Sources: Various material contemporary with the war have been used to compile The Great War On This Day and its associated Compendium.

On This Day pages are styled as timelines and have been transcribed from two out-of-copyright sources: Chronology of the War (1918-1920), and History of the Great War – Principle Events 1914-1918 (1922). The spelling of place-names is a particularly convoluted subject. Some names were spelt differently depending on source, others have changed over time for various political or geographical reasons. In general, spelling of place names are original to British use at the time of, and shortly after, the war. Some typos have been altered or corrected for consistency. Similar events between these sources have been amalgamated; as a result the date and wording may differ to their original texts.

Compendium entries form the central hub of (a) An index-like collection of places, people, ships, battles, political events, etc., and (b) Words and phrases of the Armed Forces of Great Britain during the Great War. The majority of these have been transcribed from Chronology of the War (1918-1920) and Soldier and Sailor Words and Phrases (1925) respectively, the later which is reflected in the language used and some may seem derogatory by today's standards.
