... I also have the Women's Day Encycolpedia of cooking set that I've have for 40 years...
I have that set too. I love it. I found 3 volumes at the local thrift store and fell in love them. So I set out on an eBay quest and after a few months found the whole set for something like $10.
Oh, and I donated the duplicate volumes back to the thrift store once I got my set.
