Why is your Gone With the Wind book dated in roman numerals?

Books are often dated in Roman numerals to give them a classic or timeless feel, reflecting the tradition of using these numerals in historical and literary contexts. In the case of "Gone with the Wind," this stylistic choice may also evoke the novel's setting during the Civil War and Reconstruction era, aligning with the book's themes and period. Additionally, using Roman numerals can add an element of elegance and distinction to the publication.
