Over the past few years, we have implemented a series of policy changes for the Journal Citation Reports (JCR)™ aimed at aligning coverage between the Web of Science Core Collection™ and the JCR, providing more transparency of the data underlying JCR metrics encouraging a more inclusive, more holistic way of comparing journals.

Recent changes to the JCR have included the addition of profile pages for journals indexed in the Arts and Humanities Citation Index (AHCI)™ and Emerging Sources Citation Index (EHCI)™ and the introduction of the Journal Citation Indicator (JCI) in 2021. The JCI is field-normalized to facilitate the comparison of journals across different disciplines, including the arts and humanities. We also extended the Journal Impact Factor (JIF)™ to AHCI and ESCI journals in 2023 so that it now encompasses all quality journals in the Web of Science Core Collection.
