Add every topic in the Bible into a 2nd contents list, more detailed than the 1st traditional list of bookpart names, which seem less descriptive to most.

Edit: I was recently given the New World translation (Study edition) by a Jehova’s Witness. It contains this updated contents list!

Advantages from a 2nd contents list: Faster grasp the whole “story” continuum. Select topics easier. Learn faster. Get less confused about whatever the book is about. And whatever other Advantages.

Disadvantages: more paper and more ink required. Somebodies need to do the topic work and printing and publishing. Many people need to Wonder how this wasn’t outvented centuries ago.

Example, translated from a Finnish Lutheran official Bible:

23. The book of Isaiah

23.1.The 1st part (condense into topic descriptive later)

23.1.1.Predictions about Judah

23.1.2.God reproaches God’s people

23.1.3.The coming time of peace

23.1.4.God’s day

23.1.5.Chaos in Jerusalem

23.1.6.God operates justice

23.1.7.Warning to Jerusalem’s flamboyant women

23.1.8.Zion’s salvation

23.1.9.Song from a vineyard

23.1.10.Oh yous!

23.1.11.God’s hate

23.1.12.A faraway people arrives into punishers

etc.

A 3rd, more detailed list of contents is also possible, and then probably the 4th list is the Bible’s whole translation in full as it has been till now.

Any valuable, worthy, curiosity pulling book can be clarified the same way.

I recommend using numbered topics as exemplified here, in the style of Ludwig Wittgenstein’s Tractatus.

Add page numbers also.
