Ontario's rich and diverse past provides many vivid narratives for writers and historians, and since 1903, the Archives of Ontario has been the central repository for the province's history. With a collection of over 3.5 million photographs, 35 000 maps, and 150 000 architectural drawings in its downtown Toronto site, the Archives offer Ontarians extensive access to their collective history. The Archives of Ontario is celebrating its 100th anniversary in 2003 with the publication of this volume. Showcasing a broad cross-section of items, Treasures of the Ontario Archives, commemorates Ontario's heritage through promotion and explanation of the Archives' collections, which include amateur and professional photography, the Government of Ontario Art Collection, cartography, photo-journalism, important government documents, and twentieth century architecture. With each chapter highlighting a specific collection, the book has more than 300 photographs, maps, and other images. With an introduction from the chief Archivist and a congratulatory note from Ontario's premier, 300 years of economic, social, political, and cultural development are being recognized in a very important publication.
