Alfred A. Knopf the publisher of “Mastering the Art of French Cooking,” by Julia Child has released the book in eBook format after technology caught up and was able to duplicate the unique two-column layout, allowing the reader to see the ingredients alongside the recipe, among other things. It is best read on tablets rather than eBook readers due too the intricacies of the layout. Cookbooks have a long future in print, but due to advances in technology you probably will see more cookery books in eBook format.
