If you want an overview of several low-carb plans, I recommend the book
The Low-Carb Bible by Elizabeth M. Ward
It includes information on several low and moderately-low carb plans - Atkins, Carbohydrate Addicts, Neanderthin, Protein Power, Schwarzbein Principle, South Beach, Sugar Busters, Suzanne Somers, and the Zone.
I would recommend ordering it from your library or through amazon.com (used, you should be able to get it for $1 or so - with shipping under $6.00).
It's a great book, but it's not a substitute for any of the plan's books. If a plan sounds interesting, you'd really want to get the program's book. I wouldn't recommend doing Atkins, South Beach, the Zone - or any of the diets without their book.
