Free Law Project's massive searchable database of federal court opinions

Free Law Project seeks to provide free access to primary legal materials, develop legal research tools, and support academic research on legal corpora.
CourtListener embodies all of these efforts, as the primary free repository of all the court opinions we have collected, as the platform on which we deploy legal research tools, and as the source of bulk downloads that enable academic researchers to study our collection.
We collect legal opinions from court websites and from data donations, and are aiming to have the best, most complete data on the open Web within the next couple years

CourtListener's RECAP archive:
The RECAP Archive is a searchable collection of millions of PACER documents and dockets that were gathered using our RECAP Extensions for Firefox and Chrome. This unique archive was created to partially address what we see as the PACER Problem.
Using this archive, you can finally search and download millions of PACER documents, including those that were originally scanned PDFs, which we laboriously convert to text.
This work was made possible thanks to a partnership with The Center for Information Technology Policy at Princeton, the generous data contributions of thousands of RECAP users, and a ton of volunteer support.
