Largely what Tim said.
This is a very core list of the good books for the hard core collector.
I was looking at a fitting recently trying to kantei it to a specific maker, though it is mumei.
There is one 99.95% authoritative book in this area, and it took me about 15 years to buy a copy.
I may only use the book 1 or 2 times per year, but it is the binary [yes/no] book to have for kantei in that particular area.
That is all I will say for now.
After about 30 years, I've been able to narrow it down to about 20 books. 10 of those books are"must have or stay ignorant" tomes of knowledge.
