During the 1930s the Japanese Government General of Korea’s Society for the Compilation of Korean History commissioned facsimiles of some 21 rare historical sources to accompany the publication of the colossal History of Korea (Chōsenshi 朝鮮史), funnelling select xylographic, typographic, and chirographic products of the defunct Chosŏn dynasty’s book ecology through offset lithography and collotype, and on occasion movable type. This article investigates the Society for the Compilation of Korean History’s collection and classification of historical materials against the larger backdrop of colonial knowledge production, illuminates the different economic and editorial logics of the new printing technologies used to produce the facsimiles, and examines the products as one example of the significance of facsimiles in the field of history. It suggests that the interplay of traditional print media, dominated by woodblock prints, and the new photomechanical means of reproduction, allowed for the swift reproduction of the unfolded page image and the easy utilization of traditional-style binding, permitting the Society to create purposefully antiquated reproductions with a high degree of fidelity to the original. At the same time, the use of modern materials (paper, string, and covers) and certain features common to traditional Japanese book binding meant that the facsimiles were irrevocably hybrid. These facsimiles ended up in a wide range of research libraries, representing the Korean past to the scholarly community in the Japanese empire.
