Forgotten Journeys: The French Bestsellers That Shaped American Exploration is an environmental intellectual history of early America. It tracks the circulation of bestselling French books about the natural history and geography of Canada and Louisiana for readers in the eighteenth-century French and British Empires. The presence of French titles in early Anglo-American library collections, lists, commonplace books, and manuscripts uncovers the amalgamated non-Anglo origins of European knowledge about early America. Through the circulation, translation, and abstraction of indigenous knowledge by Francophone then Anglophone authors, Forgotten Journeys shows how indigenous information is transformed and tracks the transformations it underwent. My research reflects interdisciplinarity and has the potential to contribute to the public history of science while showcasing actors hidden or obscured through printed texts.
