This series of microfilms was largely made originally for the Commonwealth National Library, Canberra, Australia; Mitchell Library, Sydney, Australia; and Department of Internal Affairs, Wellington, New Zealand. These copies were the property of the Public Record Office prior to their addition to the R.G.O. Archives. RGO 36/3/1b, 2b and 3b were made by Cambridge University Library circa 2004 and were added to the series by the cataloguing archivist in March 2009.
