Harkin relied on free publicity to promote tourism. The Parks Branch Annual Report outlined the commercial and humanitarian benefits of parks. These mandatory publications were sent to Members of Parliament and newspapers across Canada. They became the Parks Branch's initial marketing tool. In the 1920s, Harkin appointed Mabel Williams to author guidebooks and literature that promoted parks as a Canadian birthright that made one physically stronger, psychologically renewed, and spiritually fulfilled. With increased tourism, the Branch could afford printing the guidebooks. Their spending in the government printing department jumped from $2000 to almost $13,000 in one year. The Parks Branch created a Publicity Division to promote Canada's parks through guidebooks, lectures, slide presentations, and motion pictures. This successful division would later form the Canadian Government Travel Bureau and National Film Board of Canada.
