Caselaw Access Project – 360 Years of United States Caselaw
From the about page:
The Caselaw Access Project (“CAP”) expands public access to U.S. law.
Our goal is to make all published U.S. court decisions freely available to the public online, in a consistent format, digitized from the collection of the Harvard Law Library.
…
CAP includes all official, book-published United States case law — every volume 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 our most recent cases are from 2018.
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 plan to share (but have not yet published) page images and page-level OCR data for all volumes.
…
On the bright side, 6.4 million unique cases, 40M pages scanned. On the dark side, access is limited in some situations. See the website for details.
Headnotes for volumes after 1922 are omitted (a symptom of insane copyright laws) but that presents the opportunity/necessity for generating headnotes automatically. A non-trivial exercise but an interesting one.
Take note:

You can report errors of all kinds at our Github issue tracker, where you can also see currently known issues. We particularly welcome metadata corrections, feature requests, and suggestions for large-scale algorithmic changes. We are not currently able to process individual OCR corrections, but welcome general suggestions on the OCR correction process.
