NOTE: In this tutorial, former librarian Jaci Wilkinson refers to LexisNexis. Since filming, LexisNexis's name has been changed to Nexis Uni and it has a new interface. This video has not yet been re-filmed using the new Nexis Uni interface BUT fortunately it is much more intuitive than LexisNexis.
Nexis Uni went live in late summer 2017. They've compiled a channel of tutorials on YouTube that you might consider watching especially if you want to use advanced features or search case law. This is a good one to get you started:
