Legal Research and Writing Guides

The Law Library has several resources dedicated to legal research and writing. Please drop by the library and peruse our Practical Skills collection.


Introduction - Start Here!

Welcome to the Law Library's Guide to Legal Research! Researching the law can be complicated, but this guide will help you figure out what kind of law you are looking for, and then point you toward some resources that can help you find what you need.

If you're researching a certain topic but you're not sure where to start, try the Law Topics by Subject tab. That page contains links to several secondary sources that can help sort out the kind of laws that may be relevant to a particular topic.

While you are considering what kind of law you may be looking for, you also need to consider what level of law you may want to look for. Laws can reach only as far as one small town, or they can apply to many countries at once. Most legal research in the United States looks at laws that are created by the United States Government, that apply to the whole country (also called "federal law"), or laws that are created by state governments, to apply only in that particular state (called "state law").

Once you have a sense of what kind of law you want to look at, and what levels of law you want to look at, you can move into finding primary sources of law. There are three basic kinds of law, one produced by each of the three branches of government:

Foreign law refers to laws that apply in other countries, such as French law or Japanese law. International law is the law that governs interactions between countries, such as treaties or United Nations materials. If you are looking for foreign or international law, click on the Foreign and International Law tab.

Finally, while this guide mostly links to electronic resources, there are many more resources and several helpful librarians at the Law Library. Legal research is complicated, so feel free to drop by if you need more help!



Making Sense of Legal Citations

A legal citation generally consists of some combination of the following elements:

  • the author/names of the case, article, law or other resource.
  • a numerical designation that identifies which part of a larger set the source is located in.
  • the abbreviated name of the resource that the source is located in.
  • the page or section number in which the cited source can be found.
  • the year or publication date of the source. Court cases often include the name of the court here.

When searching or retrieving documents by citation in legal databases, leave off the title or name and the date of the document.   Here are some examples of different types of legal citations:
