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 or one of their print digests, including West's Atlantic Digest, which is on the second floor of the Burns Law Library. The same Key Number can be used in any West source.
