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.
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.
Each editor is focused on specific subject categories, enabling them to gain a deep, nuanced knowledge of journals in that field.
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 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.
We use a single set of 26 quality criteria designed to select for editorial rigor and best practice.

As an independent organization, Clarivate does not become involved in and is not responsible for the editorial management of any journal or the business practices of any publisher. Publishers are accountable for their journal performance and compliance with ethical publishing standards. The views and opinions expressed in any journal are those of the author(s) and do not necessarily reflect the views or opinions of Clarivate. Clarivate remains neutral in relation to territorial disputes, and allows journals, publishers, institutes and authors to specify their address and affiliation details including territory.
Criteria for selection of newly submitted titles and re-evaluation of existing titles in the Web of Science are determined by the Web of Science Editors in their sole discretion. If a publisher’s editorial policy or business practices negatively impact the quality of a journal, or its role in the surrounding literature of the subject, the Web of Science Editors may decline to include the journal in any Clarivate product or service. The Web of Science Editors, in their sole discretion, may remove titles from coverage at any point if the titles fail to maintain our standard of quality, do not comply with ethical standards, or otherwise do not meet the criteria determined by the Web of Science Editors. If a journal is deselected or removed from coverage, the journal will cease to be indexed in the Web of Science from a date determined by the Web of Science Editors in their sole discretion – articles published after that date will not be indexed. The Web of Science Editors’ decision on all matters relating to journal coverage will be final.
