First, let me say that I got rid of 60 or 70 cookbooks last summer. There is only so much room on anybody's shelves and I was not using all of those.
However..
As an aside about cookbooks like this,I tend to keep either specialty cookbooks, or old cookbooks.
One of the reasons I love old cookbooks is not just for the recipes, but for the information they contain that you can't get in "new" cookbooks today.
Stuff like this--two pages from my 1965 Better Homes and Gardens New Cookbook....
As far as I've seen, you won't find stuff as politically incorrect as this in modern cookbooks. I once went looking for when cookbooks stopped putting the "whole animal and how it's cut up" in the cookbook. I think it was in the early 1970s, though that likely varied with the publisher.
It's kind of like the Foxfire books. If you want to know how to survive...if you need to know how to make a corn husk trough to filter lye for soap....you've gotta have somebody who knows to show you, or some kind of reference book to explain it.
I went looking for a cookbook with instructions on "How to cut up a frying chicken" once.
Nada.
Old cookbooks were the only ones with such information.
And my mom. I ended up having her come to my house for several sessions of "cut up the chicken and fry it" using her method.
People buy chickens already cut up now. If you need to cut up a chicken into the correct pieces to put a nice fried chicken dinner on the table, where you gonna learn?
Not from any modern cookbook, that's for certain.
How to render the fat from a hog you've slaughtered?
Yep, that's in old cookbooks.
