The thing with WT literature it's so convoluted it's almost impossible to read unless you''re already indoctrinated that's why there are seperate more topical subjects for the public and different reading section for the members.
I don't think their goal was to simply proliferate the books as religious works in themselves because most of it goes into a cupboard or the garbage unread. Having said that WT have always loved to brag about the numbers of books printed and placed for the sake of providing proof to the claim that they are "blessed by Jehovah."
So the mulitiude of books and mags tally would serve that purpose whether they were read or not. I think WT would prefer that anyone with half a critical thought in their head didn't read their religious claptrap.
