At its most basic definition the practice of law comprises conducting research to find relevant rules of law and then applying those rules to the specific set of circumstances faced by a client. However, in American law, the legal rules to be applied derive from myriad sources, complicating the process and making legal research different from other sorts of research. This text introduces first-year law students to the new kind of research required to study and to practice law. It seeks to demystify the art of legal research by following a “Source and Process” approach. First, the text introduces students to the major sources of American law and describes the forms the various authorities traditionally took in print. After establishing this base, the text proceeds to instruct students on the methods they will most likely use in practice, namely electronic research techniques and the consultation of secondary sources. Sources of Law incorporates screencasts currently hosted on YouTube that actively demonstrate the processes described in the static text. Finally, the text illustrates how the different pieces come together in the legal research process.
