These references would serve to aid you in setting priorities and identify your needs and gaps.
I don't understand. It seems to me that buying more books heads in the opposite direction of where I need to go unless I use it in a medical kit. Even then I need to consider space.
I recognize I have gaps in my plans and I am working through them.
How would that book aid me in setting priorities and identify my needs? I know what my needs are. I would even go so far as to say Hurricane Irma was a drill, a test to determine what I'm lacking. In looking again at the description of the book you recommended, I can see how it can address a couple of those things; $74.49 for a book in addition to what I have already bought and will need to buy, I have some reservations. I could look for a used copy.
