(Chris Yunker)A month after more than 900 authors signed a letter sent to Amazon CEO Jeff Bezos asking him to resolve his company’s ongoing contract dispute with book publisher Hachette, an even larger group of writers has written to Bezos and members of the Amazon board of directors to explain how this standoff has hurt authors. For those coming to this story late, Amazon and Hachette Book Group, one of the nation’s largest publishers, have been unable to agree on wholesale pricing terms, most notably on e-books. Amazon is attempting to pressure Hachette into making a deal by refusing to take pre-orders on new Hachette titles.
