Guide to Citation Analysis

Citation Analysis

Citation analysis is the examination of the impact and  assumed quality of an article, an author or an institution based on the number of times works and/or authors have been cited by others. This page includes major resources for citation analysis.

Web of Knowledge 
The ISI Web of Knowledge covers the world's leading scholarly literature in sciences, social sciences, arts and humanities and examines proceedings of international conferences, symposia, seminars, colloquia, workshops and conventions. Series of tutorials are available from its website on how to conduct searches and manage results.

Google Scholar 
Google Scholar is publically available and covers all subjects. its "cited by" feature allows you to track more broadly who is citing you. It has the simple Google search and is generally faster than either Web of Knowledge and Scopus, but you may need to verify that a work is scholarly, and you may need to search variations in author's name since there is no standardized format.

Publish or Perish 
Offers free software you can download to your computer that will retrieve and analyze academic citations taken from Google Scholar. It presents the total number of papers, citations, average number of citations per paper and other parameters related to faculty productivity. An interesting alternative to ISI's Web of Knowledge.

Caveat: While cited references are often used, none of the resources listed above are by any means comprehensive. These resources cover defined subject areas and are limited to certain sources, and thus only contain the citations from these sources.

Other Useful Tools

h-index:  The h-index, or Hirsch index, measures the impact of a particular scientist rather than a journal. "It is defined as the highest number of publications of a scientist that received h or more citations each while the other publications have not more than h citations each (Schreiber, 2008a)." The h-index is included in ISI Web of Science and Scopus. For example, a scholar with an h-index of 5 had published 5 papers, each of which has been cited by others at least 5 times.
