JOURNAL IMPACT FACTORS
The impact factor of a journal is a measurement that reflects the average number of times that articles in a particular journal have been cited. The measurement changes from year to year, and is based on data from the previous two years. This measurement is often used to estimate the relative importance of a journal in its particular science or social science field.
Please note: Not all journals are included in JCR and so every journal may not have an impact factor. There are also many other considerations for determining the importance and quality of a journal beyond the impact factor.
