Law journals and law reviews are collections of articles written by law scholars, lawyers, and students on a specific topic. Not only do they provide analysis of issues, but the citation list and referenced works may provide you with additional direction as you research. It's important to note, however, that many law review articles are written and edited by law students who may lack first-hand experience that practicing law brings.
What are Secondary Sources?
Secondary sources are a great place to start any legal research project. Along with providing a general overview of a topic, secondary sources often contain a rich library of citations and resources which you can use to find additional books and articles on a particular subject.
