The Nature Index covers all institutions that have been listed in the affiliations of articles included in the index. The Nature Index search function enables you to find the results for a specific institution among the 10,000+ parent institutions tracked by the Nature Index. Great care has been taken to disambiguate institutional names and to aggregate the multiple versions of names for the same institution that can occur. Furthermore, every effort has been made to include all affiliated institutions within larger institutional organizations and, where possible, a breakdown of those component institutions is also given. We are always open to suggestions of ways to improve presentation of complex institutions and their affiliations.
