Katherine Klosek, director of Information Policy and Federal Relations at the Association of Research Libraries, and Samantha Teremi, the Licensing Librarian at UC Berkeley Library, examine how today’s contractual restrictions on AI echo the same concerns libraries raised 20 years ago during the US Copyright Office Digital Millennium Copyright Act (DMCA) Section 104 study. This aligns with Library Copyright Alliance principles on AI and copyright, which hold that the existing US Copyright Act, as applied and interpreted by the Copyright Office and the courts, is fully capable at this time of addressing the intersection of copyright and AI without amendment.
