A journal’s Impact Factor is the average number of citations received in the last year to articles published in the previous two years. It is measured each year by Clarivate Analytics and reported in the Journal Citation Reports (JCR). The 2017-JCR analysis released in 2018 is based on citations in 2017 to articles published in 2015 and 2016.
The Journal Impact Factor is often misused as an indicator of an article’s or author’s impact and its use is problematic, including to determine the quality of a journal. High citation rates can have a disproportionate effect on the mean number of citations per paper. For this reason, we are committed to building alternative and comprehensive impact metrics for articles, authors and journals and are a signatory to DORA, supporting the responsible use of journal impact metrics.
