The project files which occupy most of the archives of J.T. Donald and Co. fall into two series: ordinary business and special assignments. Both series contain the firms report's, and correspondence. Special assignments were largely connected with wartime armaments production. A few files concern work for the Imperial Munitions Board in World War I, but most consist of reports for the Chemical and Explosives Branch of the Department of Munitions and Supply, 1939-1948. Ordinary projects involve consultation for food, pulp and paper, petroleum, and chemical manufacturies, as well as for some government departments, 1888-1940. Outgoing correspondence from 1881 to 1909 is contained in letterbooks. A file of legal documents, 1924-1946, refer to claims against the company, agreements, and partnerships. Also included are an undated notebook on chemical analysis, and scrapbooks and files of newsclippings of professional interest (e.g. reports of explosions caused by oil and gas) covering the period 1916-1958. There are also reports on mining and energy sources prepared by Donald alone and also in partnership with J.H. Ross for various private and government bodies.

Consists of microfilm of originals, located at Library and Archives Canada. The records of the Board of Trade fall into two series. Administrative records comprise the register of the Committee of Trade, 1822-1842; followed by the minutes of the Board, 1842-1952; reports of general meetings, 1842-1951; and annual meetings, 1876-1879; and council annual reports, 1886-1931. Correspondence consists of letterbooks, 1870-1920, and the correspondence files of the Committee of Trade, 1822-1842. A review of the activities of the Board from 1950 is also included.

These scattered items of correspondence deal with Porter's resignation from the Cincinnati, Hamilton and Dayton Railroad Co. (1892), stock purchases (1907) and other financial matters (1927-1928).

Fonds consists of records (originals, printed materials, photographs and motion pictures) that are almost entirely of a professional and research nature, covering Barnes’ general scientific and university work during World War I, a number of special research problems, and his involvement in scientific and social organizations.

His general scientific and university files (1914-1915) contain correspondence, including copies of some of Barnes' outgoing letters on departmental adminstration, Barnes' lectures, publications, scientific apparatus, research problems and the exchange of information. Correspondents include colleagues in other institutions (including Ernest Rutherford), learned societies, and private industry. This series also contains a file on purchases for the University Library, and inventories of Barnes' library.

Far more extensive are the materials on special research problems. These comprise notes, essays and correspondence on the detection of submarines (1915-1917) and on the development of anti-freezing devices for fire extinguisher and sprinkler systems (1917). A report by Barnes on the effect of ice conditions on St. Lawrence navigaton is supplemented by printed background materials and copies, or extracts from other reports. Barnes' work on icebergs is documented by five binders of clippings, photographs, maps and diary notes on research expeditions to Newfoundland (1924-1929). Practical experiments in ice clearance are illustrated by bound notebooks of clippings and photographs, as well as a number of loose photographs showing ice and flooding damage, use of thermite and calcium chloride, apparatus and ice-crushers (ca 1921- 1929). Finally, two reels of 35 mm motion picture film (ca 1930) show Barnes experimenting with a new mercury microthermometer.

Barnes' work as Hon. Secretary of the Canadian Committee of the British Science Guild is documented by correspondence from 1907 to 1919, largely concerning the recruitment of members and officers, but also touching on a survey of science teaching in schools and the Panama-Pacific Exposition of 1917. Less extensive files cover Barnes' involvement in the International Council for the Exploration of the Sea (1912-1914), the Rotary Club (1917) and the McGill Graduates' Society (1919)

These papers concern the work of the committees on which Beach served from 1962 to 1969, and contain correspondence, memoranda, proposals, and reports, mostly for the Academic Policy Committee and the University Libraries Committee.
