BioRxiv: Trends and analysis of five years of preprints

Abstract

bioRxiv was founded on the premise that publicly posting preprints would allow authors to receive feedback and submit improved papers to journals. This paper analyses a number of trends against this stated purpose, namely, the timing of preprint postings relative to submission to accepting journals; trends in the rate of unpublished preprints over time; trends in the timing of publication of preprints by accepting journals; and trends in the concentration of published, reviewed preprints by publisher. Findings show that a steady c.30% of preprints remain unpublished and that the majority is posted onto bioRxiv close to or after submission – therefore giving no time for feedback to help improve the articles. Four publishers (Elsevier, Nature, PLOS, and Oxford University Press) account for the publication of 47% of bioRxiv preprints. Taken together, it appears that bioRxiv is not accomplishing its stated goals and that authors may be using the platform more to establish priority, as a marketing enhancement of papers, and as functional Green OA, rather than as a community‐driven source of prepublication review.
