This report projects the number of COVID-19 preprints expected to be published on a weekly basis.
The first tab shows the numbers of COVID-19 preprints indexed in Europe PMC for each repository on a weekly basis. The data are based on a query for “COVID-19” or “SARS-CoV-2” appearing in the title or abstract. The second tab shows the repositories currently included in the COVID-19 full-text project. The final tab compares preprints and journal publications.
The repositories in the full-text COVID-19 preprint project are: bioRxiv, medRxiv, ChemRxiv, Research Square, SSRN, arXiv
Based on the currently weekly rate of preprint publication (version 1 only), the weekly publication count is projected three months into the future for the various repositories. A projection for journal articles is also included.
