Barbara Steveni's diaries and calendars The diaries mainly record appointments but do include journal entries by Barbara Steveni from the 1980's onwards. Some of the early diaries are in several hands, including John Latham's. Two diaries of 1976 and 1993 are those of John Latham but have entries written by Barbara Steveni, evidencing their close working relationship. The wall calendars detail Barbara Steveni's daily appointments and movements. They are missing for 2009-10 and there are two calendars for each of the years between 2013-16. 1966-2020
