I am currently reading the light novel and I’ve really been enjoying the description of how the supply lines are created and developed. Everything is so great and makes sense except for one thing. Where is all the paper coming from? There is no mention of supply lines for paper and with the centralized bureaucracy that Roland develops must go through tons of paper every day. No mention of paper mills, no mention of purchasing paper, and no mention of the printing press. Are all the books for the schools made by hand? Every supply line is mentioned except for this crucial one.
