The Nature Index is a database of author affiliation information collated from research articles published in an independently selected group of 68 high-quality science journals. The 68 journals of the Nature Index represent less than 1% of the journals covering natural sciences in the Web of Science (Thomson Reuters) but account for close to 30% of total citations to natural science journals.
