Mark Twain Project Online

"Mark Twain Project Online applies innovative technology to more than four decades' worth of archival research by expert editors at the Mark Twain Project. It offers unfettered, intuitive access to reliable texts, accurate and exhaustive notes, and the most recently discovered letters and documents. Its ultimate purpose is to produce a digital critical edition, fully annotated, of everything Mark Twain wrote. MTPO is a collaboration between the Mark Twain Papers and Project of The Bancroft Library, the California Digital Library, and the University of California Press"
