The Cambridge Grammar of the English Language by Rodney Huddleston, Apr 15 2002. I haven't read it so I don't know if it's the exemplar of my search, but at least I found a possibility.
Yet the problem persists: how do you learn more about such books and such topics?
Cons: 1. So I worry that on average, CGEL's topics may emerge too abstract or esoteric.
2. At 1860 pages, reading it may prove onerous or stark, though I never intended to read a grammar book in one continuous instance.
