Following upon the print edition of Mark Twain Project's _Autobiography of Mark Twain, Volume 1_--published by the University of California Press and released for retail sale last week[1]--the book's Web edition has been released at Mark Twain Project Online (MTPO): http://bit.ly/automt1 As noted on MTPO's Recent Changes page,[2] only the TEI-encoded Web version contains the volume's substantial textual apparatus. All print content is included in the Web version. MTPO, launched in 2007, is produced by the Mark Twain Papers and Project of The Bancroft Library in collaboration with the University of California Press; the site is hosted by UC Berkeley's Library Systems Office and powered by the California Digital Library's eXtensible Text Framework.[3] During 2005–8 the CDL collaborated in MTPO's creation and initial development.
