Data Citation Index

Connecting data to the research it informs

Go to product Contact us

The Data Citation Index™ provides a single point of access to quality research data from global repositories across disciplines. Descriptive records are created for data objects and linked to literature articles in the Web of Science.™

As data citation practices increase, the Data Citation Index aims to provide a clearer picture of the full impact of research output, as well as to act as a significant tool for data attribution and discovery.

Data Citation Index: key features

Simple search

Search directly across millions of records from hundreds of evaluated data repositories in the sciences, social sciences, and humanities.

Linked data

Each Data Citation Index record links directly to the repository so that users can quickly access the associated research data.

Tracked and indexed

Citations to data sets and studies are indexed so that you can measure their impact and track their influence.

Recognise and filter

‘Associated Data’ icons in Web of Science Core Collection™ clearly indicate which records have associated data sets attached to them, while an easy to use filter lets you quickly focus a search to discover which records are linked to research data.

Why should data be part of my literature search?

Due in large part to government mandates to make research data freely accessible, there are increasing numbers of data repositories being created worldwide and filled with data by researchers. As part of your literature search, data will provide a more comprehensive picture of the research being undertaken in your topic or field.

By itself, the benefits of data are obvious: data can be used by other researchers with different objectives, results can be reproduced more easily and accurately, researchers receive the credit they’re due, and data producers have a new channel by which to promote their work.

The links between Data Sets and published research in the Web of Science allows researchers to discover relevant research data, while those collecting and depositing data can measure the impact of their work.

Benefits across the research workflow
