Legal materials can fall into two different categories: (1) Primary and (2) Secondary. Secondary sources are about the law. They explain, analyze, interpret, discuss, and cite to primary sources. Primary sources are the law themselves. This guide covers researching federal law with an emphasis on the primary sources.
Remember that research is a process. If you do not know much about a legal subject, the flow chart below is a helpful process to follow. Your research strategy will change depending on what you know, the resources to which you have access, your budget, your time, and what you discover as you research.
The first step in the research process is to analyze the problem and to ask questions. The second step is to consult secondary sources. The third step is to answer the question is it common law or statutory or do you have a cause of action that can be filed under both? Your secondary source research can help with that.The fourth step branches out depending on if you have a common law or statutory law issue. If it is a common law issue, you will read cases suggested by your secondary sources and find cases using headnotes and topic and key numbers. If your issue is statutory, you will consult the annotated code. You want to update the annotated code with the pocket part or supplement and the Legislative Service if you are working with print resources. The annotated code will give you case summaries for important cases that interpret the statute. After consulting the annotated code for a statutory issue, you will move on to finding cases. You will look up the full-text of the cases you found in the annotated code, look at the cases suggested by secondary sources, and look for more cases using the headnotes and topic and key numbers. If you are not able to find case law for your statutory issue and the statutory language is ambiguous, you will do legislative history research. Also, any time you have a statutory issue, you will need to find any applicable administrative regulations and update those regulations.You will want to consult administrative adjudications. Regardless of whether you have a statutory or a common law issue, you will need to make sure your cases are good law. You will Shepardize or KeyCite your cases. If this is a statutory issue, you will also need to Shepardize or KeyCite the statutes and regulations. Stop researching when you keep finding the same information over and over again.
