Changes to West Key Number System

West has just announced that it has added more than 3,000 new key number classifications to the West Digest System topic, Constitutional Law.  West also issued this handy reminder to researchers using the West Digest System online:

Remember: When an existing headnote is reassigned to a different or newly created West topic or key number, the former topic or key number remains visible--and searchable--in the appropriate case law database on Westlaw. As a result, you can retrieve a case using either its current or its former West topic and key number classifications.
