This is a great deluxe, single-volume Encyclopedic Edition. A 1,946-page volume that is a complete quick-reference library. Encyclopedic Dictionary contains over 175,000 entries and over 2000illustrations. The 21st Century Webster's Comprehensive Dictionary contains thirty-two Encyclopedic Supplements, among Abbreviations, Grammar and Usage Handbook, The Library Research Paper, Greek and Latin Elements in English, Foreign Words and Phrases, Business Law, Business Math, Business Letter Writing, Glossary of Computer Terms, Word Processing Glossary, Spanish Glossary, German Glossary, Glossary of Biology Terms, Glossary of Physics Terms, Metrics Glossary, Tables of Weights and Measures, Medical Glossary, Biographies, Quotations Dictionary, Spelling Dictionary.
The definitions are not all up-to-date for the year this big volume was published (2003); Greece is mentioned as "a kingdom in SE Europe" which ceased to be with the referendum of 1974. However, the breadth (and depth!) of coverage of around 200,000 key terms is astounding. In retrospect, I wanted this book instead, but bought the Penguin Factfinder first, which is complementary to this one, but also not exactly what I wanted (I guess I wanted a single-volume lexicon/encyclopedia).
