What is the Emerging Sources Citation Index?

An introduction to the ESCI for journal editors-

What is the ESCI?

The Emerging Sources Citation Index (ESCI) launched in late 2015 as a new database within Web of Science. Around 3,000 journals were selected for coverage at launch, spanning the full range of subject areas.

What are the requirements for indexing?

The selection process is the first step in applying to other Web of Science indexes. These include the Science Citation Index (SCI), Social Science Citation Index (SSCI), and Arts and Humanities Citation Index (AHCI).

Journals accepted for coverage must meet the following criteria:

  • Peer reviewed
  • Follows ethical publishing practices
  • Meets technical requirements
  • Has English language bibliographic information
  • 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 be evaluated and (if successful) indexed in the ESCI while undergoing more in-depth editorial review.

Timing for evaluation follows 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 which are indexed can opt out of consideration for further evaluation if they need to improve their citation profile before evaluation for the flagship indexes.

Journals can also move from the flagship indexes to the ESCI if they no longer meet the conditions of flagship index coverage.

Web of Science

Journals indexed in the ESCI will not receive Impact Factors. However, citations from the ESCI will 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 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 in 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 journal’s citation performance.

What are the benefits?

Indexing 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 indexed journal, similar to what already takes places with other Web of Science databases.
