Data for Appendix 10 PMID Duplication in the Union List of "Analyzing the consistency of retraction indexing"

CORRECTED 2026-07-14: Our CSV file removed two rows (DOI 10.4103/0970-0218.44520 and DOI 10.4103/0970-0218.51231 previously both associated with PMID 19876456) that were in V1: After we removed items from Retraction Watch that are not in their "Retraction" category, the PMID was no longer duplicated in our dataset.

This project investigates retraction indexing agreement among data sources: BCI, BIOABS, CCC, Compendex, Crossref, GEOBASE, MEDLINE, PubMed, Retraction Watch, Scopus, and Web of Science Core. Post-retraction citation may be partly due to authors’ and publishers' challenges in systematically identifying retracted publications. To investigate retraction indexing quality, we investigate the agreement in indexing retracted publications between 11 database sources, restricting to their coverage, resulting in a union list of 83,317 unique items. This dataset highlights items that went through a DOI augmentation process to have PubMed added as a source and that have duplicated PMIDs, indicating data quality issues.
