Availability of submissions
Work submitted to arXiv undergoes a series of quality assurance checks as part of moderation. This helps authors by ensuring their work will be discoverable and archivable and helps readers find relevant research that is in a consistent, readable format.
Quality assurance checks can take between one to four days to resolve, sometimes longer. Authors will be notified by email if any issues are found in the submission. Authors will also receive an email when the submission is posted publicly.
Submissions to arXiv are typically posted publicly Sunday through Thursday, with no announcements Friday or Saturday. You can check the current arXiv time, which also shows the next deadline. Submissions are made public as part of the scheduled announcement process. This includes new submissions as well as replacements, withdrawal notices, cross listings and journal reference.
A note about arXiv-id assignments
The final arXiv identifier is assigned as part of the automated process when the work is announced. It is not possible to generate or to be provided with the arXiv identifier or DOI in advance. Submitting authors will receive an email when the work is announced and it will appear on their account dashboard.
Note: The arXiv identifier cannot be back-dated, so identifiers will be assigned in the month of first announcement. It may be the case that a submission appears in a different identifier month than its original submission date due to various factors.
