    <subfield code="a">&lt;p&gt;This is a snapshot of a &lt;a href="https://docs.google.com/spreadsheets/d/1c1WzYIoLhzY09AkwyhSVDtan3oYV8qrHa3WgPHAeVVM/edit?usp=sharing"&gt;Google sheet&lt;/a&gt;&amp;nbsp;containing counts of biomedical preprints by source and as a fraction of the total biomedical literature &lt;strong&gt;through 2020-06.&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;Note: this does not yet include &amp;gt;6,000 preprints on relevant OSF platforms.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Data sources&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;arXiv q-bio, PeerJ Preprints, and bioRxiv counts through&amp;nbsp;2018-12 were sourced from Jordan Anaya&amp;#39;s &lt;a href="https://github.com/OmnesRes/prepub/tree/master/analyses"&gt;PrePubMed&lt;/a&gt;. Following that, arXiv q-bio counts were sourced from &lt;a href="https://arxiv.org/year/q-bio/19"&gt;arXiv statistics&lt;/a&gt;, and PeerJ Preprints and bioRxiv counts were taken from searches of &lt;a href="https://europepmc.org/"&gt;EuropePMC&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;All counts from F1000 &amp;amp; Open Research platforms, preprints.org, ChemRxiv, and medRxiv were taken from searches of &lt;a href="https://europepmc.org/"&gt;EuropePMC&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Counts for Research Square are derived from Crossref through 2020-03, thereafter from EuropePMC.&amp;nbsp;Counts for the Lancet and Sneak Peek were taken from web searches.&lt;/p&gt;

&lt;p&gt;Total biomedical literature is from PubMed.&lt;/p&gt;</subfield>
