Scopus, Web of Science, Google Scholar and PubMed: which database to choose for publication?

Researchers strive to publish their work in reputable journals indexed in prestigious databases such as Scopus, Web of Science, Google Scholar and PubMed. However, choosing a scientometric platform can be quite challenging for both novice and experienced researchers. Which is the best international database to choose for publishing a scientific article? In this review, we will look at the advantages and limitations of each of them to help you make an informed choice.

Scopus

Scopus is one of the largest scientometric databases developed by Elsevier. The platform covers more than 97.3 million scientific publications in natural, technical, medical and social sciences.

Scopus provides researchers with access to reviewed scientific content, indexing only high-quality research that meets rigorous academic standards.

Benefits of Scopus:

• broad coverage of scientific content: Scopus includes more than 28,000 scientific journals across a variety of scientific fields within 330 disciplines
• objective citation metrics: Scopus provides high-quality analytical tools to assess the impact of scientific publications and journals - CiteScore, SJR and SNIP
• international recognition: leading universities, scientific organizations and researchers have access to the database, and publications in Scopus-indexed journals increase the scientific reputation of the author.
• strict quality criteria: each journal is scrutinized monthly to ensure high quality publications.

Disadvantages (limitations of Scopus):

• paid access: without paid subscriptions, limited database functionality is available to users
• limited coverage of national journals: many publications from developing countries are either not indexed or are added with a delay, reducing the visibility of local research
• monthly exclusion of journals that violate database standards: Scopus regularly purges and excludes journals with suspicious publication practices, which can affect the h-index of researchers who have published in such journals. Each month we post an up-to-date list of journals that have been excluded from Scopus. To read the latest update, please go to.

Web of Science

Web of Science (WoS) is a prestigious database that provides a rigorous selection of journals and a high level of peer review. The scientometric platform was developed by Clarivate Analytics. Today, WoS indexes more than 217 million scientific publications in the natural, exact, technical, social and behavioral sciences, as well as the arts.

Advantages of Web of Science:

• high level of quality of indexed publications: all scientific journals indexed in WoS undergo a rigorous peer review process. This ensures that low-quality or predatory journals are not peer-reviewed in the database
• depth of coverage: Web of Science indexes scientific publications dating back to 1864, which allows you to analyze long-term trends in scientific research
• reliable scientometric indicators: Impact Factor (JIF) and Journal Citation Indicator (JCI) are widely recognized metrics in the international scientific community.
• prestige of publication in WoS journals: publication in WoS-indexed publications is often considered more important than in other databases.

Disadvantages (limitations of Web of Science):

• poor coverage of the humanities: despite the existence of a separate index for the humanities and arts, the Arts & Humanities Citation Index, coverage of the humanities is much less than that of the natural and technical disciplines
• slow review process: due to Web of Science's high quality standards, the review process can take 3 to 6 months.
• paid access: full access to WoS is possible only through a paid subscription, which limits its use to independent researchers and small scientific organizations.

Google Scholar

Google Scholar (Google Наука) — is a free scientometric database designed to search for scientific publications, including articles, dissertations, books, preprints, conference proceedings and other scientific content. Unlike Scopus and Web of Science, Google Scholar has no strict selection criteria and automatically indexes a wide range of scholarly literature across all disciplines.

Advantages of Google Scholar:

• free access: unlike the international databases Scopus and Web of Science, Google Scholar is open to all users, making it an affordable tool for researchers worldwide
• wide coverage of sources:  unofficially, Google Scholar covers more scientific content than the authoritative Scopus and WoS platforms. Google Наука indexes not only scholarly articles, but also books, dissertations, technical reports, patents and conference proceedings
• no language restrictions: Google Scholar includes publications in various languages, unlike Scopus and WoS, which are predominantly focused on English-language publications
• simple and user-friendly interface: Google Scholar has a simple and user-friendly interface that allows users to easily find and save publications.

Disadvantages/limitations of Google Scholar:

• lack of rigorous peer review: Google Scholar sometimes includes not only peer-reviewed journals and publications, but also low-quality or predatory journals
• technical problems with citation accuracy: the system may have duplicate entries, incorrect citations, or errors in citation counts. How to fix such flaws, we told you in a previous article — How to add missing citations to Google Scholar?
• lack of scientometric analysis of journals: Google Scholar has no equivalent to Impact Factor or SJR, making it less useful for assessing journal quality.

PubMed

PubMed is the leading medical and life sciences database created and maintained by the U.S. National Library of Medicine (NLM). Today, PubMed covers more than 37 million records from peer-reviewed journals indexed in MEDLINE, as well as other materials such as preprints and books.

Advantages of PubMed:

• free access: PubMed, unlike Scopus and WoS, is available to all users without paid subscriptions
• quality content on medical topics: the database mainly indexes scientific articles from peer-reviewed medical journals, which ensures the reliability of published data
• MEDLINE integration: PubMed facilitates the search of medical content on MEDLINE, where articles are peer-reviewed and indexed using MeSH (Medical Subject Headings).

Limitations (drawbacks) of PubMed:

• focus on medical literature: unlike Scopus and Web of Science, PubMed barely covers the technical, physical and mathematical sciences, social sciences, and humanities
• lack of scientometric indicators: PubMed has no equivalent to Impact Factor, h-index, or SJR, making it less useful for analyzing the impact of journals
• lack of citation information: unlike Scopus and WoS, PubMed does not track how many times an article has been cited by other researchers.

Comparison of databases: Scopus vs PubMed, Web of Science vs Google Scholar

Which is better: Scopus, Web of Science, Google Scholar or PubMed?

The choice between international scientific databases depends on your research goals, available resources and the subject area in which you work. Scopus and Web of Science provide high quality criteria for scientific content and offer advanced analytical tools for evaluating publication activity and citations. In addition, in most countries, publication in Scopus and Web of Science is a prerequisite for obtaining scientific degrees and titles.

At the same time, Google Scholar provides free access to a wide range of scientific materials and is convenient for searching and monitoring citations. PubMed is suitable for those researchers who work in the field of medicine and biological sciences.
