I don't have Hamelman, don't have Dan Leader's first book, don't have Calvel's book, don't have Bernard Clayton's, don't have Maggie Glezer, etc., etc... 

I am interested mainly in natural yeast sourdoughs.  I especially like recipes that use all starter and no commercial yeast though am not closed minded about that.  I generally don't bake much that's a straight dough recipe, so if a book is full of just those, it won't get used much.  I would also like to get better at rye breads, and breads with more rye content.  Whole grain and healthful is a bonus.

Also I saw reference to a book called Celebration Breads, does anyone have it, is it good?

I'm wondering about the Laurel's Kitchen one, as people often speak of it highly, will it be "advanced" enough or have good new information for me?

Or any other books I haven't thought of?
