In the dictionary.

Okay people, let's talk about good dictionaries.  Comment or e-mail me.  I want to know what dictionary you recommend, and why.  I haven't bought a new dictionary in well over ten years, so I need to shop around.  Thanks.

UPDATE ONE:  No sooner do I post this, Grant Barrett comprehensively responds!  The man moves quickly.  However, no actual recommendations, just guidelines, so let me know your favorites.

I'm fond of The American Heritage Dictionary. Though it must be said that the only dictionary that matters in publishing is Merriam-Webster's Collegiate. Since I use that one on a daily basis, it's starting to win me over.

Webster's Third New International Unabridged. 450,000 entries of Americanese defined.

I love the copyeditor's best friend: Merriam Webster's Collegiate Dictionary, 11th edition.
