I haven't read either, but the november issue of Saveur had a review of " Lost Recipes" by Marion Cunningham. The gist was that the book takes recipes from the 50's, some true to the era (using canned soup, dry milk, etc) and some with a few added touches. They go on to say that some of the recipes were excellent, but others were not- my favorite quote in the review was "I may be able to go home again, but would I want to eat everything I found there?". Most books, cookbooks and otherwise, seem to be hit or miss based on personal preferences, but what concerned me the most was the comments that some of the recipes were sloppy- some recipes omitted baking temperatures; one started with instructions for a vinaigrette that was never mentioned again; one called for a 8x3 casserole dish.
Please remember, I have not read this book, so I cannot give you my personal bias. I also don't know how good/poor Saveur reviews are on average (this was my first issue). I hope I helped a little.
