From the page: The Caselaw Access Project scanned the entirety of the Harvard Law School Library's physical collection of American case law and made it machine-readable in a consistent format available online. This process was funded in part by an industry partner who worked with us for the first few years post-digitization to provide access to the data to researchers and the public, rather than other commercial entities. To facilitate that agreement, the Library Innovation Lab (LIL) maintained the case.law website as the primary access point for the data. Those agreements have now expired, and there is no longer a need to have any form of metered access to the data.

CAP includes all official, book-published state and federal United States case law through 2020 — every volume or case designated as an official report of decisions by a court within the United States.

Our scope includes all state courts, federal courts, and territorial courts for American Samoa, Dakota Territory, Guam, Native American Courts, Navajo Nation, and the Northern Mariana Islands.

Our earliest case is from 1658, and we currently include all volumes published through 2020.

Each volume has been converted into structured, case-level data broken out by majority and dissenting opinion, with human-checked metadata for party names, docket number, citation, and date.

We also offer PDFs with selectable OCR text for each case published up to 2018.
