And who else?

I've recently started reading a novel by the Huguenot minister Joseph Sortain, Count Arensberg; Or, the Days of Martin Luther (2 vols., 1853), and I'm intrigued by the download counts.  Well, for starters, by the fact that there are thirty-one downloads for the second volume but only eight for the first  (I suppose that's one way to get things over with quickly), but, more to the point, by the fact that there are any downloads, period.  Who else is reading this novel, I wonder? (Or are all the downloads from the various POD companies that are trying to cash in on the free online versions?)
