I knew of a few back when Atkins was all the rage. Since I haven't seen them recently, I'm going to assume they are out of print. There are a few great e-zines though. The ones I subscribe to are Low Carb Luxury and CarbWire. Also, check the checkout lanes at grocery stores and megamarts....they always have those little cookbooks and very often they are low carb ones. I saw a low carb summer cooking one recently.
Also, there are quite a few really great low carb cookbooks available. Check out the bargain section at Barnes and Noble for a great deal, or check them out from the library for free. I often check out cookbooks and photocopy the recipes that I want to try but won't get around to making before the book needs to get returned. It's much, much cheaper and easier to store a binder full of recipes that I really want to try rather than a stack of cookbooks.
