The audiobooks for The Story of the World, Volumes 3 & 4 say "Revised" on the cover because the audios were originally sold by a different company and read by a different voice artist. When the former company's license ran out, Well-Trained Mind Press took over the production of the audiobooks. We changed the packaging to reflect our brand.
Jim Weiss is the reader for all 4 Volumes of The Story of the World.
We revised The Story of the World, Volume 3 in early 2020. The cover illustration for the 2020 Revision is that of a Native American woman. (The original edition's cover illustration is of a Native American man.)
