NISO Member News

Additional Specifics

At launch, the Preprint Citation Index provides nearly two million preprints from the arXiv, bioRxiv, chemRxiv, medRxiv, and repositories. Papers from more than a dozen additional repositories will be added throughout 2023. Preprint records are discoverable alongside other scholarly output in the Web of Science and connected to final versions of record, where applicable. They are clearly marked in search results and not included in any citation metrics including Times Cited Counts or the Journal Impact Factor™ (JIF) within the Web of Science Core Collection™ or Journal Citation Reports™.

The Preprint Citation Index enables users to:

  • Locate versions of record (where applicable) for preprints: Find and reference peer-reviewed articles with links from preprints to Web of Science Core Collection
  • Connect preprints to journal articles: Uncover connections between cutting-edge preprints indexed in the Preprint Citation Index and journal articles indexed in the Web of Science Core Collection via citation linking.
  • Expand the view of a researcher’s expertise: Place preprints in the context of a researcher’s career with preprints displayed on an author’s Web of Science Researcher Profile.
  • Monitor new research across several repositories: An author can set an alert for keywords or a named researcher of interest to be notified when relevant preprints become available.
