I tried to get some of the same statistics a few years ago and was 
surprised at how little detail I was able to find.  I also wound up 
at "Nielsen BookScan," but IIRC you have to subscribe to get any 
real details.  I think that, for your purposes, just some overall 
stats to compare the sales volumes of the 3 different book series 
you're talking about would suffice.
