To close this gap, we release Wikipedia doi.org/10.1162/qss_a_00105 Citations, a comprehensive data set of citations extracted from Wikipedia.

We were thus able to extract Received: 14 July 2020 4.0 million citations to scholarly publications with known identifiers—including DOI, PMC, Accepted: 23 November 2020 PMID, and ISBN—and further equip an extra 261 thousand citations with DOIs from Crossref.
