  "To summarize the analysis that now follows, the use of the books at issue to train Claude
  and its precursors was exceedingly transformative and was a fair use under Section 107 of the
  Copyright Act. And, the digitization of the books purchased in print form by Anthropic was. 
  also a fair use but not for the same reason as applies to the training copies. Instead, it was a
  fair use because all Anthropic did was replace the print copies it had purchased for its central
  library with more convenient space-saving and searchable digital copies for its central
  library — without adding new copies, creating new works, or redistributing existing copies.
  However, Anthropic had no entitlement to use pirated copies for its central library. Creating a
  permanent, general-purpose library was not itself a fair use excusing Anthropic’s piracy."

  "Because the legal issues differ between the *library copies* Anthropic purchased and
  pirated, this order takes them in turn."
