‘“Covered Book” shall mean any in-copyright book or portion thereof, whether in existence as of the date hereof or later created, in which any Plaintiff (or any subsidiary or corporate affiliate of a Plaintiff) (a) owns or controls an exclusive right under the Copyright Act …’
‘the “Internet Archive Parties” … are permanently enjoined and restrained from engaging in any of the following acts in, from or to the United States … the distribution to the public, public display, and/or public performance, of Covered Books in, from or to the United States in Case 1:20-cv-04160-JGK-OTW Document 214-1 Filed 08/11/23 Page 3 of 6 any digital or electronic form, including without limitation on the Internet Archive website (collectively “Unauthorized Distribution”)’
