The Harper Collins paperback copy that Sharlene has, has "Conan" rather than Cohan on the front cover. I would have responded sooner, but I couldn't find the book.
But I don't think this is a mistake - the blurb on the front is saying what Terry is parodying in the book - "From the apocalypse to Conan the Barbarian, more sidesplitting Discworld fun!"
