Updating Federal Cases Using Citators--KeyCite & Shepard's

Citators use flags and signals to notify you if a case has been:

  • reversed;
  • overruled; or
  • superseded by a statute.

Citators also provide other cases and secondary sources that cite a case

KeyCite is the citator for Westlaw. Shepard's is the citator for Lexis.  Some public libraries in South Carolina provide access to Westlaw for their patrons, while some South Carolina colleges and universities, including the University of South Carolina, provide access to Nexis Uni (by Lexis).
