The dictionary is the best book to have.Me too! I've got a library quality edition of the big Websters on a stand in my den. It gets used regularly. And many people in my family and among my friends have discovered the pleasures of browsing through it when they're here.
A dictionary was one of my favorite books when I was very young. Webster's or the OED is always an intellectual oasis for me, along with Roget's Thesaurus, Rodale's Synonym Finder, the big National Geographic World Atlas, and the most recent edition of the CIA's The World Fact Book. Noble tools all of them. Right up there with firemans' helmets.
It contains all the other books.
