How to Make Sure of a Journal Impact Factor & Its Indexing Information

By Mohamad Mostafa, Knowledge E

Journal Impact Factor (JIF) of an academic journal is an indicator of the impact of a journal with respect to the quantity of scholarly research published in that journal. The JIF is calculated by dividing the number of citations received in a certain year for articles published in that journal during the two preceding years, by the total number of scholarly research papers published in that journal in those years. The Journal Citation Reports (JCR) is an annual publication released by Clarivate Analytics (formerly Thomson Reuters and ISI) that publishes the JIF for more than 10,000 academic journals.

Several misleading metrics and fake impact factors have appeared which damage the prestige of scholarly journals. For example, Universal Impact Factor (UIF), Global Impact Factor (GIF), and Citefactor Impact Factor. In addition to this, there is misleading and false information about indexing in Web of Science.
