Here, for the first time, is a volume that gathers the published verse of Allen Ginsberg in its entirety, a half century of brilliant work from one of America's great poets. As the chief figure among the Beats, Ginsberg changed the course of American poetry, liberating it from closed academic forms with the creation of open, vocal, spontaneous, and energetic postmodern verse. Ginsberg's raw tones and attitudes of spiritual liberation also helped catalyze a psychological revolution that has become a permanent part of our cultural heritage, profoundly influencing not only poetry, popular song, and speech but also our view of the world.
