Never before published writings of the renowned author Mark Twain will soon be revealed by the University of California Berkeley's Bancroft Library.

The university's book publisher is set to release a comprehensive Twain's autobiography in November. When he died on April 21, 1910, he left strict instructions that his uncensored autobiography remain unpublished until 100 years after his death.

The university has announced it will publish Twain's autobiography "in its entirety and exactly as he left it." Volume I is slated for release in November. The remaining two volumes should appear within five years, said Alex Dahne, UC Press spokeswoman.

Never before seen photographs will also be included in the new book, a project the library has been working on for years.

The Motherlode Mark Twain Festival to be held Oct. 15-16 in Angels Camp, Calif., will kick off the celebration to one of the greatest figures in American literature.

Angels Camp is where Twain gathered material for his classic tale, "The Celebrated Jumping Frog of Calaveras County," a story that launched him to international fame.

The festival will include an uncensored look at the man, whose real name was Samuel Langhorne Clemens. Twain is perhaps best known for penning The Adventures of Tom Sawyer and Huckleberry Finn.

The event will also feature a new play about Clemens, titled "Sam and Laura."
