From 2016 a volume 4 was added to the WLR service. The new 4 WLR is only available online. It contains "additional cases which, while not meriting full print publication, add useful knowledge and provide helpful recent examples of the application of settled law, in a form that can be cited as a complete case report."
Holders of an Oxford SSO can access them via LexisLibrary, Westlaw Edge UK and/or ICLR Case Reports
