I suppose that some of the work in this set, written between 1916 and 1932 and reisused in the 1960s, and again around 2008-2010 has been changed by more recent scholarship, but there is still nothing to equal this fantastic achievement. It includes not only the more familiar myths such as Greek and Roman, but pretty well succeeds in its goal to include all of humanity. The text is extremely detailed but very readable; none of the turgid prose so often associated with academia. One of the most useful parts of the set is the 13th volume, an extremely detailed and completed index, which allows the reader to pursue a theme, or even a topic as specific as the significance of belts, across all the volumes.
The first twelve volumes deal with the mythology of particular regions, as noted in the titles. Although there is not an individual index, the table of contents is fairly detailed, so information can still be retrieved. The volumes include a number of plates, mostly in black-and-white, with line drawings included in the text. The hardcover books appear to have been issued without dust jackets
