Before and after the 1990 20th-century-authors volumes were included, additions to the "Great Books" main entries were also published from 1953 to 2002 in the "Great Ideas Today" yearbook series volumes (matching the styling of the set like updates to encyclopedias are). The first work from the modern world (some of the races of authors in the ancient world are unknown) chosen for inclusion in these additions to the Great Books main entries by a black author was "The Souls of Black Folk" by W. E. B. Dubois (1903).
