Editorial selection process

The robust evaluation and curation of our data make the Web of Science Core Collection™ the world’s most trusted publisher-independent global citation database.

Curated by an expert team of in-house editors, the Web of Science Core Collection is a trusted, high-quality, definitive database for journals, books, and conference proceedings. We are guided by the legacy of Dr Eugene Garfield, inventor of the world’s first citation index: we remain true to his principles of objectivity, selectivity and collection dynamics, but also adapt and respond to technological advances and changes in the publishing landscape.

A unique curation process

  • Publisher neutral
    Our editorial decisions are conducted by our expert in-house editors who have no affiliations to publishers or research institutes – removing any potential bias or conflict of interest.
  • Category knowledge
    Each editor is focused on specific subject categories, enabling them to gain a deep, nuanced knowledge of journals in that field.
  • In-house curation
    Our rigorous process for the Web of Science Core Collection contrasts with that for other databases that rely on algorithmic approaches and/or delegating aspects of editorial decision-making to the research community.

The Web of Science Core Collection selection process

The basic principles of our selection process are objectivity, selectivity and collection dynamics. Our selection processes are designed to ensure that only trustworthy publications and reliable content are covered in our indexes.


We use a single set of 28 criteria to evaluate journals: 24 quality criteria designed to select for editorial rigor and best practice, and four impact criteria designed to select the most influential journals in their respective fields.


We use a single set of 18 quality criteria designed to select for editorial rigor and best practice.

Conference Proceedings

We use a single set of 26 quality criteria designed to select for editorial rigor and best practice.

Editorial Disclaimer

As an independent organization, Clarivate does not become involved in and is not responsible for the editorial management of any publication or the business practices of any publisher. Publishers are accountable for their publications’ performance and compliance with ethical publishing standards. The views and opinions expressed in any publication are those of the author(s) and do not necessarily reflect the views or opinions of Clarivate. Clarivate allows journals, books, proceedings volumes, publishers, institutes, and authors to specify their address and affiliation details including territory.

Criteria for selection of any submitted titles and re-evaluation of existing titles in the Web of Science are determined at the sole discretion of Clarivate. If a publisher’s editorial policy or business practices negatively impact the quality of a publication or its role in the surrounding literature of the subject, Clarivate may decline to include the publication in any Clarivate product or service. Clarivate, in its sole discretion, may remove or deselect a publication or journal from coverage (including a content already indexed in the Web of Science) at any point if the publication or journal fails to maintain our standard of quality, does not comply with ethical standards, or otherwise does not meet the criteria determined by Clarivate. The publication will have no further content indexed from a date determined by Clarivate in its sole discretion.

Books or proceedings volumes may be removed from Web of Science indexing if the content is later found to have major flaws that affect the quality of the Web of Science database.

Clarivate’s decision on all matters relating to content maintained in the Web of Science collections will be final.
