AltLaw

AltLaw is an American academic project aimed at making federal appellate and Supreme Court case law publicly available, "'to make the common law a bit more common.'" The project is a collaboration between Columbia Law School's Program on Law and Technology and University of Colorado School of Law's Silicon Flatirons program.

Currently the digital access to US Case Law is dominated by LexisNexis and Westlaw, charges for access to which can run in the hundreds of dollars per hour.

The data in AltLaw is roughly 200,000 cases decided between 1990 and 2007, made available on US Circuit Appeals and Supreme courts web sites, all linked to from uscourts.gov, and collected by Prof. Paul K. Ohm at University of Colorado Law School.
