The prosecution has next called Tracy Menzies, a senior vice president at HarperCollins.
She is testifying about Donald Trump and Bill Zanker's 2007 book, "Think Big: Make It Happen in Business and Life."
Trump, at the defense table, tilted his head up at the large screen at the front of the courtroom and then leaned toward his monitor at the defense table as his image appeared on the cover jacket for the book.
Menzies testified about passages from the book, quoting Trump's approach to business and people management.
"As a matter of fact, I value loyalty above everything else -- more than brains, more than drive, more than energy," Trump wrote in one portion of the book, read aloud by Menzies. Another portion of the book noted that loyalty has become "part of the corporate culture of the Trump Organization."
"My motto is: Always get even. When somebody screws you, screw them back in spades," read another quote.
"When you are wronged, go after those people because it is a good feeling and because other people will see you doing it."
Also: "Get the best people and don't trust them."
