Bread-Bakers v104.n034.9

I'm just back from a trip to Germany, where I ate some fabulous bread. I 
now want to try and make some of those whole-grain wild- yeast breads, such 
as Roggen-Vollkornbrot. Can anyone recommend a good book on German breads, 
or at least containing a good number of German bread formulas, in English 
or French (I don't speak German)?
