What is a journal impact figure?
The impact factor is a measure normally based on the frequency with which the average article in a journal has been cited in a particular year. It is used to help scholars decide on the best journals in which to publish their work, and to help readers and researchers discern the relative importance of journals within their fields.
How can I find an impact factor for a journal?
Unfortunately, WKU Libraries does not currently have access to Journal Citation Reports, the best-known source for journal impact factors. Impact factors for some journals may, however, be found through WKU Libraries in Cabell's Directory, particularly for those journals related to business, education, nursing, and computer science.
The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal based on the number of citations, weighted by the ranking of the citing journal. Many scholars regard it as a more robust measurement than those provided by Journal Citation Reports. The Eigenfactor website allows you to search by journal title, category, and year.
SCImago Journal Rank (SJR indicator) is a free online resource providing a measure of scientific influence of scholarly journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from. SJR Indicator’s database of journal rankings is searchable by topic, journal title, and country of publication.
Google Scholar Metrics provide an easy way for authors to quickly gauge the visibility and influence of recent articles in scholarly publications. To access, go to the Google Scholar page and click the “Metrics” link at the top of the page. Google Scholar provides the following metrics:
Not to be outdone, Microsoft created Academic Research in response to Google Scholar, and has added a journal ranking system based on the number of times a journal has been cited in the last 5 or 10 years.
