What is the relationship between encyclopedias and case law in legal research?

• A. Encyclopedias provide background and point to cases; cases are the primary authorities
• B. Encyclopedias are the primary sources of law
• C. Cases have no connection to encyclopedias
• D. Encyclopedias contain the full text of all cases

Answer: (A)

Encyclopedias serve as navigational and explanatory secondary sources in legal research. They provide clear background on a topic, explain how the law has developed, and point you to the leading cases and statutes that illustrate and govern the rule. The actual legal authority is found in the primary sources—case law and statutes—which form the binding rules you apply to a problem. Encyclopedias help you understand the framework, identify which cases are important, and locate the sources where you can read the full opinions. They do not contain the full text of all cases, and they do not themselves establish the law; instead they summarize and guide you to the primary authorities.
