The Martian

The Crown text is substantially revised from the self-published ebook: profanity reduced, spelling and grammatical errors corrected, scientific errors fixed, many minor stylistic changes, and a 263-word epilogue removed — so the 2014 first edition is not textually identical to the 2011 original, a point of interest to collectors. No book-club issue is documented. Later traps include the movie tie-in printings and the Deluxe Edition; the negative tell throughout is the absence of "First Edition" plus a number line ending in 1.
