What are author identifiers?

Author identifiers, such as ORCIDs, give you a way to reliably and unambiguously connect your names(s) with your work throughout your career, including your papers, data, biographical information, etc. This can be helpful in a number of ways:

• Provides a means to distinguish between you and other authors with identical or similar names.
• Links together all of your works even if you have used different names over the course of your career.
• Makes it easy for others (grant funders, other researchers etc.) to find your research output.
• Ensures that your work is clearly attributed to you.

Research impact is the demonstrable contribution that excellent research makes to academia, society and the economy:

• Academic impact : Contribution to academic advances, across and within disciplines, in understanding, methods, theory and application
• Societal impact: Benefit to individuals, organizations and nations by enhancing quality of life, health and creative output, and increasing the effectiveness of public services and policy
• Economic impact: Attracting investment, wealth creation, enhanced national and global competitiveness

There are several reasons to measure your research impact:

• Application for promotion or tenure
• Quantify return on research investment for grant renewals and progress reports
• Future funding requests
• Identify who is using your work and confirm that it is appropriately credited
• Identify collaborators within or outside of your discipline

Preprint Citation Index

Preprint Citation Index & Support - Web of Science Group

Researchers can now locate and link to preprints alongside other trusted content in the database, to streamline the research process and help make meaningful connections faster.

In academic publishing, a preprint is a version of a research paper or outcome publicly available in online repositories prior to peer review. Access to preprints in the Web of Science makes it quicker and easier for researchers to include them in their existing research workflows. It enables immediate access to up-to-date, aggregated and searchable preprints from selected repositories linked to author profiles.

At launch, the Preprint Citation Index provides nearly two million preprints from the arXiv, bioRxiv, chemRxiv, medRxiv, and Preprints.org 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^™.
