The historical background chapter satisfied my curiosity about German origins, but also explained why Norwegian has so many Tysk cognates. Dialectology is not an area that I had explored before, such as the concept of 'isoglosses', which are geographical boundaries separating regions with different speech characteristics. Apparently the patterns for rolling the 'r', with the front trill being replaced by a back of the throat sound, are spreading simultaneously across multiple languages. The isogloss chart for these shows how this characteristic tends to be separated on a north south basis both in the French and German speaking regions. (If you are concerned that my lay explanation isn't technical enough, rest assured that this book also uses terminology such as 'voiceless lenis obstruents'-there should be no worry that college students will be ruined by reading a book that is too easy.)

The authors also wrote on urban speech patterns, a subject area they feel has been inadequately addressed by studies of German, and on class differences. I continue to be mesmerized by Swiss diglossia, and I appreciated a chart mapping out the Swiss pattern of dialect and Hochdeutsch use according to social context. (Incidentally, class differences in Swiss German are minimal in comparison to Austria and Germany.)

Switzerland, Italy, France, Luxemburg, and Belgium all have transition areas where German rubs against one or more languages, and the result of this is different in each area. The authors analyze the linguistic changes ongoing in these border regions, including the northern parts of Germany, where Danish and Frisian are disappearing.

Each chapter ends with a 'Further Reading' section that recommends classic and other relevant texts. The book concludes with a short glossary, containing both English and German terminology, and a lengthy bibliography of both German and English sources.

Certainly this book is most appealing to those who are interested specifically in the German language. However, outside of a one short section, a knowledge of German is not expected, nor is a background in either linguistics or sociology. I expect most of the readers to be German-speakers, but the book would also be useful to those who are just interested in the social issues of language, or are doing research in the subject.

Instead of doing a broad-brush introduction to Socio-Linguistics, the authors chose to introduce the concept by focusing on a single language, an approach that I found very successful and accessible.
