Emerging Sources Citation Index
citation index produced since 2015 by Thomson Reuters, and now by Clarivate Analytics
The Emerging Sources Citation Index (ESCI) is a citation index produced since 2015 by Thomson Reuters and now by Clarivate. According to the publisher, the index includes "peer-reviewed publications of regional importance and in emerging scientific fields".
The ESCI is accessible through the Web of Science, together with other Clarivate indexes. As of June 2021, all journals indexed in ESCI are also included in the Journal Citation Reports. While these journals still did not receive an impact factor until the next year, they did contribute citations to the calculation of other journals' impact factors. In July 2022, Clarivate announced that journals in the ESCI obtain an impact factor effective from JCR Year 2022 first released in June 2023.
Inclusion criteria
To be included in the ESCI, journals must be:
Peer reviewed
Follow ethical publishing practices
Meet technical requirements
Have English language bibliographic information
Be recommended or requested by a scholarly audience of Web of Science users
Criticism
Jeffrey Beall argued that among the databases produced by Clarivate, the ESCI is the easiest one to get into and that (as a result) it contains many predatory journals.

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Apr 27, 2026. The linked authority identifier is Q22908122. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2015, 2021, 2022 and 2023.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
