Outlines services for postrgaduate researchers

What is journal impact factor?

Journal impact factor is the way journals are measured in terms of quality and are a good way to select a journal to publish in. Impact factor measures the number of citations a journal has had over the previous year. It is calculated using the formula: 

Number of citations received in 2019 by items published in the journal in 2017-2018
divided by
Number of citable items published in the journal in 2014-2015

In essence it measures the amount of citation the items in the journal have had during the current year in order to showcase the quality of the journal.
