Thoroughly annotated and indexed, they are supplemented by genealogical charts of the Clemens and Langdon families, a transcription of the journals Clemens kept during his 1872 visit to England, book contracts, his preface to the English edition of "The Gilded Age", contemporary photographs of family and friends, and a gathering of all newly discovered letters written between 1865 and 1871. This volume is the fifth in the only complete edition of Mark Twain's letters ever attempted, and the twenty-fourth in the comprehensive edition known as "The Mark Twain Papers" and "Works of Mark Twain".
