In this age, knowledge was very expensive, which led to the spread of mysterious knowledge from individuals to individuals, and the appearance of private libraries. It was said that before the catastrophe, there were large-scale public library in many cities and regions. Those libraries would always contain tens of thousands, hundreds of thousands of books, or even millions of books. At that time, people could absorb the knowledge that they needed from the sea of knowledge at the cost of little money or none at all. However, in this age, that kind of scene was completely unimaginable.
As far as Zhang Tie knew, there wasn’t a single public library in the entire Andaman Alliance, even across the whole Blackson Human Clan Corridor. In this age, all the libraries were private, while all the books were very important personal assets. To manage a private library was the same to managing a plant or a shop as they could all bring you profit.
