The George Hill fonds documents a period of 20 years of the Dominion Tar and Chemical Company Canada Creosoting Division, Canadian Pacific Railway (CPR) creosote plant in Sudbury. Composed of photographs, a notebook of memorabilia with a preamble, records from the plant, and maps relating to the CPR Creosote plant in Sudbury, the fonds provides an overview of the operations and the workflow involved, but also illustrates the layout of the plant, including the different buildings and machinery. The preamble, consisting of comments and explanations by Hill, provides an understanding not only of the set up required to process creosote, but also of the different steps involved. Moreover, an engineering blueprint of the layout of the plant with references to photographs and annotations by George Hill offers a visualization of the plant and the machinery.

Sheets of wages, lists of employees and their roles at the plant, and a grievance on the work conditions complete this comprehensive presentation on the CPR creosote plant.

The CAVM Photograph Collection was gathered by the National Aviation Museum over time in order to preserve a visual record of aviation in Canada. The Museum used these photographs in exhibits, for historical reference, for reference in constructing models, and for restoration projects. Some original photographs (prints or negatives) were added to the Museum’s permanent collection, but selections were also made from photograph albums, scrapbooks, and prints, that were then copied and returned. Contributors may have been the original photographers, sharing or donating their own work, or aviation enthusiasts or historians that had copied photographs from other collections. Many small groups of photographs were donated by individuals and families with connections to aviation. The Museum created preservation copy negatives of the selected photographs, giving each copy negative a sequential number. The Collection is arranged in three series: CAVM-1 Negatives, CAVM-2 Prints, and CAVM-3 Card catalogue. The card catalogue was created to facilitate access to the Collection. Each card has information on the photograph with a small print glued to the card as a visual reference. The catalogue has five Photographic Print (PP) sub-series: PP01 General Aircraft by Manufacturer; PP02 National Aviation Museum Collection (historical photographs of Museum aircraft or conservation photographs taken by Museum staff); PP03 People, Organizations, Events, Gliders/Blimps, Airports/Air Fields; PP04 Hawker Siddeley Canada; and PP05 Miscellaneous (Museum displays, events, public relations, staff, site, models and engines).
