For Italian, I would recommend "The Frugal Gourmet Cooks Italian" by the late Jeff Smith. Wonderful book - four hundred something authentic and old world recipes all adapted for the American kitchen, history & cooking techniques. I've been using my copy since it was first released about 20 years ago now. I'm pretty sure it's long since out of print, so, if you buy, I would recommend the hardcover version, over the paperback, as the paperbacks are probably falling apart at this point.

Seafood is pretty varied, do you have a particular country style you might be interested in or are you just looking for something that hits recipes from many geographic regions and cultures?
