Henry David Thoreau's classic essay inspired Martin Luther King, Mohandas Karamchand Gandhi, and many other activists.

Few novels have had as profound an impact on American culture as On the Road. Pulsating with the rhythms of 1950s underground America, jazz, sex, illicit drugs, and the mystery and promise of the open road, Kerouac’s classic novel of freedom and longing defined what it meant to be “beat” and has inspired generations of writers, musicians, artists, poets, and seekers who cite their discovery of the book as the event that “set them free”.

This essay by Thoreau first published in 1849, argues that individuals should not permit governments to overrule their consciences. It goes on to say that individuals have a duty to avoid allowing the government to make them the agents of injustice. The quote: "That government is best which governs least," sometimes attributed to Thomas Jefferson or Thomas Paine, actually was first found in this essay. Thoreaus' thoughts were motivated by his disgust with slavery and the Mexican-American War but they are still relevant and resonate today.

Thoreau's classic account of the solitary life, describing his attempts to simplify his life and sort out his priorities by living alone in a cabin beside Walden Pond for nearly two years, is one of the most influential books ever written. The bible of the environmental movement, Walden vividly portrays Thoreau's reverence for nature, and his understanding of the idea that nature is made up of crucially interrelated parts.

First published in 1884, Mark Twain's Adventures of Huckleberry Finn is among the first novels in American literature to be written throughout in vernacular English. Some have called it the first Great American Novel, and the book has become required reading in many schools throughout the United States. The story is set along the Mississippi River in Missouri, Illinois, Kentucky and Arkansas around 1840. It depicts the development of Huckleberry (Huck) Finn, a boy about thirteen years old.
