Data Citation IndexSM on the Web of Knowledge platform provides a single point of access to quality research data from repositories across disciplines and around the world.

Through linked content and summary information, this data is displayed within the broader context of the scholarly research, enabling users to gain perspective that is lost when data sets or repositories are viewed in isolation. These connections allow researchers to efficiently access to an array of data across subjects and regions, providing a comprehensive picture of research output, to maximize research efforts and accurately assess importance.

Repository identification and selection are continuous and ongoing at Thomson Reuters, with repositories added as frequently as weekly. Moreover, existing coverage is constantly under review. Repositories now covered are monitored to ensure that they remain available and are maintaining high standards and a clear relevance to the Data Citation Index product. Research data considered for inclusion include data studies and data sets deposited in a recognized repository.



Before submitting your repository for evaluation, please read the Repository Selection Essay to ensure your repository qualifies. Thomson Reuters requires certain information about a repository in order to perform an evaluation.
