The American Heritage Dictionary of the English Language, Third Edition

The third edition of the American Heritage Dictionary is a beauty--2,134 pages and 8.5 pounds--containing a lexicon of more than 200,000 entries, plus an appendix of Indo-European roots for etymology enthusiasts. The crisp white pages and sharp black print are easy on the eyes, the drawings and pictures (nearly 4,000 in all) are a delight, and along with the lucid, erudite definitions are 4,000-plus quoted illustrations of usage from the likes of Shakespeare, Melville, and Updike. Though it's the chosen reference of editors, it's more than a mere tool of the trade--it's a luxurious linguistic experience.
