Summary files (in XML format) listing URIs referenced in papers from arXiv, Elsevier, and PMC respectively (approximately 1 million URIs from 3 million papers in total). The focus of the Hiberlink project was to assess the extent of so-called ‘reference rot’, investigating how web links in online scientific and other academic articles fail to lead to the resources that were originally referenced.
