There are a couple of cookbooks that are in reasonably regular rotation here.
The best in some ways is one I bought just about 30 years ago "The I Never Cooked Before Cookbook". Lots of helpful hints and basic recipes and a couple of tasty ones.
I use my old Diet for a Small Planet and Recipes for a Small Planet books more than I use any of the cookbooks like Moosewood.
There are some good recipes in some of the old Time-Life collections. I particularly like the Russian, German, Scandinavian and the best one "The Cooking of Vienna's Empire".
I occasionally poke into one of my Frugal Gourmet cookbooks.
I'm going to pick up some of the Barefoot Contessa's cookbooks as they seem to have a lot of recipes that I'd actually use.
I rarely use pretty, illustrated cookbooks.
In the Time-Life books, I'm more likely to use a recipe from the little spiral-bound books than the large ones with the stories.
