great satisfaction that he had “modernized the punctuation by deleting thousands of commas and dashes, and probably should have deleted hundreds more.” He was confident that he had “given the book a more coherent plan than Mark Twain’s” and he was unapologetic about having “left out” what seemed to him “uninteresting.” 8 Neider, too, was unhappy with Paine’s acceptance of Mark Twain’s plan to publish the autobiography “not in chronological order but in the sequence in which it was written and dictated. What an extraordinary idea! As though the stream of composition time were in some mysterious way more revealing than that of autobiographical time!” 9 Neider had permission from the Mark Twain Estate to combine some thirty thousand words from the unpublished dictations with what Paine and DeVoto had already published. Like DeVoto, he omitted what he disliked, and was also obliged to exclude portions that Clara Clemens Samossoud (Clemens’s daughter, by then in her eighties) disapproved of publishing. He then (figuratively) cut apart and rearranged the texts he had selected so that they approximated a conventional, chronological narrative—exactly the kind of autobiography Mark Twain had rejected. The result of these several editorial plans has been that no text of the Autobiography so far published is even remotely complete, much less completely authorial. It is therefore the goal of the present edition to publish the complete text as nearly as possible in the way Mark Twain intended it to be published after his death. That goal has only recently become attainable, for the simple reason that no one knew which parts of the great mass of autobiographical manuscripts and typescripts Mark Twain intended to include. In fact, the assumption had longprevailed that Mark Twain did not decide what to put in and what to leave out—that he left the enormous and very complicated manuscript incomplete and unfinished. That assumption was wrong. Although Mark Twain left no specific instructions (not even documentation for the instructions that Paine professed to follow), hidden within the approximately ten file feet of autobiographical documents are more than enough clues to show that he had in fact decided on the final form of the Autobiography , and which of the preliminary experiments were to be included and which omitted. This newly discovered and unexpected insight into his intentions is itself a story worth telling, and it is told for the first time in this introduction. Three printed volumes are planned for this edition, which will also be published in full at Mark Twain Project Online ( MTPO ). Exhaustive documentation of all textual decisions will only be published online. 10 This first volume begins with the extant manuscripts and dictations that must now be regarded as Clemens’s preliminary efforts to write the autobiography and that he reviewed and rejected (but did not destroy) in June 1906. They are arranged arbitrarily in the order of their date of composition, solely because Clemens himself never specified any order. Some of these texts he explicitly labeled “autobiography,” and some are judged to be part of his early experiments on other grounds, always explained in the brief headnotes that introduce them. We include those preliminary texts for which the evidence is reasonably strong, without asserting that there were no others. The Autobiography of Mark Twain proper begins on p. 201 in this volume, starting with the several prefaces Clemens created in June 1906 to frame the early manuscripts and dictations he had selected as opening texts, followed by his almost daily Autobiographical Dictations from 9 January through the end of March 1906—all that will fit into this volume. The dictations are arranged in the chronological order of their creation because that is how Clemens instructed his editors to publish them. The remaining volumes in this edition will include all the dictations he
