Jean,

No worries, and thanks for the clarification.
You’ll find the introduction to the two previous publications here:

Whilst Paquette does have a very clear focus on the mid to late 18th century, he is extremely knowledgeable about, and draws on, historiography of the preceding centuries of discovery, conquest and colonisation of the Americas for both of these pathfinder countries.
