I haven't been baking much, but I have been reading. A friend recently went to Paris for a wedding, and I sent her with a short list of books to pick up. Among those related to baking was 100 % pain : La saga du pain enveloppée de 40 recettes croustillantes by Eric Kayser. I found it on amazon.fr because I wanted a French baking book, but looking through it, it is more amazing than I had hoped. I've just skimmed the beginning so far, but it has what looks to be a fairly thorough description of the history of bread and its cultural significance. I was just eager to get to the recipes.
