Mark Twain Papers and Project

Preeminent center for the preservation of Twain’s writing, memory, and legacy

Mark Twain Papers

The Mark Twain Papers contain the voluminous private papers of Samuel Langhorne Clemens (Mark Twain). Before his death in 1910, Clemens passed these documents to his official biographer, Albert Bigelow Paine, who published sparingly from them until his death in 1937. Several successive editors served as literary executors for Clemens's estate and custodians of the Papers, which became part of The Bancroft Library in 1971.
