The Nature Index is a database of author affiliation information collated from research articles published in an independently selected group of high-quality science journals.
The Nature Index annual tables show calendar year performance and ranking positions for the world’s leading research institutions, plus data from previous calendar years to support analysis of trends over time. The data behind the annual tables is freely accessible, enabling users to examine patterns of publication and collaboration down to the article level where media impact is measured using Altmetric.
