THIS guidebook is organized with intelligence and contains a wide assortment of information — on history, local customs and products, regional temperament, monuments and art, the Paris shopping district, and so on. The authors, with the Frenchman’s laudable respect for literature, are careful to inform you that here is the lake where Lamartine mourned Julie Charles, there are the woods which Victor Hugo trod, this is the claret beloved of Voltaire. Pierre Andrieu, noted gastronome, contributes essays on the special dishes and the wines of each region. The book is sumptuously illustrated with three hundred full-color sketches, a hundred old prints, and a score of iconographic maps which could not be better. The translation, alas, could hardly be worse.
