Query: Wrong publication year.

The pub. year 2003, cited by Amazon, is wrong (I've submitted a correction). The dictionary was published first in hardcover in Germany in 1989. This unrevised paperback edition was issued for the U.S. market in 2005. If you can do without updates to the vocabulary reflecting changes for the last 15 or so years, it's still a fine dictionary. Otherwise, wait for the new edition which is actually in preparation, according to the publisher.
