Alternate history is a long-established subgenre of science fiction. “But one of the deepest pleasures of alternate histories are their maps. Sometimes these allow stories to unfurl, or complement the hypothetical world of a tale being told. But in many cases, the map alone tells a story,” writes Samuel Arbesman in a piece exploring alternate history and its maps at BBC Future. It’s a 101-level piece insofar as alternate history the subgenre is concerned; the pleasure, as you might expect, is the maps shared and linked to. [ICA]
