Mary Rasenberger

US copyright lawyer and Chief Executive Officer of The Authors Guild, the United States' oldest and largest professional organisation for published writers. Rasenberger joined the Guild as its Executive Director on 3 November 2014 and the title was reclassified to Chief Executive Officer during her continuing tenure.

Her prior career, per the Authors Guild's October 2014 announcement, was as a "six-year Copyright Office and Library of Congress veteran" — federal copyright-policy practice that the Guild explicitly named as the qualification for the executive role.

Rasenberger is the named institutional spokesperson for the Authors Guild's writer-organising and strategic-litigation work on generative-AI training-data harms. On the 20 September 2023 class-action filing against OpenAI in the Southern District of New York (Authors Guild v. OpenAI Inc., No. 1:23-cv-08292), the Guild's announcement carries her named-CEO statement framing the suit as a stop-the-theft action — "it is imperative that we stop this theft in its tracks or we will destroy our incredible literary culture, which feeds many other creative industries in the U.S." — and her "identity theft on a grand scale" characterisation of the training-data harm to fiction authors. She is also the named lead Authors Guild participant on the Guild's 10 May 2024 ex parte meeting with the US Copyright Office (alongside Chief Legal Officer Kevin Amer and Director of Advocacy and Policy Umair Kazi) — the substantive policy-engagement track on AI-output labelling, attribution rights, and training-data licensing through the Copyright Office's 2023–2025 AI study.
