Do they sell Cookbooks anymore?

I upgraded plumdumpling's answer because, well, "How to cook everything" is what I had in mind when I clicked on your question. My wife's grandmother was a whiz-bang cook and had newspaper articles featuring her recipes. I transcribed the recipes, and it became clear that cooking changed in the 1950s when Campbells began featuring recipes using soups as a base. That thinking prevailed until frozen dinners became a big factor. And now meal kits are causing a further disruption. I'm not totally opposed to using prepared ingredients in cooking, but I try to limit it to the same importance as beef or chicken broth.

Of course you can buy cookbooks at a bookstore or online. 

Sure they sell cookbooks. 

Many cookbooks written in the 50's and 60's used "convivence" ingredients that made the "housewives" jobs easier since many were in the work force. 

Take your recipes that use cans of cream of whatever soup and make a white sauce base yourself then carry on with the recipe as written.  Easy to make it a mushroom, celery, onion, broccoli or any other sauce. 

Other packages ingredients like the dry soup mixes are mostly salt, beef or chicken base and dehydrated onions and you can do much better than that. 

Your cook or bake time might have to be adjusted as well as liquid amounts if you are going to use "real" rice in place of "instant" rice.

Box cake mixes can be replaced with a real cake recipe that you can find in a simple search on the web. 

Dream Whip (although you can still find it) can be replaced with real whipped cream or a frozen non dairy whipped topping. 

Tons of printed cookbooks out there. I collect them & have over 100...while you can find them anywhere, I get the best deals at Ollies

of course they do. Step into a book store and browse the cook book section.

Yes. There are about a million on sale right now. Google cook books

Bookstores have entire sections devoted to cookbooks.

Yes, they sell a lot of cookbooks and many of them have everything from scratch. You must not have been in a bookstore lately. Try Joy of Cooking.  Or Mark Bittman's How to Cook Everything.

Cookbooks sell So well that they may well be keeping places like Barnes and Noble open. Digital cookbooks are not what most cooks want. 

Two words Fannie Farmer - excellent cookbook and tried and true recipes.
