Tech book publisher John Wiley & Sons says Apple has removed all of its titles from the company’s retails stores in retaliation for an upcoming biography of Apple CEO Steve Jobs. The author of “iCon Steve Jobs: The Greatest Second Act in the History of Business,” Jeffrey S. Young, said Wiley’s books disappeared from Apple Stores last week after “a month of increasingly contentious discussions about publication of the book,” according to the Mercury News. “It became increasingly clear that Apple was not happy with the publication of the book,” Wiley executive Kitt Allan said Monday. “Recently, the meaning of that became clear when Apple told us that our technology books were immediately being pulled from their Apple retail stores. But, of course, Wiley stands behind our authors.”
