Secondary sources are essential tools in legal research, offering valuable insights and context for primary law. They include law reviews, encyclopedias, treatises, and restatements, each serving unique purposes in legal analysis.

These sources provide explanations, historical context, and trend analysis, helping researchers understand complex legal issues. While not binding, secondary sources can be persuasive, with their authority varying based on factors like author reputation and court preferences.
