This collection is a mixture of material created by Joseph Cook, and material gathered by Mrs Mary Wood, his granddaughter. It consists of a small number of notebooks, a commission as NSW Secretary for Mines and Agriculture, an illuminated address, the text of the Treaty of Versailles, a passport, photographs, newspaper cuttings, and miscellaneous printed and photocopied material relating to Cook. The first part of this material was donated to the Library in 1968 by Mrs Wood. Subsequent material, also originating from Mrs Wood, was purchased from a book dealer in 1995.
