Estimating the growth of preprint review over time.

Preprints evaluated per month on Sciety, excluding reviews conducted by automated tools (ScreenIT) and reviews by journals posted after publication of the journal version (source data available [20]). This chart includes data from the following services, regardless of which server the preprints they evaluate have been posted to: eLife, Review Commons, Arcadia Science, preLights, Rapid Reviews, PREreview, NCRC, Peer Community In (Evolutionary Biology, Ecology, Zoology, Animal Science, Neuroscience, Paleontology, Archaeology), PeerRef, Biophysics Colab, ASAPbio (and ASAPbio-SciELO) crowd review, Life Science Editors (including Foundation), and The Unjournal. Data have been collected and provided by Sciety. Reviews posted to comment sections of preprint servers are not included, and depending on the policies of individual services, some of the evaluations included in this chart may not meet our definition of preprint review.</p
