This is the best German dictionary by far that I have used in the past 30 years, it's truly outstanding.
New terms in this 5th edition: blog, civil union, first responder, identity theft, mujaheddin, picture messaging, reality TV, and rollover. This book is thumb-indexed to help you quickly find the word you're looking for.
There are two ISBNs, one for the version published in New York (ISBN 0060733810) and one for the version published in the U.K. (ISBN 0-00-712630-1).
My book has a different cover than the one pictured (it's red, white, blue and gold), and has 2108 pages, probably because it's the New York edition.
It covers the following material in this order:
Adjectives and Adverbs
General rules for forming the genitive
Pronunciation of German, of English, and of phonetic symbols
English to German dictionary
German to English dictionary
German strong verbs and conjugation
Numerals
Weights and measures
Time and date
The German spelling reform that became effective in mid-2005
