New York, Nov 23 A literary spoof of ex US Vice Presidential candidate Sarah Palin's book, 'Going Rogue: An American Life', has created much confusion in the market.

And the chaos has led the publishers of the original book to take out ads to direct buyers for the official version.

The rival book, 'Going Rouge: An American Nightmare', was released on the same day as Palin's memoir and features an almost identical cover.

The book was compiled by Nation magazine staffers Betsy Reed and Richard Kim and was published by HarperCollins.

"We have been contacted by numerous media outlets across the country asking for interviews with Sarah Palin, or companies offering security for her while on tour," the New York Post quoted Colin Robinson, co-publisher of the book, as saying.

"One Web site not only thought we were Ms. Palin's publishers but called the book 'Going Rough.'

"We've noticed that someone, presumably HarperCollins, has been buying ads on Google redirecting people looking for 'Going Rouge' to 'Going Rogue,' which seems very unsporting of them," he added.

And the confusion between the books has even struck CNN's Political Ticker, which quoted Obama adviser David Axelrod saying he'd be borrowing Obama campaign manager David Plouffe's copy of 'Going Rouge'.

USA Today's section The Oval wrongly posted the cover of 'Going Rouge' with a review of Palin's book.

It has since corrected the confusion with the statement: Erratum: An earlier posting featured the photo of a different Sarah Palin book. The Oval regrets the error."

Last week, Fox News Channel apologized for showing the cover of the takedown book while discussing Palin's memoir.

"We are sure that many people who mistakenly bought our book will have been pleasantly surprised. You learn more about the real Palin in our version," added Robinson. (ANI)
