Citation autobiography: An investigation of ISI database coverage in determining author citedness

This article presents a case study investigating the coverage completeness of the Institute for Scientific Information's citation data for specific authors, based on analysis of this author's lifetime citation record, which was compiled through the ISI database, searching the literature for nearly fifteen years, and through various Web search engines. It was found that (with self-citations disregarded) the ISI captured 28.8 percent of the total citations, 42.2 percent of print citations, 20.3 percent of citations from outside the United States, and 2.3 percent of non-English citations. The definition and classification of Web citations are discussed. It is suggested that librarians and faculty should not rely solely on ISI author citation counts, especially when demonstration of international impact is important.
