Yes I agree that is not canonical book. Although it is a great compilation for what I read in the introduction, because it includes the suttas following the gradual talk.
This is the kind of book that I was suggesting in my previous post.

I’m very happy that someone put it together centuries ago and would be great to have easy access to that compilation in English with a table as Bhante @sarana suggested or in some other form. That’s why I’m asking if this is already available.
