The Emerging Sources Citation Index (ESCI) is a citation index produced since 2015 by Thomson Reuters, and now by Clarivate Analytics. The ESCI is accessible through the Web of Science, together with Science Citation Index Expanded, Social Sciences Citation Index, and Arts and Humanities Citation Index. Journals in the ESCI are not included in the Journal Citation Reports thus do not receive an impact factor, although they contribute citations to the calculation of other journals' impact factors.
Orbital’s content in ESCI is under consideration, by Clarivate Analytics, to be accepted in the Science Citation Index Expanded™.
Journal Citation Reports™ 2023
Journal Impact Factor™ (JIF): 0.6 (2022)
Journal Citation Indicator (JCI): 0.08 (2022) NEW METRIC
The Journal Citation Indicator is a measure of the average Category Normalized Citation Impact (CNCI) of citable items (articles & reviews) published by a journal over a recent three year period. It is used to help you evaluate journals based on other metrics besides the Journal Impact Factor (JIF). The Journal Citation Indicator will be calculated for all journals in the Web of Science Core Collection™ – including those that do not have a Journal Impact Factor (JIF)™ – and published in the 2022 JCR in June.
