Kerouac and Ginsberg, the two most celebrated members of the Beat Generaron, shared a profound friendship. Extraordinary in their scope, quality and intimacy, their letters were an active laboratory in which they ceaselessly shared and discussed their ideas, they recommended eachother books, analysed authors and literary movements, exchanged poems, and commented on drafts of their new works. This great correspondence not only reveals the creative processes of these two authors, but also serves as an incomparable portrait of two writers who headed the cultural and artistic movement that defined an entire generation.
