The strength of the collection is the discovery and exploration of North America. Among the earliest accounts of voyages to North America is Ramusio's Navagationi et Viaggi (Venice, 1556). Maps of discovery include Cornelius Claesz's Nova Francia (Amsterdam, 1594), Willem Barents Deliniatio Cartae trium navagationum (1598) and Hessel Gerritsz's Tabula Nautica (Amsterdam, 1612). Manuscript plans of New France by Jehan Bourdon dated 1635-1642, are also worthy of mention. Some of the notable maps of New France are included in a set of fifty maps (1556-1850) donated by McGill graduate and management professor William H. Pugsley (1912-1993). These maps are complemented by the sixty-four maps (1597-1857) donated by Alfred J. Pick. As well, there is Admiral Henry W. Bayfield's Charts of the River St. Lawrence (1828-1865).
