Citation indexes track references that authors put in the bibliographies of published papers. They provide a way to search for and analyze the literature in a way not possible through simple keyword/topical searching. It also enables users to gather data on the "impact" of journals, as well as assessing particular areas of research activity and publication. This field is called bibliometrics.
