Originally published in 1958, this book forms the first part of a two-volume edition of Keats's letters, covering the period from 1814 to 1818. Several letters and papers not previously contained in English editions of the correspondence are included, and advances in the understanding of the dating and arrangement of the letters are reflected. Detailed editorial notes are provided throughout and biographical sketches of Keats's correspondents are also given. This book will be of value to anyone with an interest in Keats's letters and the development of Keats scholarship.
