Some online research really lends itself to easy keyword searches, e.g. HIPAA Omnibus Rule Compliance Checklists (but you still have to read the laws – no shortcut there)
Another easy word search if you are researching a new topic and want to explore the legal literature: libguides [subject]
For example, try these in your favorite search engine:
libguides hipaa
libguides aviation
libguides juvenile law
