Researchers have launched a database of more than 14,000 studies that have been withdrawn from the preprint server arXiv since its launch in 1991.

As well as shedding light on why those preprints were pulled from arXiv, the data set — called WithdrarXiv — aims to spur the creation of automated tools that flag potential errors to researchers hoping to submit manuscripts, says Delip Rao, a computer scientist at the University of Pennsylvania in Philadelphia, and a co-author of a study describing the tool. Most preprints have not been through formal peer-review or quality-assurance processes.

In the study, itself posted to arXiv on 4 December 20241, Rao and colleagues categorized withdrawn preprints using comments provided by authors about the reasons for removing the study, which ranged from crucial errors to violations of policy. They found that the presence of factual, methodological or other important errors were the most commonly cited reason for withdrawal, with more than 6,000 preprints pulled from the platform because of this. More than 3,100 preprints were withdrawn because they were incomplete or there was more work in the pipeline, and more than 2,800 preprints were pulled because they had been subsumed by another publication (see ‘Withdrawn preprints’).
