Huh, I was going to suggest the ATK Family Baking Book, as it has many of my favorites, including molassas spice cookies, shortbread, peanut butter kisses, double chocolate, and a classic press sugar cookie.
I also like Sally's Baking Addiction though. I also like Love and Lemons. There are some good cookie recipes from Deb Perlman (on her site, Smitten Kitchen, and in some of her cookbooks).
My favorite chocolate chip cookie recipe is the Virginia Brown Butter Cookie recipe from this cookbook, contributed by my Criminal Law professor:
