A professor at the University of California, Los Angeles filed a class-action complaint against six major publishers, alleging that several of their policies violate antitrust law and impede academic research. The class-action lawsuit, filed Thursday in federal district court in New York, names Elsevier, Wolters Kluwer, Wiley, Sage Publications, Taylor & Francis, and Springer Nature as defendants. The publishers allegedly agreed to make peer reviewing an unpaid job, prevent academics from submitting manuscripts to more than one journal at a time, and bar them from freely sharing their findings during the lengthy peer review process.
