Harvard Law Library Executive Files Brief Backing OpenAI on Fair Use in Training

leppert · x · 2026-11-03

Gregory Leppert, in his personal capacity, has filed an amicus brief with the U.S. District Court for the Southern District of New York, siding with defendant OpenAI in In re OpenAI copyright litigation. He currently serves as Executive Director of the Institutional Data Initiative (IDI) at Harvard Law School Library, an organization jointly funded by Jane Street, Meta, Microsoft, and OpenAI, among others.

Core argument: AI systems will play a key role in the next era of libraries' mission as stewards of information; if the court rules that AI training does not constitute fair use, it would severely limit libraries' capacity for digitization and open access to knowledge. He also cites the Caselaw Access Project he previously led—which digitized and opened up 360 years of U.S. case law—as supporting precedent.
