Biomedical preprints per month, by source and as a fraction of total literature

Polka, Jessica K.; Penfold, Naomi C.

This is a snapshot of a Google sheet containing counts of biomedical preprints by source and as a fraction of the total biomedical literature through 2020-04.

Note: this does not yet include >6,000 preprints on relevant OSF platforms.

Data sources

arXiv q-bio, PeerJ Preprints, and bioRxiv counts through 2018-12 were sourced from Jordan Anaya's PrePubMed. Following that, arXiv q-bio counts were sourced from arXiv statistics, and PeerJ Preprints and bioRxiv counts were taken from searches of EuropePMC.

All counts from F1000 & Open Research platforms, preprints.org, ChemRxiv, and medRxiv were taken from searches of EuropePMC.

Counts for Research Square are derived from Crossref through 2020-03, thereafter from EuropePMC. Counts for the Lancet and Sneak Peek were taken from web searches.

Total biomedical literature is from PubMed.
