Talk about being quick on the buzzer. As former Jeopardy champs Brad Rutter and Ken Jennings face-off against the computer named Watson once again tonight, there is already an e-book available about the television contest, which pits human knowledge against the IBM super-computer. Final Jeopardy: Man vs. Machine and the Quest to Know Everything, by Stephen Baker, will be released as an e-book this evening, even before the conclusion of the three-day match on Feb. 16.

From Jacket Copy:

When … the match is over, the book will be finished. People who’ve purchased the e-book already will get an update with the last of the material that tells the story of the showdown. New e-book buyers will get the whole thing.

And publisher Houghton Mifflin Harcourt says the hardcover version of the book, with the new material about the match, will follow very soon.
