A legal citation, or "cite," is a reference to a specific legal source, like a court case, a law, or a scholarly article. Generally, a standard citation includes the volume number, the abbreviated title of the source, and a page or section number.
If you have a citation and you cannot decipher what the abbreviation means, you can use:
