Much to my dismay, I learned that the Betty Crocker coos books change over the years.
I had a 1961 edition - and the cover fell apart - so I tossed it, thinking it would be no big deal to replace it. WRONG!
If you have an edition that you love, hang on to it, even if it is falling apart.
Copy the recipes you use and care about and put them in a recipe card box or a notebook if your book is coming apart.
I, too, like to have a few recipes that start "from scratch."
