Why choose the Web of Science Core Collection?

Our process of curation is unique

Editorial decisions are conducted by our expert in-house editors, who have no affiliations to publishing houses or research institutes. Using objectivity, selectivity, and collection dynamics as the basic principles of our selection process, we use a single set of 28 criteria to evaluate a journal’s quality (24 quality criteria) and influence (4 impact criteria). These are dynamic collections, subject to continuous curation, to ensure journals continue to meet our editorial standards and are in the appropriate collection.
