Arctic history is suddenly hot. An exhibition currently on view at the British Library - Lines in the Ice: Seeking the Northwest Passage - is bringing attention to early prints and maps of the Arctic and to the historic search for the Northwest Passage. Earlier this week an article published on Slate's history blog The Vault highlighted images from a 19th-century British expedition of Baffin Bay captained by John Ross. The images in the Slate article are all drawn from the John Carter Brown Library's superb online Archive of Early American Images. And they're just the tip of the iceberg. The collection, which is hosted through LUNA, contains beautiful historic illustrations from a number of Arctic expeditions and whaling voyages, and the surreal landscapes are definitely worth exploring.
