What is the Emerging Sources Citation Index?

The Emerging Sources Citation Index (ESCI) was launched in late 2015 as a new database within Clarivate Analytics’ (formerly Thomson Reuters’) Web of Science.  Around 3,000 journals were selected for coverage at launch, spanning the full range of subject areas. As of February 2017, the database contains 5,578 journals, approximately 530 of which are Taylor & Francis journals. This means around 20% of our journals are indexed in the ESCI.

What are the requirements for indexing?

The selection process for ESCI is the first step in applying to the Science Citation Index, Social Science Citation Index and Arts and Humanities Citation Index. Journals accepted for coverage in ESCI must be peer reviewed, follow ethical publishing practices, meet technical requirements, have English language bibliographic information, and be recommended or requested by a scholarly audience of Web of Science users.

All journals submitted for evaluation to the core Web of Science databases will now initially be evaluated for the ESCI, and if successful, indexed in the ESCI while undergoing the more in-depth editorial review. Timing for ESCI evaluation will follow Clarivate Analytics' priorities for expanding database coverage, rather than the date that journals were submitted for evaluation. If a journal is accepted from the ESCI to another database it will no longer be covered in the ESCI. Journals indexed in the ESCI can opt not to be considered for further evaluation at that time if it is felt that it needs to improve its citation profile before evaluation for the flagship indexes. Journals can also move from the flagship indexes to the ESCI if it is felt they are no longer meeting all the conditions of flagship index coverage.

ESCI in Web of Science

Journals indexed in the ESCI will not receive Impact Factors; however, the citations from the ESCI will now be included in the citation counts for the Journal Citation Reports, therefore contributing to the Impact Factors of other journals.

If your journal is indexed in the ESCI it will be discoverable via the Web of Science with an identical indexing process to any other indexed journal, with full citation counts, author information and other enrichment. Articles in ESCI indexed journals will be included in an author’s H-Index calculation, and also any analysis conducted on Web of Science data or related products such as InCites. Taylor & Francis can also use this data to provide you with a more detailed understanding of your journals citation performance.

What are the benefits?

Indexing in the ESCI will improve the visibility of a journal, provides a mark of quality and is good for authors. We have already seen examples of institutions and funders suggesting publication in an ESCI listed journal, similar to what already takes places with other Web of Science databases.
