Editorial selection process

Web of Science Core Collection

Learn more about selection and criteria

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.

Our collections are dynamic

These dynamic collections undergo continuous curation to remove low-quality journals and ensure that journals are in the most appropriate collection.

Further information can be found in the journal selection process below.

The Web of Science Core Collection selection process

The basic principles of our selection process are objectivity, selectivity and collection dynamics.

We use a single set of 28 criteria to evaluate journals. These are divided into:

24 quality criteria

Designed to select for editorial rigor and best practice at the journal level.

4 impact criteria

Designed to select the most influential journals in their respective fields using citation activity as a primary indicator of impact.

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 on 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’s 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.
