Okay, so Mr. West developed a classification system with numerous topics and subtopics and Key Numbers. What next?
Step 1: A West editor reads the new opinion.
Step 2: The editor summarizes each legal issue in a headnote.
Step 3: The editor looks through the 414 topics+ (and subtopics) to find the most relevant Key Number (of the over 90,000 available).
Step 4: The most relevant Key Number is assigned to the headnote.
Step 5: Now, this Key Number can be used to find additional cases about this same narrow issue.
