This series contains materials related to the Cooperative Commonwealth Federation's BC and Yukon chapter, as well as some early BC NDP materials.

The Cooperative Commonwealth Federation (CCF), widely considered Canada's first socialist political party, was founded in Calgary, Alberta on July 31, 1932 by a gathering of socialist and labour groups, and political activists, brought together by the increasing challenges of the Great Depression. The party's first leader was James Shaver Woodsworth, a former Methodist minister, social activist, and outspoken Member of Parliament. The BC section of the CCF was formed in 1933 by a coalition of the Socialist Party of Canada (BC), the League for Social Reconstruction, and other related organizations. In the 1933 provincial elections, the new provincial party managed to secure enough votes to become the official opposition until 1937. In 1961, the federal CCF changed its name to the New Democratic Party, following an alliance with the Canadian Labour Congress; most sections quickly followed suit.

Records in this series are by no means a complete portrait of CCF years; rather they appear represent stray records donated by retiring NDP members or found in the provincial office. Items in this series include correspondence, meeting minutes, reports, clippings, CCF convention materials, budget documents, early NDP publications, and other related materials.
