one of those "Which book should I read?" type questions: math.stackexchange.com/q/4269829/29335 I feel it is at best opinion-based. Honestly I feel like such questions try to use the site as a poll and aren't useful.

-∫ [Li₂(x²-1)]/(x²-1) dx from 0 to 1
Introduce summation and compose well.
We later arrive at Li₃(-¹/₄)
