Is ScienceDirect Peer Reviewed? What the Platform Hosts vs What Each Journal Reviews

ScienceDirect is Elsevier’s platform for scholarly literature, and Elsevier describes it as a database of peer-reviewed content. The practical question is narrower: whether the specific article in front of you went through peer review. That is decided by the journal and the article type, not by the platform.

Short answer

Yes for research articles in ScienceDirect journals that run peer review, but not for everything the platform hosts. Elsevier’s product page calls ScienceDirect “the world’s leading database of peer-reviewed, full-text scientific, technical and health literature,” and the same platform also hosts content types such as editorials, news, correspondence and book reviews, whose review status is set by each journal rather than by ScienceDirect.

What Elsevier says ScienceDirect contains

On its ScienceDirect product page (checked 29 October 2026), Elsevier states “more than 3,000 peer-reviewed journals,” 24 million articles and book chapters, 4.2 million validated open access articles, more than 960 open access journals, up to 50,000 books and an additional 180,000 articles from other publishers. These are Elsevier’s own figures as of that date and change over time. The wording matters: the counts describe journals and books, while peer review is a property of how each journal handles each submission.

How Elsevier peer review works

Elsevier’s peer review page (checked 29 October 2026) says the publisher “relies on the peer review process to uphold the quality and validity of individual articles.” It describes these models:

• Single anonymized: the names of the reviewers are hidden from the author. Elsevier presents this as the traditional and most common model. See single-anonymized peer review.
• Double anonymized: both the reviewer and the author are anonymous. See double-anonymized peer review.
• Triple anonymized: a further model on the same Elsevier page; read Elsevier’s page for its exact definition.
• Open: Elsevier gives the most common definition as the reviewer and author being known to each other during the process. See open peer review.

Which model applies is chosen per journal, so two journals on ScienceDirect can differ. A review model tells you how reviewers and authors are shielded from each other; it does not by itself tell you which article types a journal sends out for review.

What is peer reviewed and what is not

ScienceDirect’s help page on article types (checked 29 October 2026) lists 24 types: review articles, research articles, encyclopedia, book chapters, conference abstracts, book reviews, case reports, conference info, correspondence, data articles, discussion, editorials, errata, examinations, mini reviews, news, patent reports, practice guidelines, product reviews, replication studies, short communications, software publications, video articles and other. That page does not state a peer-review rule for each type, and Elsevier’s peer review page does not list excluded types either.

What follows is a practical split. Research articles, review articles and short communications are the types readers usually mean when they ask about peer review, but the journal’s own policy governs. News, editorials, correspondence, errata, book reviews, product reviews and conference info are labels on the platform that should be checked journal by journal before you cite them as peer-reviewed evidence. The label “Other” cannot be assumed either way.

The same applies to open access items. Elsevier’s figure of 4.2 million “validated” open access articles describes content on the platform; whether a given open access article was reviewed is answered by its journal. For how preprints differ, see preprints vs peer-reviewed articles.

How to check a specific ScienceDirect article yourself

1. Open the journal’s homepage on ScienceDirect from the article page (the journal title link) and find its Guide for Authors.
2. Read the sections on peer review and on article types. Journals state which of their article types are reviewed and by whom.
3. Find the article type shown on the article itself and match it to the Guide for Authors.
4. Look for the received, revised and accepted dates on the article. They are consistent with a review process but are not proof of one, so treat them as supporting evidence only.
5. If the item is a book chapter, encyclopedia entry or conference item, check the book or proceedings page for its own editorial process.

A separate question is quality ranking: ScienceDirect hosting a journal says nothing about its impact factor; see whether ScienceDirect has an impact factor. For journals that imitate another title, see hijacked journal. The general definition is under peer review.

Indexing and recognised lists (DOAJ, Scopus, Web of Science, PubMed Central)

Being listed in an index is a separate question from whether a particular article was peer reviewed. Each list publishes its own entry rules, and a journal’s listing tells you only what that list says it checks. The points below were checked on each list’s own site on 29 October 2026.

• DOAJ. DOAJ describes itself as “a unique and extensive index of diverse open access journals from around the world, driven by a growing community.” It covers open access journals only (doaj.org/about).
• Scopus. Elsevier’s Scopus content policy and selection page lists the criteria a title is assessed against. Under journal policy these include a convincing editorial policy and the type of peer review (Scopus content policy and selection).
• Web of Science. Clarivate publishes an “Editorial selection process” page for the Web of Science Core Collection, which says journals are evaluated against 24 quality criteria. Read it directly for the current criteria (Clarivate editorial selection process).
• PubMed Central. Under its scope criteria, PMC states that “the journal must have a clearly stated peer review policy” and must be responsible for the peer review and editorial processes behind its articles (PMC journal guidelines).

To see which lists carry a given journal, search for it on each list’s own site rather than relying on the journal’s own claims.

FAQ

Is everything on ScienceDirect peer reviewed?

No. Elsevier describes the database as peer-reviewed literature, but the platform also lists article types such as editorials, news and correspondence, and each journal decides how those are handled.

Is ScienceDirect a journal or a database?

It is a platform that hosts more than 3,000 journals and books according to Elsevier’s product page. Peer review is performed by each journal’s editors and reviewers.

Are open access articles on ScienceDirect peer reviewed?

Open access describes who can read the article, not whether it was reviewed. Check the journal’s Guide for Authors.

Does the review model matter for credibility?

The model (single, double, triple anonymized or open) describes how reviewers and authors are shielded from or known to each other. It is not a quality grade.
