Preprint servers facilitate rapid dissemination of research and allow researchers to share preliminary results and receive peer feedback ahead of formal publication to improve their work and establish priority. All content posted on ESS Open Archive receives a DOI and is citable and freely accessible. Preprints will, where possible, link and resolve to the official published version of record, once available. 
ESS Open Archive also allows researchers to preserve their posters or slide presentations from recognized scientific conferences. We allow, and encourages, linking to data sets in leading repositories or other online resources such as iposters and videos .  Jupyter notebooks can also be included as supplements. ESS Open Archive also provides an archive for official materials of scholarly societies.
