Amazon.com Inc. and a group of the country’s largest book publishers were hit with a second antitrust lawsuit in New York federal court Wednesday for allegedly conspiring to stamp out competition and raise the price of e-books.

The class action suit comes one month after the Seattle firm Hagens Berman Sobol Shapiro filed a similar complaint in the U.S. District Court for the Southern District of New York on behalf of consumers who said that Amazon and the publishers, known collectively as the “Big 5,” had agreed to price restraints that caused them to overpay for e-books purchased from retailers other than Amazon.
