Journal Citation Reports is the only journal report of its kind that is both complete and editorially selective; it contains all the data required to understand the components that index the value and impact of each journal. The structured data are curated by a global team of experts who continuously evaluate and select the collections of journals, books and conference proceedings covered in the Web of Science Core Collection to ensure accuracy in evaluating journal impact.
