The narh book is an example of the value that the Ottomans gave to their people.

Due to war or famine, production would decrease and prices would rise.

Naturally, the purchasing power of the people would decrease. Before Ramadan, monopolization was prevented, unfair competition conditions were abolished, all prices were reduced to appropriate figures and recorded in the narh book in a way that would be suitable for the purchasing power of the people.

In essence, the Narh book is a book that determines and processes product prices. But it means a lot.
