Concord Publications recently slightly changed (albeit for 1 title!) direction to publish a book on German U-Boats.

The new book (which is available now) is:

7071: U-Boat War 1939-45

Written by Ian Baxter, with illustrations by Studio Primots, the book follows the usual Concord format with 72 pages, 9 color plates and 172 contemporary photos.

From the company's description:

This volume traces the development of the U-boat as a strategic weapon in Germany’s arsenal. The book begins with a written description of the tactics employed and how their effectiveness ebbed and flowed as the war progressed. However, the backbone of this work is the many black-and-white photos of U-boats and their crewmen. These contemporary photos show German Navy submarines in port and at sea, as well as various details of their construction. The crewmen are also a focus of the photography, offering readers a study of their typical uniforms and appearance..

Fot those who requite it, for ordering purposes, the book carries the ISBN 962-361-175-7
