This chapter outlines an international collaboration model for a digitization project between an American academic library and Japanese national library. University of Maryland Libraries (UMD) partner with the National Diet Library of Japan (NDL), the Japanese equivalent of the Library of Congress. They collectively pursue a bilateral digitization initiative, “Book Reformatting Project,” which aims to preserve and create digital access to the materials held by the Gordon W. Prange Collection. Prange Collection is one of UMD’s premier special collections, which comprehensively archives Japanese-language print publications issued for the first four years of the Allied Occupation of Japan, 1945-1949.
