“A citator is a compilation showing where certain cases have been cited in other cases, and whether the provisions of constitutions and statutes have been repealed, amended, or otherwise affected, or have been judicially construed, or have been cited.” Frank Hall Childs, Where and How to Find the Law 61 (1922).
citator
citator (sI-tay-t[schwa]r). A catalogued list of cases, statutes, and other legal sources showing the subsequent history and current precedential value of those sources. • Citators allow researchers to verify the authority of a precedent and to find additional sources relating to a given subject. Citators were originally printed on gummed paper and pasted next to the report of a cited case. Today, citators are published in volumes and are also available online; the two most popular are Shepard’s and KeyCite.
