"I highly recommend it to anyone seeking a comprehensive, lucid, lively, and extremely readable account of regional variation in German or the German research tradition in this field." Language "...by far the most comprehensive text available in the field....The text will benefit a diverse audience. For instructors and researchers interested in the German language, the book is a must, since it presents important information nowhere else available in such a concise, up-to-date, and generally well-organized manner. For the sociolinguist, the book presents one of the few successful attempts to apply the tradition of sociolinguistics to a single language system." Helga H. DeLisle, Polylingua "...an excellent example of a way to extend the boundaries of what is considered relevant and significant for language study." Mary E. Wildner-Bassett, The Modern Language Journal "...bring[ s] a valuable multidimensional approach on a diachronic palette to the study of linguistic variation in German....I rather expect that Barbour and Stevenson will establish themselves as a regular entry on many graduate program reading lists."
