Citators, like KeyCite (available on Westlaw), Shepard's (available on Lexis), and BCITE (available on Bloomberg Law), can help attorneys determine if a case is "good law". They also provide references to additional legal materials, including treatises and law reviews.
"Citators perform three major functions:
- They provide parallel citations and references to other proceedings in the same case, allowing you to trace a case’s judicial history;
- They indicate if subsequent cases have overruled, limited, or otherwise diminished a case’s precedent, enabling you to determine whether it is still good law; and
- They list citing cases, as well as treatises, law review articles, and other resources, providing research leads needed to trace the development of a legal doctrine forward in time." Kent C. Olson, Principles of Legal Research § 8.5, at 289 (2009).
