I have some of the WW cookbooks. My favorites are Slow Good, Take Out Tonight, Take 5 and Around the World. I also buy the WW magazine and subsribe to the WW site's newsletter.
Other good recipe sources for me are:
Cooking Light Magazine
Vegetarian Times Magazine
Organic Style Magazine
Eat to Fight Diabetes Magazine (published by Prevention Magazine 2 or 3 times/year)
The South Beach Diet cook books
Suzanne Sommers cookbooks
