Scopus vs Web of Science: What Does Your University Accept?
Sep 16, 2026
Not every university accepts Scopus or Web of Science automatically. Your institution's current PhD requirements, research ordinance, and department-level policies determine whether your PhD or publishing requirement is met, not whether database is "bigger" or "better." This guide explains the real difference between the two, and more importantly, how to confirm which one your university actually requires before you submit.
Scopus vs Web of Science: The Short Answer
There is no universal winner. Web of Science is a platform for research citations run by Clarivate, while Scopus is an abstract and citation database run by Elsevier. Some institutions use the term "an indexed journal" without specifying a database at all, while others name Web of Science (or a particular Web of Science index as SCIE or SSCI). The current PhD or publication policy at your university is the sole trustworthy source of information.
Scopus vs Web of Science: What's the Difference?
Both are curated, multidisciplinary citation databases used to evaluate journal quality and track scholarly impact — but they differ in ownership, coverage, and the metrics they generate.
| Feature | Scopus | Web of Science |
|---|---|---|
| Owner | Elsevier | Clarivate |
| Core purpose | Abstract & citation database | Citation indexing & research analytics platform |
| Coverage | Broad, currently indexes a very large number of active journals | Narrower core coverage, but includes deep historical indexing |
| Journal selection | Content Selection and Advisory Board (CSAB) review | Editorial selection process specific to each index within the Web of Science Core Collection |
| Key metrics | CiteScore, SJR, SNIP | Journal Impact Factor (JIF), via Journal Citation Reports |
| Structure | Single unified database | Multiple indexes: SCIE, SSCI, AHCI, ESCI, and others |
| Typical strength | Broader subject and regional journal coverage | Long-established impact factor data, valued in many research evaluation frameworks |
Both databases can index the same journal — but each assigns its own independent status, so a listing in one is never proof of status in the other.
Which Is Better: Scopus or Web of Science?
This is the wrong question for most PhD scholars. The better question is: which one does your specific requirement name? Scopus tends to offer wider journal choice across disciplines, which can help scholars in emerging or interdisciplinary fields. Web of Science, through its Journal Impact Factor and long citation history, is often favored where an institution's research evaluation system is built around JIF. Neither is "better" in the abstract — the right choice is the one that satisfies the rule that applies to you.
If you are unsure which indexed journal fits your university's publication requirement, Zonduo's Scopus journal publication support can help you shortlist journals based on your research area and stated indexing requirement.
Which Does Your University Accept for PhD Publication?
This is the core question, and it cannot be answered generically — it has to be verified against your own institution's current documentation. Use this checklist before you submit anything:
Locate your university's latest PhD regulations or research ordinance (not an old circulated copy).
Search the document for the exact phrase "publication requirement" or "indexed journal."
Check whether Scopus is explicitly named.
Check whether Web of Science is explicitly named.
If Web of Science is named, check whether a specific index — SCIE, SSCI, or AHCI — is required.
Check whether a quartile (Q1/Q2/Q3/Q4) is specified as a minimum.
Note any publication date or timeline requirement tied to the degree.
Confirm whether the journal must be indexed at the time of submission or at the time of publication — this distinction matters and policies differ.
If the wording is vague ("an indexed journal," "a reputed journal"), get written clarification from your department or doctoral committee rather than assuming.
Save a screenshot or PDF of the current indexing status as evidence, since indexing can change after you submit.
If your university's policy simply says "indexed journal" without naming Scopus or Web of Science, do not guess — ask your supervisor or research cell for the specific database they require.
Scopus vs Web of Science for PhD Scholars
For a scholar preparing a publication strategy, the practical differences that matter are:
Compliance first: the journal must satisfy your university's named requirement, not your personal preference for one database.
Subject coverage: some disciplines are more thoroughly represented in one database than the other; check journal lists in your specific field.
Metrics used for evaluation: if your institution references quartiles, confirm which ranking system (Scopus/SJR-based, or JCR-based) it recognizes.
Discoverability: both databases are widely used by other researchers, so either can support visibility once the university requirement is met.
Publication strategy: scholars sometimes shortlist several journals that satisfy the requirement, rather than fixating on one title, to reduce delays from rejections or long review timelines.
For structured help narrowing this down, Zonduo's journal publication support service works from your stated requirement rather than a generic list.
What Are Scopus Q1, Q2, Q3 and Q4?
Scopus divides journals within a subject category into four ranked quartiles based on metrics such as CiteScore or SJR: Q1 is the top 25% of journals in that category, Q2 the next 25%, and so on down to Q4. A journal's quartile is specific to a subject category and a given year — the same journal can sit in Q1 for one category and lower in another, and its position can shift annually. Q1 is not a "Scopus approval level"; it is a relative ranking within a dataset, which is why universities that require a quartile should also specify which ranking system (Scopus or another) they are referring to.
Zonduo's Q1 journal publication guidance can help you interpret quartile requirements correctly before choosing a target journal.
Is a Scopus Journal UGC Approved?
No — Scopus is a database, not an approval authority, and being Scopus-indexed does not by itself mean "UGC approved." UGC-related publication requirements are a separate matter set by the university or the applicable regulatory framework, and they may reference Scopus, Web of Science, or other criteria depending on the current rules in force. Indexing status and institutional or regulatory approval are two different things, and one should never be assumed to guarantee the other. Always check your university's current requirement rather than treating any single database as a stand-in for approval.
Can a Journal Be Indexed in Both Scopus and Web of Science?
Yes. A journal can be indexed in both Scopus and the Web of Science Core Collection at the same time — this is common for well-established journals. However, each database evaluates and lists the journal independently, so its status (active, discontinued, quartile, or specific WoS index) can differ between the two and can change over time. If your requirement allows either database, verify the journal's current status in the specific database named by your university, rather than assuming dual indexing automatically applies. Zonduo's guide on how to check whether a journal is Scopus indexed walks through this verification step by step.
Scopus vs Web of Science vs Google Scholar
Google Scholar is a search engine that crawls scholarly content broadly, including preprints, theses, and non-peer-reviewed material. It is not a curated citation database and does not apply the editorial screening that Scopus or Web of Science use.
| Aspect | Scopus | Web of Science | Google Scholar |
|---|---|---|---|
| Curation | Editorially reviewed (CSAB) | Editorially reviewed (per index) | Automated crawling, no editorial review |
| Typical institutional use | Often named directly in PhD/publication rules | Often named directly, sometimes by specific index | Rarely accepted as sole proof of indexing |
| Metrics | CiteScore, SJR, SNIP | Journal Impact Factor | Citation counts, h-index (not equivalent metrics) |
Because Google Scholar lacks the same curation, it should not be treated as equivalent to Scopus or Web of Science for institutional publication requirements unless your university explicitly says otherwise.
How to Check Whether a Journal Is Really Indexed
Do not rely on a journal's homepage logo, a "Scopus indexed" banner, an old PDF, a third-party aggregator list, or a screenshot circulating online — these can be outdated or, in the case of predatory journals, simply false. Instead:
Verify Scopus status through Scopus's own source/title list.
Verify Web of Science status through the Web of Science Master Journal List, checking which specific index (SCIE/SSCI/AHCI/ESCI) applies.
Confirm the exact journal title and ISSN match — indexing is tied to a specific ISSN, and similarly named journals can have different statuses.
Check the indexing status as of the relevant date — either your planned submission date or the university-specified checkpoint — since a journal's status can change or be discontinued.
Where possible, cross-check with your university's library or research office, which may maintain its own verification process.
Which One Should You Choose?
| University Requirement | Recommended Route |
|---|---|
| Scopus required | Choose a currently active Scopus-indexed journal in your field. |
| Web of Science required | Confirm which specific WoS index is required, then select accordingly. |
| SCIE/SSCI/AHCI required | Verify the exact Web of Science Core Collection index before submitting. |
| Either Scopus or WoS accepted | Compare suitable journals by discipline fit, scope, and timelines. |
| Q1/Q2 required | Confirm which ranking/quartile system your university recognizes. |
| Requirement unclear | Get written confirmation from your department before submitting. |
Final Takeaway
Scopus and Web of Science are both credible, widely used citation databases, but neither is a universal substitute for your university's own rules. The safest approach for any PhD scholar is to treat the comparison as a compliance question first: find your current PhD regulation, identify exactly what it names, and verify the specific journal's indexing status before you invest time in writing and submitting.
Frequently asked questions
Neither is universally better — Scopus generally offers broader journal coverage, while Web of Science is built around the long-established Journal Impact Factor. The right choice depends on what your university's publication requirement names.
Not automatically. Scopus is an indexing database, not an approval authority. UGC-related requirements are separate and should be checked against your university's current regulations.
These are quartile rankings that divide journals in a subject category into four bands based on citation metrics, with Q1 being the top 25%. Rankings are category-specific and can change yearly.
Yes, many established journals are. Each database still evaluates the journal independently, so always verify current status in the specific database your university requires.
Whichever one satisfies your university's stated requirement. If the requirement is unclear, confirm with your department before submitting.
Check the journal's title and ISSN directly against Scopus's source list or the Web of Science Master Journal List — not against the journal's own website or third-party claims.
Generally no, since Google Scholar does not apply the same editorial curation. Confirm with your university if it accepts anything beyond Scopus or Web of Science.
