"A Book of Prefaces" by H. L. Mencken is a collection of essays published in 1917. This provocative work attacks American culture, literary movements, and Puritan influences on American letters. Mencken devotes essays to Theodore Dreiser, Joseph Conrad, and James Gibbons Huneker before unleashing his most controversial piece on Puritanism as a stifling literary force. The book sparked outrage among academics and defenders of American culture, yet inspired future writers like Richard Wright and marked a turning point in Mencken's career as America's most fearless cultural critic.
