  The concept of citation indexing has become deeply involved in many parts of
research itself and the broad environment in which research plays an integral
role, ranging from research evaluation, numerous indicators, to an increasingly
wider range of scientific disciplines. In this article, we pay tribute to
Eugene Garfield and present a scientometric review of the intellectual assets
that he brought to us. In addition, we explore the intellectual landscape that
has subsequently evolved in connection to many of his ideas. We illustrate what
systematic reviews of the scientific literature may reveal and what we may
learn from the rich information conveyed through citation-induced patterns. The
study is conducted with CiteSpace, one of many science mapping tools based on
data from the Web of Science and Scopus. Without Garfield's inventions, none of
these would be possible.
