Conflict of Laws


Written by legal scholars and practitioners, treatises provide current, in-depth analysis of an area of law and include citations to relevant sources, including case law, statutes, regulations, and law journal articles.


Produced by the prestigious American Law Institute, Restatements of the Law address uncertainty in the law and attempt to clarify, modernize, and otherwise improve the law.

West Key Number System

A West Key Number comprises a topic and a number that together refer to a specific subtopic within the broader legal topic. It is a very helpful classification system for researching case law using either Westlaw Edge or one of their print digests, including West's Federal Practice Digest and West's Atlantic Digest, both of which are on the second floor of the Burns Law Library. The same Key Number can be used in any West source.
