"These books are created in the shape of their original books using the help of the inter-realm city's feature. And the appropriate offering required to create each book varies based on the nature of their content," Dredre answered. 

As I suspected, the books in the library were also the creation of the devil merchant code. I had my reason when I was stumped hearing Dredre say that there were about 82,876 books just on the prices of various items. The first reason was that all of these countless books were soul energy constructs just like the entire inter-realm city. And the second reason was that I was having a hard time believing that a demon/devil merchant spent a shit load of offerings to create these books to open a library.
