- How to Read the Grid — What Does One Cell Count?One cell represents 'the number of stops a given route discusses within a given section.' It is not the weight of history, but the depth of the curriculum.
- S0・S1 — Pre-Coinage and Ancient CoinageS0 is a collection of short chapters, while S1 is dense with Greek routes. Both are source material for General History ①.
- S2 & S3 — World Empires and the Three Worlds of the Middle AgesS2 is empires, S3 is the three worlds and imported coins. In S3, the Japan route is the most substantial.
- S4 & S5 — The Globalization of Silver, and Banks and National BondsS4 is the thickest in the Section of Twelve. S5 is the Section of Banking and Paper, where No. 8 and No. 5 are located.
- S6 — The World of the Gold Standard, the Densest Modern SectionS6 is the thickest stage of the modern era. All eighteen routes are covered in S5–S8. General History ⑥ will be published next.
- S7 & S8 — War and Crisis, the Era of the DollarS7 is the stage of the system's collapse; S8 is the stage of the dollar. The prominence of the Korean route reflects the number of recoinages.
- S9・S10・S11 — From money without gold, to digital currencyS10 has few stops on its route; Issue No. 10 is central. S11 is a stage defined by terms, not by date.
