Secondary sources in U.S. law provide analysis and commentary on primary legal sources. They include treatises, law review articles, legal encyclopedias, restatements, and practice guides. These resources help researchers understand complex legal concepts and identify relevant primary sources.

While not binding, secondary sources serve as persuasive authority in legal arguments. Their influence varies based on the court and source reputation. Researchers must evaluate secondary sources critically, considering factors like author credentials, publication date, and intended audience to ensure reliance on credible information.
