What Constitues a Good Cookbook?

[Marilyn]

This is the criteria I would use, what would you say constitutes a good cookbook?

Good recipes with readily available ingredients.
Recipes that are original.
Cookbooks can and should be written with a sense of humor.
Information about the history of the recipe should be included.
Nutritional Information should always be included.
Cookbooks should bind the author and reader together so bits of personal history would be a nice inclusion.
Minimum use of equipment not found in most homes.
