Korean language materials at the University of Chicago can be searched using either original Korean scripts or the McCune-Reischauer Romanization system. The McCune-Reischauer romanization system was created in 1937 and currently is used for standard romanization library catalogs in North America. In 2009, the Library of Congress released the revised McCune-Reischauer Romanization system and word division.
