English court cases go back in print to at least the 1300's. As might be expected, there have been many versions of case reporters over the years, often titled by the court in which the case was heard (Queens's bench, etc.).
The major dividing line in terms of ease of retrieval is pre-1865 (English Reports)/post-1865 (the Law Reports). Recent (ie. 19th century and onwards) cases can be found most readily in series such as the Law Reports, and the All England Law Reports. Newer UK cases can be found online via Her Majesty's Printing Office. They can also be searched on Lexis and Westlaw. Cardiff University has a useful index to British Legal Abbreviations.
The United Kingdom has been a member of the European Union since 1973. Please see the European Union Research Guide for more information about the EU generally.
