Mark Twain's classic works are considered too politically incorrect for today's readers.
Revised versions of "The Adventures of Huckleberry Finn" and "Tom Sawyer" will be published to better suit changing times.
The "N" word appears 219 times in Huckleberry Finn, and four times in Tom Sawyer.
The new editions will replace the offensive word with "slave."
Critics of the changes say Mark Twain's language represents America's past, and that the revisions are untrue to the time period.
