Wednesday, bestselling thriller writer Douglas Preston, who oversees the group Authors United, confirmed that the organization intends to contact the Department of Justice requesting an antitrust inquiry into Amazon's tactics.

Authors United formed to voice the concerns of authors whose sales have been hurt as a result of the stalled sales terms negotiations between Amazon and Hachette. The Financial Times reported the group's intention to request that the DoJ mount an antitrust investigation into Amazon's approach to its business, and Preston confirmed the move to PW.

According to Preston, a letter addressed to William Baer, assistant attorney general for antitrust, has been drawn up and calls for a closer look at Amazon's practices. News of the letter, said Preston, was leaked "very prematurely."

The pending letter to the DoJ is the third action taken by Authors United. In August, the gorup made its first move by running a signed full-page ad in the New York Times asking readers to write to Amazon head Jeff Bezos. Authors United is also, currently, in the midst of putting together its second project, which involves FedExing a letter to members of the Amazon board of directors which questions whether the board approves the policy of sanctioning books. The letter states: “These sanctions have driven down Hachette authors' sales at by at least 50 percent, and in some cases by as much as 90 percent.”
