The reference notes are a link to much more in-depth information. I flag this up by using a traditional serif typeface, which is a style associated with knowledge and information. I chose Monotype Century Expanded, designed by Linn Boyd Benton and T. L. DeVinne (1894), because it has the right tone of voice and elegant italics.
Finally, the cover (top) is designed by Two Associates who used a headline version of the Franklin Gothic body copy. I think the bold, tabloid newspaper style suits the title well.
