This should be considered a family archive. It contains Sir John Logan Campbell's (JLC) personal papers (approximately 40%); his business papers (approximately 40%) and also an extensive collection of letters belonging to his wife Emma Campbell, daughter Winifred and other family members (approximately 20%). Of particular note are his "Reminiscences" (MS-51-1) and "My autobiography" (MS-51-2). Some documents relate to the purchase and development of land including One Tree Hill / Cornwall Park, as well as business correspondence for his businesses: Brown and Campbell (1840 - ??), Campbell and Ehrenfried, and McDermott and Campbell. It is a rich source of business and entrepreneurial history of the greater Auckland area, genealogy and family history, and JLC as an Auckland benefactor. There is also a strong collection of women's papers, exceedingly rich in social history -- a rare resource. These present a unique collection of particular interest to women's studies and social historians.

Correspondence relating to Brown and Campbell Ltd. reflects Logan Campbell's business acumen and follows his commercial interests from the early 1840s to the late 19th century - kauri gum and timber mills; farms and land speculation. Includes letters written to John Logan Campbell by his business partner William Brown, 1856 - 1864, 1884 - 1897, James Farmer, 1892 – 1893 and John Webster, 1900 - 1911.

Also included is correspondence between Campbell, his wife Emma and daughters Ida and Winifred while on an extended tour of Europe. Campbell had returned to New Zealand to rescue the floundering business while the women stayed on in Europe. Fortunately, Campbell kept copies of letters sent which complement the inward correspondence. There is also a sequence of letters for the period his wife and daughters stayed in Tasmania in 1875.

The collection includes letters from James Mackelvie, one time manager of Brown and Campbell, later a renowned art collector and Auckland benefactor.

Also landscape designer Austin Strong (New York), sculptor P.F. (Frank) Connelly (Florence, Italy) and Catherine Helen Spence, a fellow passenger on ship 'Palmyra' (1839 voyage) and later an Australian suffragette.
