Dear Francisco,

Same question was asked before. The good answer from my opinion was:  

Wasu Pathom-aree · 25.84 · 54.32 · Chiang Mai University

Yes, the journals index in this ESCI will not be issued an impact factor. However, each journal in this new index will be evaluated every year and those qualified will be transferred to SCIE. That's what I heard from Thomson Reuters in the meeting in Bangkok recently.

Best wishes,

Mansour

ESCI is a subset of JML but the ESCI journals do not necessarily advance further to JCR (see e.g. the Youtube video from WoS linked below). On the other hand, it does not appear to me that the journals which will be advanced to JCR will necessarily go through ESCI.

I think that Journal Master List is a list of all journal list covered by Web of science (all the products and subproducts)

Emerging Sources Citation Index is created for cover the deficiencies of Science citation index, that.s mean, it incldes all journals are being evaluated to become part ofWeb of Science Core Collections (Science Citation Index, Social Science Citation Index and Arts & Humanities Citation Index).

I appreciate anybody if explain to me what is the difference between Web Of Science and master journal list?

Dear Francisco M. Aliaga 

All the above answers are very informative. I think, you got the desired information.  

Dear Mehdi Rezaei

Web of Science (previously known as (ISI) Web of Knowledge) is an online subscription-based scientific citation indexing service maintained by Thomson Reuters that provides a comprehensive citation search. While, the Master Journal List is a journal list which includes all journal titles covered in Web of Science.

Ciavarella Manager | Publisher Relations| #fbm15 @thomsonreuters @webofscience in https://www.slideshare.net/StateOfInnovation/emerging-sources-citation-index-a-new-edition-of-web-of-science (2015)

https://www.slideshare.net/StateOfInnovation/emerging-sources-citation-index-a-new-edition-of-web-of-science

A very interesting source!,

Thankyou

Emerging Source Citation index (ESCI) is a part of Web of Science. It is an indexing data base of Thomson Reuters. The journals indexed in ESCI will not get the impact factor. But the papers cited in ESCI database will be included in Journal Citation Report. It is the first stage of a Journal to be included in ESCI database. Moving forward to SCI or SCIE. Thank You. 

Many colleagues have already explained very well about ESCI. This is a content coverage of Thomson Reuters (now Clarivate Analytics). However, the journals covered under ESCI are not in Journal Citation Report (JCR).

Very interesting answers

Thank you all 

Is there Thomson Reuters impact factor for ESCI journals.

Thank you @Mansour. @Renjith, the common metrics for journals in ESCI are:

CiteScore

Source Normalized Impact per Paper (SNIP)

SCImago Journal Rank (SJR)

All the best!

What is the difference for a journal cited in ESCI and not in WOS? in terms of quality

Very informative answers and have learnt a lot. Thanks

SCI=SCIE=ESCI=ISI Journal...

Clarivate Analytics = WoS = Thomson Reutres = Web of Knowledge = ISI Journal

Thank you very much for your informative answers. The ESCI is a part of Collection Core of Thomson Reuters. As noted by other colleagues, it is an primary indexing for journals that want to enter in the main indexes of WoS including AHCI, SCI (SCIE) and SSCI.

No point publishing your work in ESCI journals unless you are sure the journals will eventually be selected for coverage in the JCR.

The best thing to do is to approach your academic superiors and ask them if it is acceptable for you to publish in non-citation indexed journals. In some countries, any journal that is peer-reviewed, regardless of whether it has an impact factor or not, is considered superior to a book chapter. If you have already met your quota of required SSCI articles and are writing something for political reasons or for a cause not related to proving research excellence, it may be deemed more appropriate to target the audience of a non-SSCI journal.

I found an explanation here:

https://en.wikipedia.org/wiki/Emerging_Sources_Citation_Index

One sentence that terrifies me though:

"The ESCI index is called the prestige of the Predatory open access publishing."

Thank you Orven!

You’re welcome, @Omid.

SHOULD WE CONSIDER ESCI AS A SCI JOURNAL?

NO. They do not enjoy equal status

Why some journals indexed in ESCI have impact factor and some do not? How to calculate impact factor of journals in ESCI?

It was also my question, thank you all for your valuable replays !

The selection process for ESCI is the first step in applying to the Science Citation Index (SCI), Social Science Citation Index (SSCI) and Arts and Humanities Citation Index. If a ESCI journal qualifies the evaluation, it appears to be in Science citation index. So ESCI is an intermediate state. It may or may not qualify to Science citation index or Science citation index-expanded.

Informative discussion.

Useful discussion.

Content in ESCI is under consideration by Clarivate Analytics, the owner of Web of Science, for additional indexing on the platform, including for the Science Citation Index Expanded, the Social Sciences Citation Index, and the Arts & Humanities Citation Index.

SCIE: Science Citation Index Expanded

A list of top notch journals by Clavariate Analytics (indexed by Thomson Reuters). These journals are evaluated for calculating impact factor every year based on citations, published papers, reach of the papers etc.

ESCI: Emerging Sources Citation Index

A new type of list in which journals who applied for SCIE gets listed initially while the evaluation is going on. And journals of local importance also gets included in this list. But there is no indexing of papers in Thomson Reuters and also no impact factor is calculated for such journals.

Does. it mean that one should only publish in SCI or SCOPUS journals

Now the question is what about the Research Papers published in journals not covered by SCI or SCOPUS?

Not all SCOPUS journals are indexed in SCI/SSCI so make sure the journals you target have impact factors

The Emerging Sources Citation Index is a citation index produced since 2015 by Thomson Reuters, and now by Clarivate Analytics. According to the publisher, the index includes "peer-reviewed publications of regional importance and in emerging scientific fields".[1] It has been observed that among the databases produced by Clarivate Analytics, the Emerging Sources Citation Index is the easiest one to get into and that as a result it contains many predatory journals.

Together with Science Citation Index Expanded, Social Sciences Citation Index, and Arts and Humanities Citation Index, the Emerging Sources Citation Index is accessible through the Web of Science.

ABSTRACTING / INDEXING

Clarivate Analytics: Social Sciences Citation Index (SSCI)

I found in a journal that it is abstracted / indexed in Clarivate Analytics: Social Sciences Citation Index (SSCI). What it means? Whether the journal will get impact factor in near future?

I am agree with Bashar Mohammad Al Najdawi!

ESCI seems to act like an antechamber to a future probable inclusion in Web of Science SCIE with an impact factor.

Your can check below link for details of ESCI

https://editorresources.taylorandfrancis.com/understanding-research-metrics/esci/

Actually ESCI as discussed earlier is a part of clarivate analytics no doubt about that, as far as I understand the question is whether one if published under this cat can be recognized as ISI indexed or scopus? The answer is yes its also ISI indexed but with no impact factor (reason of no IF already mentioned earlier) so its easy to get published here under the same indexing but no IF. For scopus , this discussion would not help because its only about Clarivate . Scopus status can be checked separately in SCImagojr. All journals under ESCI have no IF.

Thanks

Does it mean that we should publish only in SCI or SCOPUS indexed journals only where as all r covered by Clarivate only.

ISI-IF is three categories: ESCI, SCIE then SCI. First of all, journals accepted for coverage in ESCI must meet the criteria of:

1) Peer reviewed

2) Follows ethical publishing practices

3) Meets technical requirements

4) Has English language bibliographic information

5) Recommended or requested by a scholarly audience of Web of Science users

Then after that, the journal must be under revaluation for year or more. If Clarivate Analytics found the journal is suitable, it will be classified under the name of ESCI and become ISI master list without Impact Factor. Later on, if the journal get IF, it will be classified under SCIE

Now all journals listed in ISI Master list may not be in Journal Citation Report (JCR).

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.

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

For the second part of the question, it is definitely worth to publish PhD works in ESCI journals.

Best regards,

The Emerging Sources Citation Index (ESCI) journals are just applicants for inclusion in the Web of Science database. These journals are accessible through the Web of Science but will not receive Impact Factors. The Science Citation Index (SCI) is a highly selective subset of journals found in the Science Citation Index Expanded. Journals in SCI are typically the most consistently high impact titles in many scientific disciplines.

The Master Journal List includes all journal titles covered in Web of Science. You can also check the by using this URL, http://mjl.clarivate.com/cgi-bin/jrnlst/jlresults.cgi?PC=MASTER&ISSN=1533-0028

You can always go with ESCI journals, just ensure they are under Elsevier, Springer, Wiley, Emerald or T&F, don't get bogged down by the mindless technical babbling from different morons.
