We considered a list of the best American books. Here are five that may help accurately show the national character. Most from a century or so ago, they still entertain, teach, and inspire:

Moby-Dick by Herman Melville

First published in 1851, the adventure stories of Captain Ahab and his monomaniacal(偏执的) pursuit of the white whale draw us into a universe full of fascinating characters and stories.

Leaves of Grass by Walt Whitman

Poems by Emily Dickinson

An enthusiastic poet whose works have had considerable influence on modern poetry, Dickson’s frequent use of dashes, occasional capitalization(大写) of nouns, and unconventional metaphors(隐喻) have contributed to her reputation as one of the most inventive poets of the 19th century American literature. However, most of her poems were not published during her lifetime.
