Q. What is Shepard's? What is Keycite?
What do those services do? Why are they important?
Shepard's and Keycite give the history and treatment of a case, law or regulation by later cases. They are called citators or citation services. These services tell you if you are relying upon good law to make your point. These services tell you if a case has been overturned or criticized by later cases or if the case has been looked upon favorably.
You must use a citation service as part of your legal research because New York courts follow the doctrine of stare decisis.
You must come to a Public Access Law Library to use these services. Shepard's is on LexisAdvance and Keycite is on Westlaw..
