Short answer: Academic journal delisting occurs when an indexing database stops covering a journal after re-evaluation, such as when a title no longer meets applicable quality criteria or when publication practices raise concerns. Scopus and Web of Science have their own policies and procedures for reviewing journal coverage.
Indexing is not necessarily permanent. Journals can be evaluated again after entering a database, and coverage can change when a title no longer meets the relevant standards or when publication practices raise concerns. For authors, the practical lesson is straightforward: do not treat an old indexing claim, a journal website badge, or a previous database record as proof of current coverage.
What delisting means
In ordinary author language, “delisting” means that a journal is no longer receiving new coverage in an indexing database. The exact consequences depend on the database and the reason for the change. Existing records may remain visible, while future content may stop flowing into the database.
This distinction matters. A journal’s historical presence in Scopus or Web of Science does not automatically mean that new articles will continue to be indexed after coverage is discontinued or changed.
How Scopus handles title re-evaluation
Elsevier’s Scopus content-policy page explains that titles can be flagged for re-evaluation based on signals and other concerns. The Content Selection and Advisory Board re-evaluates flagged titles using the same review criteria applied to newly suggested titles. During re-evaluation, content flow can be suspended.
If a title is discontinued, already indexed content generally remains part of the scientific record. Elsevier also notes that, in exceptional cases involving proven and severe unethical publication practices, previously indexed content may be removed. Scopus publishes updates to its discontinued-source information.
How Web of Science handles re-evaluation
Clarivate describes Web of Science Core Collection as a dynamically curated collection. Its editorial selection process includes 28 journal criteria: 24 quality criteria and four impact criteria.
Journals that no longer meet the applicable quality criteria can be removed from the Core Collection. Therefore, current inclusion should be verified rather than treated as a permanent guarantee of future coverage.
How authors should verify current status
When indexing status matters, check the current official source immediately before relying on it. For Scopus, use the current Scopus source information and discontinued-source information. For Web of Science, use the Master Journal List and review the current coverage details.
Clarivate provides the Master Journal List as a freely available resource for checking journal information and coverage changes. This makes the official database information more useful for verification than relying solely on a publisher’s own “indexed in” page. See our guide on how to check journal indexing for a step-by-step walkthrough.
Why a journal’s own claim is not enough
A publisher may accurately describe a journal’s historical indexing status while its website remains unchanged after a database decision. A publisher may also use database logos or broad wording that does not identify the exact collection or current coverage period.
For this reason, authors should treat the publisher’s indexing page as a claim to verify rather than the verification itself. The same principle applies to screenshots, old certificates, third-party indexing lists, and SEO pages that reproduce database information without a current source date.
What authors should do after discovering a change
If you are preparing a manuscript, verify the journal again before submission. If indexing status matters for promotion, graduation, funding, or institutional reporting, ask the relevant institution which database, collection, and publication date they recognize.
If an article has already been accepted or published, preserve the database evidence you relied upon and ask the relevant institution or database support team how a subsequent coverage change affects your specific situation.
Avoid assuming that a change in indexing status automatically means that previously published research is invalid. Indexing decisions and research-quality judgments are separate questions. The useful task is to establish the current coverage status and understand what the relevant database says about the title.
Practical checklist
- Check the journal’s exact title and ISSN.
- Verify current Scopus status using official source information.
- Check Scopus discontinued-source information where relevant.
- Verify current Web of Science coverage in the Master Journal List.
- Identify the exact Web of Science collection if it matters for your institution.
- Record the date on which you checked the status.
- Do not rely solely on the journal’s own indexing page or database badge.
- Re-check status close to submission, acceptance, and any institutional reporting deadline.
