Goal: Narrow the field of all legal information to the subset of authority necessary to analyze a legal issue

Three Ways to Begin

• Retrieve documents from a known citation (e.g. 100 US 4)
• Pre-filter by jurisdiction, topic and/or type of authority (source-driven research) and search only those sources
• Search in federated (i.e. aggregated) content and then filter the results by jurisdiction, topic and/or type of authority
