The Sims family collection encompasses records of the Sims and Cook, Davidson and Garden families retained by members of the two family branches that came together when Harvey James Sims and Florence Katherine Roos married in 1902. Their Sims and Davidson forbears were equally significant in the history of the Waterloo-Wellington area and in the growth and development of agriculture, education, business and government. Harvey James Sims and Florence Katherine Roos were deeply involved in their local community of Berlin, (later Kitchener) Ontario and their own records contain significant additions to our knowledge of local personalities and affairs. Harvey was a childhood and lifelong friend of William Lyon Mackenzie King; they wrote and visited each other regularly. King's sister Bella was also a close friend of Florence from school days on.

Anonymous open letter created by a group of feminists from Québec outlining the outcomes from the October Crisis (Québec, October 1970) and the relationship between Québécois feminist movements and the Front de Libération du Québec (FLQ).

Letter begins by explaining the relationship between the FLQ struggle and women’s struggle. It then moves to an overview of the events that lead to the October Crisis and the invocation of the War Measures Act, while calling for an independent Québec. Later, it covers the effects of the October Crisis for the citizens of Québec in general, and for women in particular (retelling raids, questionings, jailing, and overall police activities and attitudes). It continues with an exposition on women's inequality in government and society. The letter finishes by appealing for support to the FLQ and the women’s movement.

Letter seems to have been written shortly after the invocation of the War Measures Act in October 1970, and a year after the Women’s Movement in Québec began (possibly refers to the Québec Women’s Liberation Front (FLF) created on December 1, 1969).
