The blog added up literary prizewinners and nominations, counting two points for every time a novel was shortlisted for a literary prize and three points for every win. The list of counted awards included: Booker Prize, National Book Critics Circle Award, International IMPAC Dublin Literary Award, National Book Award, Pulitzer Prize, and the Costa Book Award.
Here’s the methodology behind the count: “Because I wanted the British books to ‘compete’ with the American books, I also looked at a couple of awards that recognize books from both sides of the ocean, the National Book Critics Circle Awards and the International IMPAC Dublin Literary Award. The IMPAC is probably the weakest of all these, but since it is both more international and more populist than the other awards, I thought it added something. The glaring omission is the PEN/Faulkner, but it would have skewed everything too much in favor of the American books, so I left it out.” (Via Publishers Weekly)
