The impact factor (IF) or journal impact factor (JIF) of an academic journal is a measure reflecting the yearly average number of citations to recent articles published in that journal. The higher the impact factor, in theory, the more weight (prestige) it carries in the given field. Impact factors are calculated yearly starting from 1975 for journals listed in the Journal Citation Reports (JCR), however, the most current impact factor may be from the year prior, not the current year.
Note: Open Access journal impact factors cannot be verified if they are not included in JCR.
