The collection consists of Edith Smellie's diary, a photograph, and notebook "Visiting List." The first section of her diary recounts a trip from Brockville, Ontario, to New York from October 2-10, 1888. She and her companions left Brockville by steamboat and transferred to rail at Morristown. The diary details visiting Central Park, the Metropolitan Museum of Art, as well as Macy's and other stores. The final pages of the diary contain calculations and a short list of purchases, including boots, shoes, paints, and collars. A few pages in the diary begin to recount a second trip in 1889, as well as some poems. In addition to the diary is a sepia cabinet portrait by Sheldon & Davis, Kingston. The visiting list contains numbered entries of visitors for 1897, 1898, and 1899. There are also some addresses.

The Penfield fonds consists of over eighty metres of Penfield's personal and professional records dating from his childhood up until his death in 1976, including during his career at the Montreal Neurological Institute. The materials in the fonds include photographs, correspondence, manuscripts and drafts of publications and speeches, research notes, glass slides, bound reports, films, and academic gowns.

The Julius Schloss Collection consists of Julius Schloss’s complete portfolio of published and unpublished compositions, sketches, studies and analyses. In addition, it contains documentary artefacts, including correspondence, newspaper, magazine and journal clippings, concert and competition programs, media reviews, and photographs, that chronicle both the early life of this German-Jewish composer in Europe and his later days in exile in Shanghai and the United States.
The content of the collection pertains to several lines of historical research: First, Schloss’s close relationship with Alban Berg as a personal assistant and chief copy editor, as well as his interaction with other contemporaries in Vienna during the 1920s, may offer new insight in studies of the Second Viennese School. The items of Bergiana, including a handwritten Baudelaire poem by Berg which served as a “secret program” to the Lyric Suite and a selection of correspondence surrounding Berg’s last wishes for the Lyric Suite score, are particularly valuable. Second, Schloss’s ten-year exile in Shanghai, documented in assorted correspondence, programs, reviews and miscellaneous artefacts, may provide a new account of the Shanghai generation. Finally, the continuation of Schloss’s life in the United States as a struggling composer and teacher bears witness to the difficult conditions for the American émigré population after World War II.

Macorquodale, Eng., explaining the donation in detail.

The papers are arranged into three series: 1 - Journals, 2 - Correspondence, and 3 - Financial and legal records. Documents in these series include a bound journal, correspondence, contracts, deeds of ownership, power of attorney, birth and marriage certificates, bills of sale, invoices, accounts, descriptions of political and military events, and genealogical notes.

Perley, the Chief Engineer of Public Works, on January 18, 1886, and January 28, 1886, in Ottawa, addressed to Antoine Gobeil, Esq., Deputy Minister of Public Works of the Dominion of Canada.
