The Duden pictorial dictionary is a phenomenon. Instead of embracing the look-up-a-word style of conventional dictionaries, Duden allows you to browse by subject. If your topic is, say, the mechanical parts of an automobile, you turn to that page and you see an in-depth illustration with numbers, and on the bottom half of the page is a list with the word in German and English for what the number corresponds to. This book is indispensible for learning technical terms not found in most dictionaries, and includes many subjects...sports (even fencing), gambling, automotive, general knowledge, etc...anyone who is going to work for a German firm or wants to increase their vocabulary on an every-day basis should get this book....it is truly exceptional.
