It includes some 2714 books and periodicals from the nineteenth and twentieth centuries on the puppet theatre in various European languages as well as scripts for puppet plays.

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.
