I really liked the older version of this book, but now they have revised and expanded it, A korean mother's cooking notes.
I really also liked Copeland mark's book, and Korean cooking by Judy huhn, and growing up in a korean kitchen by hepinstall.
Also Cooking Korean Food by maangchi. She has her own website with recipes, Cooking Korean food with Maangchi
no cookbook, in paper form but Aeris from Aeriskitchen has recipes on her site and a kindle version which I have no checked out.
