Keep/include the corresponding arXiv information when input the published paper
In some cases when input some paper from journals, I hope that the corresponding arXiv version or link or arXiv number is also automatically found and wrote into the paper info after the input. E.g. arxiv: hep-ph/9404302. This paper is published in Phys.Rev.D. However when I input this article from PRD webpage, the arXiv information for this paper is not found.
This is an old discussion that has not been active in a long time. Before commenting here, you should strongly consider starting a new discussion instead. If you think the content of this discussion is still relevant, you can link to it from your new discussion.
Bibliographically these are discrete publications and are likely to differ in content (and certainly the metadata will differ). I know of several cases of items that have been published in slightly different forms in two --Xiv services and later published as a journal article without mentioning the prepublications.
