Bancroft Library undertook to produce a complete autobiography of Twain, based upon material within their collection. The stated goal is "to publish the complete text as nearly as possible in the way Mark Twain intended it to be published after his death.". This was published in three-volumes between 2010 and 2015, with the first in the 100th anniversary year of Twain's death. All three volumes are available online with introductions and historical annotation from the editors also included with the text. The head editor for this work was Harriet Elinor Smith. The first volume of a three-volume edition runs to 760 pages. It includes introductory material explaining how Twain's autobiography was written. Then follows Twain's early, fragmentary attempts at writing it; and the text of his autobiographical dictations (the main series), beginning on 10 January 1906. Volume 1 collects these up until 30 March 1906. Volume 2 was published in October 2013 and runs to 736 pages. This collects dictations from 2 April 1906 until 28 February 1907. The third and final volume of the Mark Twain Project edition was published in October 2015. It contains 792 pages with entries dated from 1 March 1907 to 21 October 1909. Twain's autobiography closes with a piece written in December 1909 where he laments the death of his daughter Jean and declares that, with her, his motivation for writing the autobiography has died. Suffixing the third volume is the 429-page "Ashcroft-Lyon Manuscript" written in 1909. In this Twain attacks his secretary, Isabel Lyon, and business manager, Ralph Ashcroft, for alleged embezzlement of money from the author and for manipulation of Twain's relationship with Jean, much to her distress. It takes the form of a letter to William Dean Howells, though it was never sent nor intended to be so. It was not intended by Twain to include this as part of his autobiography, and it had never been published prior to 2015 — though it had been available to scholars as part of his papers. The 21st-century editors considered it sufficiently important to include within this publication. Copyright status The version published in 2010, representing Twain's attempts from 1906 and earlier, would have entered the public domain by under ordinary circumstances. The state of the law at the time of his death notwithstanding, the 1976 revision provided that unpublished works created before January 1, 1978 would have entered the public domain by
