Many of the personal photographs depict members of the Masson family taken in Terrebonne, Quebec (where the Masson family home was located), in Ottawa, and during travels to Italy, London, the south of France. There are 28 leaves of full page plates of travel photographs from France, Italy, and Africa. Also included in the album are postcards and newspaper clippings. One series of postcards depicts architecture in Terrebonne, Quebec. The clippings include a letter to the editor written by L. R. Masson (Mrs. L. A. Globensky) and published in the Montreal Star, 1939. Other clippings relate to the S-Plan, a bombing campaign by the Ireland Republic Army, in 1939, as well as the British royal family.

This collection consists of scrap books of prints and letters, mostly concerning Canada or Montréal compiled by Sandham.

The collection comprises more than 6,000 Canadian and non-Canadian bookplates. The Masson collection reflects the range and scope of the art of bookplate design, mirroring period styles and incorporating the owners’ personal tastes and pursuits. References to heraldry, literature, nature and art are common. The collection was created by Montrealer Philippe Masson (1911-1944) and includes both personal and institutional plates. The nearly 3,000 Canadian bookplates are arranged alphabetically. The rest of the bookplate collection is divided between armorial and non-armorial plates. This unique collection represents a wide range of book ownership reflecting institutions, book sellers, and individuals as well as over one hundred examples of bookplates from Canadian libraries. The chronological coverage dates to more than a century from the early nineteenth century and continuing to the beginning of the Second World War. Bookplate design is a minor yet notable form of graphic design. Bookplates reveal a great deal about our book-centered culture. For many institutions, bookplates possess an iconographic or emblematic value reflecting the values of the institution. As well, within an institutional setting, bookplates are often used to acknowledge individual collections, gifts and bequests. Finally, for the individual the bookplate is a powerful symbol of possession and a love of books. Among the Canadian bookplates, many well-known Canadian artists are represented in the Masson collection including J. E. H. MacDonald, his son Thoreau MacDonald, Jean-Paul Lemieux, and W. F. G. Godfrey.

The fonds documents the activities of Bruce Whiteman as poet, bibliographer, scholar and editor. It also contains, through correspondence and manuscripts, useful and important information on other leading contemporary Canadian poets.

The fonds includes personal and professional correspondence, 1991-1993; research notes, typescripts, drafts, and corrected proofs of manuscripts; and minor writings (reviews, short poems, bibliographical articles).
