There are many questions where the answer is absolute, as an example on this page. The question of which companies manufactured a rotary engine motorcycle ( the answer Hercules and Suzuki in the 1974 ) Or for which event was the slogan " Keep calm and carry on" was used for. ( The British government used it for WWII )
On the question of which book is the most published after The Bible and Harry Potter, it is debatable. and would depend if go by the definition of a book as printed paper bound together in a volume as a book or do you define a book as only classical literature. In the end it is all for fun and trivial knowledge.
