Isn't this a bit skewed though? I've not read maybe half the books in my library, but that's simply because either I bought something like a humble bundle where I was only really interested in 2-3 of them anyway, or because I bought whole series at discounted price and stopped after first two books.

Kind of similar to Steam games - 37% of games were never played. If I can get a set of Witcher 1,2,3 for the price of one + $1, then I'm definitely getting all of them, even if I'm really interested in the third one only right now.
