of 1964. Personal and professional events are recorded, and the account is remarkable for the amount of information encompassed.

Address books (8) and loose pages of addresses. One of the books bears a note by Mrs. Halpern (Strachey's sister): 'must have been started some time in the 1930s at latest'.
