California’s court opinions are a critical part of the United States’ legal operating system, yet until recently, our country’s legal records have been kept behind the paywalls of LexisNexis and Westlaw and printed in books available only to a limited few. Harvard Law School (Harvard) has collaborated with Ravel Law (Ravel), an analytics startup, to take on these goliaths.

Together, they have open-sourced the school’s database of U.S. case law, which allows lawyers, law students, academics and the general public to retrieve case laws free of charge. Ravel has also added “powerful tools” to sift through this vast database.
