Fonds consists of research material and oral history interviews conducted by Merrily Weisbord for the writing of The Strangest Dream. The interviews cover various aspects of the evolution of the Communist Party of Canada (renamed the Labour Progressive Party in 1943) and the life of some of its Quebec members.
Fonds includes more than 20 hours of sound recordings consisting of interviews with about fifteen individuals who were members of the party between the 1930s and the 1950s, such as Lea Roback, Irene Kon, Gilles Hénault and Fred Taylor. All the players, from the upper middle class intellectual Stanley Ryerson to the working class lumber camp labour organizer, Gérard Fortin, are included. There is also a 15 minute recorded message by Paul Robeson urging Montreal voters to reelect Fred Rose in 1945. Fonds also includes interview notes and transcriptions, correspondence, and printed materials.
