+100 on this. It would be great though to simply have a field arxivid (that could be potentially activated on request). This would catch the case that the same article is on multiple preprint servers (which could happen I guess).
How has this end up?Today I used Chrome connector to add a preprint and on the Zotero library it appeared as Item Type: Report, Insitution: bioRxiv and on Extra it had the DOI
Still applies
