The collection consists of seven volumes of Elliott's personal diaries, which were bound together, at his own expense, after their completion. These diaries cover the five-year period that Elliott spent serving overseas, primarily in England. The contents of the journals include handwritten entries, sketches and watercolours that were either executed in the pages of the diary or pasted in, and photographs, newspaper clippings, letters, playbills, menus and other paraphernalia that were also pasted into the diary. These serve to document both the development of the war and Elliott's personal experiences. The diaries are generally in chronological order although there are places, particularly in the last three volumes, where the diaries have been bound out of sequence.

The fonds also contains several folio sheets of photographs and clippings regarding Elliott's career.

Laid in at p. 207 is an ink blotter featuring pharmaceutical advertising for Glyco-Heroin (Smith).
