Researching “the law” on a particular topic is generally a multi-step process that involves checking secondary sources followed by primary sources - statutes, cases, and sometimes, administrative rules or regulations. Very rarely is there a simple answer to a legal question or a single book that will provide the answer.
Where you start depends largely on what information you already have. If you already have a citation - for example, to a statute or a case - it may provide a jumping off point to additional sources. If you don't have a citation, or are unfamiliar with an area of law, secondary sources are the best place to start. Secondary sources, which are not the law, provide background information, an introduction to the terminology of a particular topic, and valuable citations to primary sources of law (statutes, cases, administrative rules).
