Between 1680 and 1807 several British publishers produced a sequence of double-hemisphere world maps, each printed on two conjoined sheets. The British Library holds the most comprehensive collection of these important maps, and this is the first time that this type of map has been studied as a genre, partly because of their great rarity.
