Fair Use Index - Copyright.gov"Tracks a variety of judicial decisions to help both lawyers and non-lawyers better understand the types of uses courts have previously determined to be fair—or not fair. The decisions span multiple federal jurisdictions, including the U.S. Supreme Court, circuit courts of appeal, and district courts. Please note that while the Index incorporates a broad selection of cases, it does not include all judicial opinions on fair use. The Copyright Office will update and expand the Index periodically." - Fair Use Index explainer page on Copyright.gov
