In 1970, the Institue of Modern History, Academia Sinica, selected a part of the nine sets of materials and the Microreproduction Service, Harvard University Library, made these materials into 111 reels of microfilms. These 111 reels of microfilms become the invaluable set of primary materials to research the economic history of modern China as the original paper copies are hard to locate now.
