Journal Impact Factor is a quantitative measure for evaluating the relative importance of journal. It counts the average no. of times articles from a journal published in the past 2 years, have been cited in the current year. The Impact Factor was developed by Eugene Garfield at the Institute of Scientific Information (ISI), now owned by Thomson Reuters.
|Journal Impact Factor in 2019 =||No. of citations received in 2019 from all items published in 2017 and 2018|
|Number of citable items (include articles, reviews, or notes that are citable) published in 2017 and 2018|
Example: Calculation of Journal Impact Factor in the Year 2019:
- Citation in 2019 to items published during 2017 and 2018. (Example: 320)
- Number of citable items during 2017 and 2018. (Example: 50)
Meaning articles in a journal published during the past 2 years, have been cited 6.400 times in average in 2019.
