This text covers 280 years of North American exploration and colonization efforts, ranging geographically from Florida to the Arctic. Arranged thematically and mononationally, the work focuses on a selection of 10 explorers who represent the changing course of North American exploration during the early modern period. The use of biography to narrate this history draws in readers and makes the work accessible to both a specialized and general audience. The dozens of primary source documents in this guided source reader span travel accounts, autobiographies, letters, official reports, memoirs, patents, and articles of agreement. This wide variety of primary sources serves to bring to life the failures and triumphs of exploring a newly discovered continent in the early modern period. This work focuses on ten explorers, including those who are well known, including John Cabot, John Smith, Jacques Cartier, and Samuel de Champlain, as well as discoverers who have slipped from our modern historical consciousness, such as George Waymouth, John Lawson, and J.F.W. Des Barres. The documents that narrate the voyages of these adventurers are arranged chronologically, vividly telling the story of historical events and presenting different voices to the reader. This variety of viewpoints serves to heighten readers' critical engagement with historical source material. The vast variety of primary source materials present students with the opportunity to read and engage critically with different types of historical documents, thereby growing their analytical skillsets.
