Memorial Library, the UW-Campus EU Depository, has its own research guide with an extensive listing of print resources for treaties, legislation, case law, and other EU documents. See European Union: A Guide to EU Resources (UW Memorial Library) for more information.
The law library also has various print serials, case reporters, and other sets containing EU primary law. If you need assistance with these, and/or you can’t locate what you need in one of the sources listed in the EU LAW Online page of this guide, contact Sunil Rao at strao@wisc.edu
