To update or revise content already posted on ESS Open Archive, click your name in the upper-right and choose My Documents. Select the preprint or presentation to be modified. Make a change to the document, and then choose Publish. Publishing a revision will create a new DOI but will retain the earlier version of the document. Revisions undergo the same screening process as new submissions. All prior versions remain posted on ESS Open Archive with appropriate date and time stamps as they are part of the citable scientific record. Previous versions remain accessible via the submission timeline on the publication page. You may make changes to Supplemental Files with a new version, or keep them the same. Edits to Supplemental Files require a new version, even if no changes have been made to the main preprint/poster.
