Nucleic Acids Research Impact Factor (JIF)

Nucleic Acids Research’s Journal Impact Factor (JIF)

Nucleic Acids Research's Journal Impact Factor (JIF) is the annual two-year citation metric Clarivate publishes for the journal in the Journal Citation Reports (JCR): citations in a given JCR year to Nucleic Acids Research articles published in the preceding two years, divided by the number of citable items the journal published in those two years. Nucleic Acids Research (NAR) is an open-access, biweekly molecular biology and biochemistry journal published by Oxford University Press since 1974 (ISSN 0305-1048 print, 1362-4962 online). Its reported JIF has sat in the low-to-mid-teens across recent JCR releases; Wikipedia's infobox (sourced to JCR) lists 15.0 for the release covering 2024 citation data, though other secondary summaries have reported a lower figure near 13.1 for what is nominally the same data year -- a cross-tracker discrepancy CASRAI has not independently resolved against a live jcr.clarivate.com subscription this session.
