Find Case Law

Search Databases

Databases help search for case law at the federal or state level. If you know the case citation, you can find specific cases more efficiently. Case citation is an essential tool when searching for case law. Citations follow specific rules. For example, the “Board of Education of Topeka, 347 U.S. 483 (1954)” citation includes, in order, the name of the parties, the report’s volume, the reporter’s abbreviation, the first page of the case, and the year. Databases also allow for searches using the Docket Number or topic.

Users can search by source name, citation, term, or topic. Furthermore, users can specify one or multiple categories, including cases, statutes, secondary materials, briefs, administrative codes, etc. In addition, users can also search by jurisdiction and court name, both for federal and state courts. Advanced search can be found by pressing the “More Options” button under the search bar. Advanced search allows you to search by practice area or consult previously saved favorite results.

Under standard search, users can search by term, citation, database, etc., and specify federal or state jurisdictions.  Advanced search allows using connectors and expanders to include or exclude search terms.Consult the training page for more information.
