According to Wikipedia, the journal impact factor is a measure reflecting the average number of citations to articles published in scientific journals. It is frequently used as a proxy for the relative importance of a journal within its field, with journals with higher impact factors deemed to be more important than those with lower ones. The impact factor was devised by Eugene Garfield, the founder of the Institute for Scientific Information (ISI), now part of Clarivate. Impact factors are calculated yearly for those journals that are indexed in Clarivate’s Web of Science (WOS).
