NEW YORK - With O.J. Simpson in jail on charges of robbery and other felonies, the best-selling book about his alleged murder confession is getting a second printing.

Beaufort Books has commissioned an additional 50,000 copies of Simpson's "If I Did It," the ghostwritten account of how the ex-football star would have murdered Nicole Brown Simpson and Ronald Goldman. The book, which came out last week and on Tuesday ranked No. 2 on Amazon.com and Barnes & Noble.com, now has 200,000 copies in print.

"The arrest brought the whole question of O.J. and the law back into everybody's consciousness," Beaufort owner Eric Kampmann told The Associated Press.

Simpson, accused of leading an armed heist of his sports memorabilia at a Las Vegas hotel, was booked Sunday on six felonies, including two counts of robbery with use of a deadly weapon. If convicted, he could get up to 30 years in state prison on each robbery count alone.

Simpson has said that he was only reclaiming possessions that had been stolen. Arraignment was set for Wednesday.

"If I Did It" was supposed to be released last November by ReganBooks, an imprint of HarperCollins. But the book was soon pulled in response to public outrage and a federal bankruptcy judge later awarded rights to Goldman's family to help satisfy a $38 million wrongful death judgment against Simpson, who had previously been acquitted of murder charges.

After signing up with Beaufort, a much smaller publisher than HarperCollins, the Goldmans retitled the book "If I Did It: Confessions of the Killer" and commentary was added from ghostwriter Pablo Fenjves and author-journalist Dominick Dunne, who covered the Simpson trial for Vanity Fair.
