How to add DOI to the published version of an article in arXiv? I uploaded an article to arXiv which has been published in The Astrophysical Journal after referee suggested edits and final proof. How do I cross ref the arXiv version with the DOI of the published version? Do I just cross-ref the DOI of published version with the older version in arXiv or do I download the published pdf and upload it with DOI as a new version in arXiv? (I think the latter is not allowed as when I uploaded the published version of another paper as full-text on researchgate, I was told to remove it).
The arxiv has a dedicated field where you can add the DOI.  (Note that this will not create a new version.)
In addition, most journals will allow you to upload the final accepted version (that is, the version with the corrections you did following the referee comments, but without any copyediting done by the journal), so you can additionally upload that version when you add the DOI (and potentially clarify in the &quot;comments&quot; field that this is the accepted version).
