What makes you so sure that it's public domain? Of course the published forms that Mark Twain and his friends published should be public domain, but these seem to have been released in installments and other incomplete snippets. The full, raw manuscript, which seems to be what's requested, would naturally contain portions which were never published. Given that such a collection in its entirety would be a pseudonymous, unpublished work, the entire manuscript won't be in the public domain until 2031. http://copyright.cornell.edu/resources/publicdomain.cfm http://copyright.cornell.edu/resources/publicdomain.cfm http://www.law.cornell.edu/uscode/html/uscode17/usc_sec_17_00000303----000-.html http://www.law.cornell.edu/uscode/html/uscode17/usc_sec_17_0... http://www.law.cornell.edu/uscode/html/uscode17/usc_sec_17_00000302----000-.html http://www.law.cornell.edu/uscode/html/uscode17/usc_sec_17_0...
