René Bouchard, Pointe-à-Callière, City of Montréal archaeological collection.

True storehouses of knowledge, libraries held more than just books. They also contained scientific and technological objects, including a three-dimensional model of the solar system as it was understood at the time, along with several terrestrial globes—prestige objects.
