Named as plaintiffs in the complaint are publishers Hachette, Macmillan, McGraw Hill, Elsevier, and Cengage, with the case brought before a federal court in Manhattan. According to the suit, the company's engineers obtained pirated books and journal articles by routing through Anna's Archive — a search engine that indexes piracy repositories such as LibGen and Sci-Hub — to acquire unlicensed copies for use in training. The complaint further accuses Zuckerberg of direct involvement, alleging he "personally authorized and actively encouraged the infringement," The New York Times reported.
