This decision reinforces the idea that copying for non-commercial, transformative purposes—like making a book searchable, training an AI, or preserving web pages—can be lawful under fair use. That legal protection is essential to modern librarianship.
I'm happy that this works out in libraries' favor, but I can't see how Anthropic managed to slip through "copying for non-commercial, transformative purposes". Are they a non-profit and I just didn't know?
