Mr Trump's come-from-behind election win has left many Americans in shock, with commentators saying the property mogul and star of the reality show The Apprentice lacked the experience for the presidency compared to rival Hillary Clinton.
The Art of the Deal, ghostwritten by Tony Schwartz, is considered a business classic and has generated millions of dollars in royalties.
But in a New Yorker article in July, Mr Schwartz revealed he felt "a deep sense of remorse" about his contribution to making Mr Trump popular.
"I put lipstick on a pig," he said. "I genuinely believe that if Trump wins and gets the nuclear codes there is an excellent possibility it will lead to the end of civilization."
