This information definitely would have helped me doing some research for college papers and will help me researching now!
Her first point about the keyword "cookery" is very true even if it seems a little odd.
Go get one of your cookbooks and look at the copyright page-- look all the way at the bottom of the page where the book is classified and... ta-da!:
Usually listed first then further classified into a regional cuisine (many of my cookbooks say "Cookery, French"). Even some of your favorite food memoirs will have Cookery listed-- definitely the place to start!!
