The collection is classified into approximately 40 series representing broad subjects, periods of regimental history, and units within the regiment. Many of the series are further divided into sub-series. Files are generally described to the item level. The collection consists of correspondence, nominal rolls, ledgers, scrapbooks, war diaries, Part I and Part II Orders, maps, blueprints, annual reports, meeting minutes, newsletters, magazines, newspapers, clippings, programmes, posters and personnel documents illustrating regimental activities and achievements during war and peace times and the length of service, number of casualties and honours and awards of past and present members of the Regiment. Also included is biographical information on the Colonels-in-Chief, Colonels of the Regiment and other Regimental personalities.
