Fan Letters, Then and Now
In his fan mail upon the publication of Leaves of Grass in 1855, Walt Whitman received a gushing letter from one Ralph Waldo Emerson, who knew a thing or two about writing himself. He told Whitman that his new book "meets the demand I am always making of what seemed the sterile & stingy nature, as if too much handiwork or too much lymph in the temperament were making our western wits fat & mean....I greet you at the beginning of a great career, which yet must have had a long foreground somewhere, for such a start."
Just in case your college copy of Leaves has grown a bit dog-eared over the years, Penguin Classics has rushed in with a 150th anniversary edition, together with an introduction Whitman couldn't have procured even in his best years. It's by the omnipresent Harold Bloom.
