Dataset tracking DOIs marked as retracted in Crossref as of April 2023 but no longer marked in Crossref as retracted as of July 2024

This project evaluates the quality of retraction indexing metadata in Crossref. We investigated 208 DOIs that were indexed as retracted in Crossref in our April 2023 union list (Schneider et al., 2023), but were no longer indexed as retracted in the July 2024 union list (Salami et al., 2024), despite still being covered in the Crossref database. Therefore, we manually checked the current retraction status of these 208 DOIs on their publishers’ websites to ascertain their actual status.
