What bothered me about this book,
is that there is never a source given. The author does not mention by which bot it was played, or in which game it was featured.
Even though I am somebody who on a daily basis plays with AI, reviews KataGo, Leela Zero, AlphaGo, Fine Art, and other bot games, it surprises me that most of these sequences in this book look rather unfamiliar.
I am sure that the content is not totally random, however I have not found any structure in it. They appear to be notes of a rather personal selection of joseki.
I would have hoped that this book would be structured more like a dictionary. And that is certainly not what it is.
