Given the growth of preprint servers and alternative platforms, it is increasingly important to describe their disciplinary scope and compare and contrast policies including governance, licensing, archiving strategies and the nature of any screening checks. These practices are important to both researchers and policymakers.

Here we present searchable information about preprint platforms relevant to life sciences, biomedical, and clinical research.

How to use this directory

Press the “+” icon next to a server’s name to expand the record. Use the search bar to find terms anywhere in the record. Click on the eye icon to select the columns you want to display.

For further details about how the data were gathered, refer to the preprint and source data. Provisional results were presented in January at the #bioPreprints2020 meeting.

Important note: this directory was last updated in January of 2020. We plan to enable periodic updates.
