If you are writing a case note, or if you are writing a comment in an area that turns on notable leading cases, you can use the case or cases as an entry-point for research. The same is true for statutes and, to a lesser degree, federal regulations.
Try these techniques:
Shepardize the case on Lexis, and KeyCite the case on Westlaw. Consider limiting your results to law review articles and treatises/practice guides.
Run case-name searches in the Index to Legal Periodicals and Books, and Current Index to Legal Periodicals to find the most current articles about leading cases. For a more information on finding articles, see the Articles-Legal tab in this guide.
Use PACER or Lexis, Westlaw or BloombergLaw to find litigation documents (briefs, pleadings, etc.) for recent federal cases. (For more about PACER, ask a Garbrecht Law Library Reference Librarian.)
Try these techniques, the first two of which may also work for federal regulations:
Bring up the statute on Lexis and Westlaw, and check the annotations.
Shepardize the statute on Lexis, and KeyCite the statute on Westlaw. Consider limiting your results to law review articles and treatises/practice guides.
Run statute-name searches in the Index to Legal Periodicals and Books, and Current Index to Legal Periodicals to find articles about leading cases. For a more informaiton on finding articles, Articles-Legal tab, this guide.
