Welcome, Matt! (really, I guess, welcome *back*...)
With you on the America's Test Kitchen/Cooks' Illustrated practice of >> repackaging content in a million different ways (then again, EYB helps me figure out what recipes I have where, so maybe I won't end up buying the same recipes 4 different times). <<
In the several years before I really began to use EYB to the fullest, I routinely bought Cooks' Illustrated special issues in addition to the bi-monthly magazine. Then a year ago or so I indexed one of the special issues for this site, and whoa! All but one of the recipes had appeared in the magazine not long before, some in several issues. Haven't bought any of the CI/ATK output for a good while, but the collection I have is many, many times more useful to me because of Eat Your Books.
As is my shelf of cookbooks, which grew quite a bit due to notes and comments from EYB members, and from looking at other members' Bookshelves (fair warning!) The fever has broken a bit, and I'm down to only six cookbooks from which I haven't cooked at all (new and effective rule: can't buy a new cookbook until I've cooked from all I have). The bookmarking function is an excellent way to keep track of wishlists in various categories, and of recipes that I've made, ones I'm most eager to try, and ones that use particular ingredients.
The years I spent in Iowa in the mid-1980s were some of the best of my life; now determined to track down Little Heathens on your recommendation. And Wolfert's clay pot cookbook has just moved a little higher on the wishlist...
Hope to hear much more from you as you cook your way through that solar-system-long list!
