Project: Caselaw Access Project

Where can I find Caselaw Access Project?

What does Caselaw Access Project do?

The Caselaw Access Project offers free, public access to over 6.5 million decisions published by state and federal courts throughout U.S. history.

Why does Caselaw Access Project exist?

Access to our common law - the written decisions issued by our state and federal courts - supports equality and enables innovation in legal services.

Between 2013 and 2018, the Harvard Law School Library digitized over 40 million pages of U.S. court decisions in collaboration with legal startup Ravel Law, transforming them into a dataset of over 6.7 million cases that represent 360 years of U.S. legal history. The Caselaw Access Project API (CAPAPI) and bulk data service put this important dataset within the reach of researchers, members of the legal community, and the general public.

Learn more about how Caselaw Access Project data is being used in our Gallery and CAP Examples repository on GitHub.

The Caselaw Access Project relies on the support of many at the Law School Library, the Law School and from across the University. We also express our deepest appreciation for the brilliant advice and extraordinary efforts of Jeffrey P. Cunard, Maxine Sharavsky and their colleagues Michael Gillespie, Sarah A.W. Fitts and Robert Williams, Jr. at Debevoise & Plimpton, Henry B. Gutman and colleagues at Simpson Thacher & Bartlett LLP, and Jonathan H. Hulbert and his fellow members of the Office of the General Counsel.
