The Nature Index is a database of author affiliation information collated from research articles published in an independently selected group of 82 high-quality science journals. The database is compiled by Nature Research. The Nature Index provides a close to real-time proxy of high-quality research output and collaboration at the institutional, national and regional level.
The Nature Index is updated monthly, and a 12-month rolling window of data is openly available at www.natureindex.com under a Creative Commons non-commercial license. The Nature Index also releases annual tables of country- and institution-level calendar-year output back to 2015, as well as an archive of the annual tables released in previous years.
