Finding English Cases

Prior to 1865, there was no official series of law reports. Even today, the UK government does not publish an official reporter. However, both its Courts and the Bluebook suggest citing to the English Reports for pre-1865 cases whenever possible. After 1865, cite to the official Law Reports. Other reporters, such as the Weekly Law Reports and the All England Law Reports, may be used if a case has not been reported in the Law Reports.
