Over the past decades a vast amount of often full-text searchable newspaper and other source material from modern East Asia have been made available for research, much of which is in Western languages. The sheer wealth of detail has brought new challenges to research on the region in terms of methodology and theory. Studies on Modern East Asian History is the prime publication vehicle for monographs and edited volumes on the period of large-scale Western interaction with the region from the Opium Wars in the mid-nineteenth century right up to the Korean War in the early 1950s.
