I'd like to add to my Academic Legal Writing book a list of research tips, chiefly focused on things many law students don't know about, but should know about. They could be very specific things (the Lexis ATLEAST and NOT W/ connectors, Westlaw SY,DI() searching, the various 1600s, 1700s, and 1800s full-text searchable databases of books and newspapers) or broader research concepts that people miss. Any suggestions that you'd like to pass along?
