 How Do I…

Impact Factor (IF) is a quantitative measure of the frequency with which the "average article" published in a given scholarly journal has been cited in a particular period. It is a measure of importance of scientific journals that is calculated each year by the Institute for Scientific Information, and published in the Journal Citation Reports (JCR).
Impact Factors have a controversial influence on the way published scientific research is perceived and evaluated, so a number of other indicators such as H-index, have been adopted to have a better evaluation of authors &/or journals.
JCR or Journal Citation Reports (available under SML databases) calculates the IF and comes in two sections: Science SCIE and Social Sciences SSCI editions in addition to Open Access section:


  1. "Go to Journal Profile" gives IF of a specific journal. Type in at least one word of the journal title; click the needed title to open the journal’s indicators such as IF and Quartile (which is available under 'Rank').
  2. Journals by Rank” by default the list provided is ranked by IF, the highest shown at the top.
  3. Categories by Rank” you may select one or more of these categories to see the list of journals and their IF.
Note: Impact Factor is calculated for only about 10,000 journals, so it could be that the journal you are looking for is not included.
